Transcripts

00:00

how dangerous do you think is a really

00:02

powerful

00:03

slingshot you'd be

00:08

surprised I definitely was I'm talking

00:11

about slingshots that generate more

00:13

momentum than a 45 caliber firearm and

00:16

I'm not even saying that to be over

00:17

dramatic they actually tested it and

00:20

finding that out made me pretty upset

00:23

because a few weeks ago I made a video

00:24

testing a bunch of slingshots trying to

00:26

find out how dangerous they are and

00:29

while I used to love that video and now

00:31

I don't because it's completely

00:32

inaccurate all the sling shots I tested

00:35

in that video are simply toys compared

00:38

to the really powerful ones and so to

00:41

redeem myself and actually answer the

00:43

question well I'm going to try to build

00:45

one of the most powerful slingshots on

00:47

the planet a slingshot capable of ending

00:49

anything in front of it and behind of it

00:52

compare it to the best slingshot of the

00:54

previous video and then see what happens

00:56

when I test it against a ballistic dummy

00:57

this is the Prototype I made for my

00:59

custom slingshot and I'm going to

01:01

explain the features of each component

01:02

as I build them starting from the fork

01:05

this is where I'm going to attach

01:06

multiple elastic bands and throw massive

01:08

steel boss with them and so it needs to

01:10

be really tough if while pulling the

01:12

bands one of these two pieces broke it

01:14

will fly towards me like a bullet and

01:17

that my friend might be the end of the

01:19

video and the channel sorry Mom well to

01:23

avoid that I made a sandwich of

01:25

materials that I'm going to glue

01:26

together to create the elements of the

01:27

slingshot the sandwich has a strong core

01:30

to make it tough and for that I could

01:32

have used aluminum hardwood or even

01:34

steel but I got a lot of polycarbonate

01:36

laying around from a previous video and

01:38

since it's an incredibly tough material

01:40

I decided to go with this

01:43

one then I prepared a few thin sheets of

01:46

wood and also red acrylic to place on

01:48

top of the polycarbonate these are

01:50

mainly there for aesthetic reasons and

01:52

the effect I would like to obtain is

01:54

something like this aim for the Stars

01:56

they said anyways to glue the layers

01:58

together I'm going to use epoxy

02:00

which should work with all the layers of

02:02

the sandwich but just to be extra safe

02:04

I'm also sending the surfaces of

02:06

polycarbonate and acrylic so that the

02:08

glue can form a stronger bond with them

02:10

so I'm pouring the two components of the

02:12

glue into a cup I mix them together for

02:14

a while looks like I'm cooking or

02:16

something and then I'm spreading it

02:18

evenly on each surface of the layers the

02:20

problem is that I used way too much

02:22

epoxy and now the layers keep sliding on

02:24

each others so now I'm panickin while

02:26

trying to clamp everything down woring

02:28

the layers are going to get stuck in the

02:30

wrong position I have to throw

02:31

everything away and L another day

02:33

starting from scratch but it ended up

02:35

working now I got to wait 3 days it's

02:37

been 3 days I'm going to remove the

02:39

clamps and see if it actually worked had

02:41

a few doubts about this one are the

02:43

clamps even going to come out and yes

02:47

they do kind of two did the epoxy dry

02:51

and are the layers fixed in place also

02:54

yes it feels pretty solid and three how

02:57

strong is the connection between the

02:58

layers well either the rising is really

03:01

strong or I am really weak but the

03:03

reality is that there is not an answer

03:04

for this one right now I just got to

03:06

hope for the best and see what happens

03:08

when I test it the next step is croping

03:10

the shape of fork handle and arm brace

03:13

out of the sandwich block to do that I'm

03:15

using a band saw and after the first cut

03:18

I'm happy to see that there is no gap

03:20

between the layers which is definitely a

03:22

good sign and so I'm training to cut all

03:24

the elements following their shapes as

03:26

fast as I

03:27

can and it took me about 4 minutes but

03:30

here they are Fork handle and arm brace

03:34

or at least the rough shape of them now

03:36

I'm going to use the belt grinder to

03:38

smooth out the edges and the surfaces

03:40

starting with the fork right now it's

03:42

definitely thick but the idea is to

03:44

grind it in a way that it's going to

03:46

make the pattern come out the problem is

03:48

that I massively underestimated this

03:50

step and massively overestimated my

03:52

skills and after 30 minutes of absolute

03:55

random grinding all right I completely

03:58

messed up

04:03

like no it doesn't look bad it's just

04:07

Modern Art and you don't understand it

04:09

I'm joking so I'm going to make a

04:10

simpler and better one the good news is

04:13

that with a spare Fork I can test how

04:15

tough it is

04:19

yep it's perfect so I prepared new

04:22

layers glued them with epoxy waited

04:25

cropped smoo in the edges grinded being

04:28

extra careful do not mess it up again

04:31

and now I'm back to where it stopped

04:33

next I'm using this fascinating machine

04:34

to smooth the edges and honestly I

04:37

started to get pretty excited and this

04:39

is how the fork looks now I swear I'm so

04:43

proud now I need to send it then polish

04:45

it to make the wood shiny and the

04:47

polycarbonate transparent and then I'm

04:49

going to do the handle and the arm brace

04:51

the same basically the same way I didn't

04:53

even finish the fork and I'm already

04:54

thinking about when this thing is going

04:56

to be done and when I'm going to be able

04:58

to test it before that though I need to

05:01

send it and I already know sending is

05:02

going to take a while I need to go from

05:04

a 2200 GD sandpaper to a th000 grit and

05:08

paper so I'm going to just skip this

05:10

process but while my slightly younger

05:12

self suffers for the next 5 hours I want

05:15

to thank this plate for supporting this

05:17

project and yes that thing moves I just

05:19

finished the workshop and I wanted to

05:21

personalize it a little bit so I picked

05:23

a few posters and they just arrived and

05:25

they looked good from their website but

05:27

seeing them in person it actually got me

05:29

excited this is

05:31

insane it's so cool Spyro I used to play

05:35

this with my sister on our PS1 when we

05:37

were kids she's about to have a baby

05:40

now I love it the posters feel high

05:43

quality and sturdy let me try to zoom in

05:46

and the clarity on the images is really

05:48

good this plate also just launched a new

05:50

product called displate Textra which

05:52

basically gives extra Clarity to the

05:54

images by having a 3D texture on the

05:57

posters hanging the posters is also

05:59

intuitive and fast and this plate gives

06:01

you all the tools you need wipe the wall

06:03

stick the protective Leaf stick the

06:05

magnet to the leaf I'm using a 3D one

06:07

but they also have it

06:08

flat and that's it basically took me

06:11

like 4 minutes to set up three posters

06:13

there are over 2 million artworks

06:15

available in the displayed catalog and

06:17

you can pick from original art or

06:19

license design like Star Wars Marvel

06:21

Elden ring or Dune I wish I got that one

06:24

actually you can also get them right now

06:26

by going to display.com shake or use my

06:29

prom code M shake and you get a really

06:31

nice discount I'm also leaving a link in

06:33

description if you want to check them

06:34

out at the end of the video anyways 5

06:36

hours later the sending was completed

06:38

then I used an improvised buffing

06:40

machine to polish the polycarbonate and

06:42

after grinding a little slot where I'm

06:43

going to attach the elastic bands I

06:45

finish the fork using Lin seed oil and

06:48

wax and here it is I really like how it

06:51

turned out but maybe it's just because I

06:53

made it kind of like my mom that likes

06:54

me regardless well for sure it's better

06:57

than the last one it's a so pretty big

07:00

this is how it looks compared to a

07:01

normal slingshot but it should fit well

07:04

the kind of power I'm going for all

07:05

right I'm going to make the handle and

07:07

the arm brace and so I did it all over

07:09

again for the arm brace which luckily

07:11

took much less compared to the fork

07:13

thanks to the simpler shape and after

07:15

sending it this is how it looks now the

07:18

last element I need to make is the

07:20

handle aside from smooting out the edges

07:22

I'm trying to grind the handle to make

07:24

it fit perfectly with my hand so I keep

07:27

grinding and testing it then I just

07:29

adjusting it based on how it feels and

07:31

after completing the rough shape I spent

07:33

a few hours sending it by hand to smooth

07:35

out the curves as much as possible and

07:37

as the last step I'm applying the oil as

07:39

I did with the previous elements this is

07:41

how the final handle looks and I like it

07:44

but most importantly it feels very

07:45

comfortable and I can't wait to test

07:48

this thing like that all the elements

07:50

are done now I can put them together

07:52

with the main frame and then I'm going

07:54

to test it against the targets my custom

07:56

slingshot increases the draw length

07:58

compared to a normal one basically how

08:00

far I can stretch the bands before

08:02

releasing them and with more elastic

08:04

mass the power increases exponentially

08:06

so to connect all the elements together

08:08

I'm going to use this steel profile I

08:10

need to cut it a little bit first I'm

08:12

not exactly sure how long should I make

08:14

this Frame though the longer the better

08:17

but I need to be able to use it so I'm

08:19

just measuring the distance between arm

08:20

brace and handle and based on that I

08:23

ended up using another profile I had in

08:25

the shop this one is exactly 1 M and if

08:29

this version ends up being too weak I'm

08:32

going to use the longer stick to make an

08:34

even more extreme version for that

08:36

reason I also want all the elements to

08:38

be removable from the main frame and so

08:40

to connect them to the frame I thought

08:41

about using steel brackets I'm not sure

08:44

if this is the best way to do it though

08:46

if I making a mistake let me know right

08:48

now so that I can stop before this thing

08:50

flies towards me when I test

08:53

it all right if I die it's your fault so

08:56

I cleaned up the profile using the Bel

08:58

grinder and then I I send it by hand

09:00

fixing the mistakes I made on the B

09:02

grinder one day I'm going to learn how

09:05

to use this thing but today is not that

09:07

day anyways this is how the steel

09:09

profile ended up looking now to connect

09:12

the brackets to the frame I'm drilling

09:13

three holes of 5 mm into the steel

09:16

profile basically like this after that I

09:19

can install the brackets in which I'm

09:20

going to place the fork I actually also

09:22

mounted two brackets at the end of the

09:24

seel bar so that this way I can connect

09:26

the arm brace to one end of the profile

09:28

and the fork to the other through that

09:30

though I also need to drill a few holes

09:32

into the elements and this step is kind

09:34

of scary because the acrylic could

09:37

shatter in the process and that would

09:38

mean starting from scratch So to avoid

09:41

that I'm using a special

09:44

bit that should work both with plastic

09:47

and wood then I started drilling three

09:49

holes into the fork this process took me

09:52

like 30 minutes I went very very slow to

09:56

avoid damaging the layers and I think it

09:58

kind of worked at this point I can

10:00

insert the balls that I actually grinded

10:03

to make them look nicer and I also added

10:05

three rubber spacers since the back of

10:07

the wood is not perfectly flat and I

10:09

hope this will help distribute the

10:11

pressure I think it works yes I believe

10:15

it looks pretty good but the best part

10:18

is not even the look what surprised me

10:20

the most is how premium it feels even

10:23

who built it it doesn't wobble at all it

10:25

doesn't make noises and it feels very

10:28

sturdy now I'm repeating the process to

10:30

install the arm brace and this is how it

10:32

looks on the profile and seeing it like

10:34

that makes me pretty confident this

10:36

thing is going to crush

10:38

bones hopefully not mine anyways only

10:41

the handle is missing at this point and

10:43

I'm not exactly sure what's the best way

10:45

to connect this one and so I'm doing the

10:48

first thing I thought about I'm drilling

10:49

a big hole into the handle and my plan

10:52

is to glue a steel rod into it so that

10:54

then I can easily mount it to the frame

10:56

to glue the rod I'm using a fast drying

10:58

glue that should work well with

11:01

polycarb that wasn't a crack it was air

11:04

coming out of the handle now there is

11:06

one Last Detail I need to add to the

11:07

handle the bols on the fork and the arm

11:09

brace basically act as spins providing

11:12

extra strength to keep the layers

11:14

together and since the handle doesn't

11:15

have those I decided to add four small

11:18

bols to it they don't compromise the

11:20

comfort and this way I'm sure the layers

11:22

are going to stay together even if I

11:23

drop it and to mention the words of a

11:25

wise German man I'm going to introduce

11:27

in a bit it's not ugly

11:29

it's effective now I'm mounting the

11:31

handle using a piece of ladder to

11:33

distribute the stress between the handle

11:35

and the frame and like that the custom

11:38

slingshot is ready I really believe this

11:40

could be up there with the most powerful

11:42

slingshots in the world but I guess I'm

11:44

going to find out soon when I test it I

11:46

don't know if I should be excited or

11:50

scared I'm excited though but the reason

11:53

why I picked this design over some

11:55

crazier ones ahead is pretty fascinating

11:58

it looks fairly simple but this design

12:00

should be the most powerful one you can

12:02

make for a handeld slingshot and the

12:04

reason why I know that is this man hello

12:06

and welcome to the slingshot Channel

12:08

while checking the comments in my

12:09

previous slingshot video I saw this one

12:12

that threw me right into the rabbit hole

12:14

that actually made me start this project

12:16

yorg is a German God right on top of the

12:19

slingshot foot chain and he set a world

12:22

record of 135 ju with a 25 mm steel ball

12:26

and just to clarify 135 ju is closer to

12:29

a small firearm in terms of power than

12:32

it is to a normal slingshot and since I

12:34

don't have much experience with

12:35

slingshots and most importantly I'm not

12:38

German I reached out to him and he

12:41

actually replied yor gave me a lot of

12:44

valuable information that allowed me to

12:46

get to this point and most importantly

12:48

he made me realize that there is a

12:50

serious risk involved in what I'm about

12:52

to do and he also suggested me to scrap

12:54

all my other designs besides this one I

12:56

build and it's basically a new version

12:58

of the Starship which is the slingshot

13:00

he used to set the word record and so

13:03

now I can install the bands and then I'm

13:05

going to test it the size and the number

13:07

of layers you need depends on the weight

13:09

of the ammo you're using heavier ammo

13:11

require more bands which are much harder

13:14

to pull but they also generate more

13:16

power so to find out the dimensions of

13:18

the Bands they need for all the bosss

13:20

I'm going to test I'm using an equation

13:21

that York created basically based on the

13:24

weight of the ammo you use and the draw

13:26

length it TS you the dimension and the

13:28

number of bands you need and to find my

13:30

draw length I measured my draw length

13:32

with a normal slingshot have no idea if

13:34

this is the right way to do it and I

13:36

added the extra length of the frame with

13:38

that I got a total of 198 CM which is a

13:42

lot but I'm using a smaller one to be

13:44

conservative for maximum performance

13:46

bands also need to be tapered basically

13:48

they need to be larger towards the fork

13:50

and smaller towards the pouch this

13:52

allows the ammo to accelerate faster and

13:54

therefore increase the speed and the

13:56

power after that I can attach the bands

13:58

to the pouch and the process is pretty

14:01

straightforward little bit spit for the

14:02

most part of it Al the friction causes

14:05

not to get all messed up and you can

14:06

actually just break the and here is how

14:09

they look at this point I can attach the

14:11

bands to the slingshot and like that the

14:13

build is finally

14:15

completed it's ready and so now there is

14:18

only the fun and potentially little step

14:21

left all right then let's test it now

14:23

before risking my life with a massive

14:25

balls I want to find out if my custom

14:27

slingshot well if you works and also if

14:30

it's actually more powerful than the

14:32

ones I tested in my old video and so I'm

14:34

going to gradually increase the

14:35

dimension of the ammo and the number of

14:37

bands and I'm going to measure energy

14:39

penetration and damage for each one of

14:44

them I feel like a

14:46

juggernaut I know you're probably

14:48

thinking it's maybe too much for this

14:50

small ammo I'm actually worried it's not

14:52

going to be

14:53

enough but I guess there is only one way

14:56

to find out

15:00

and well it turns out that this thing

15:02

works pretty well 125 yeah it's fast out

15:07

of five shots the best one I got is 130

15:09

m a second or 426 ft per second and if

15:13

you consider that a 9 mm bullet travels

15:16

at around 1200 ft per second that's a

15:20

lot so with the 8 mm seal bar the custom

15:23

slingshot generates 1.6 times more

15:26

energy than my best sold one this is the

15:28

weakest set up I'm going to test and it

15:30

already broke the catch boox behind the

15:32

wooden panel I also tested a different

15:35

brand of rubber but I got very similar

15:37

results so now it's time for the second

15:39

test with the 8 mm

15:41

ball penetration and at my first shot

15:44

the ball went on the side of the gelatin

15:46

block and I actually thought it was a

15:48

fluke no cuz it went way too deep oh no

15:51

way jeez but then when he tried

15:55

again the second shot was perfectly in

15:57

the middle and he went deeper than the

16:00

first if we compare the penetration of

16:01

my old slingshots compared to this one

16:05

this is insane the old slingshots are

16:07

also not lethal with an 8 mm Ball but

16:10

given this

16:13

penetration do you think it's going to

16:14

be lethal 8 mm ball test number three

16:18

damage and so I stretched the bands as

16:20

much as I could and I

16:23

shot no way at first I thought the ball

16:26

actually cracked the skull but then then

16:29

I saw it it stopped the ball went into

16:31

the gelatin but it stopped on the

16:33

skull let's keep it there also what's

16:36

wrong with your nose man J I didn't

16:38

notice that anyways this slingshot is

16:41

already more impressive than the ones I

16:43

tested in my old video and this is

16:44

literally the weakest possible setup I

16:46

have for this one so I'm very curious to

16:49

see what's going to happen with the big

16:50

balls but in the meantime these are all

16:52

the result I got with the smallest one

16:54

next I'm shooting 10 mm steel balls and

16:57

to shoot them I'm going to use a double

16:59

layer setup basically two bands per side

17:02

and I was expecting the 10 mm BS to be

17:05

significantly slower compared to the

17:07

previous ones but the

17:09

speed actually didn't drop very much 11

17:13

19.1 that's a lot out of five shots the

17:16

best one I got was

17:27

124.401 in bigger boss to have less

17:30

penetration

17:32

power

17:33

but it almost went through with a 10 mm

17:37

steel ball I got a penetration of 13.9

17:40

CM before trying the ballistic dummy I

17:43

also want to shoot a few different

17:44

targets this is not part of the official

17:46

test and I could totally avoid it but I

17:50

won so I shot a

17:52

watermelon then a coconut which is

17:55

pretty hard but it still went straight

17:57

through and then a sakan

18:01

and at this point I'm kind of thinking

18:03

this might be lethal already all

18:07

right nope wait what is

18:12

that that was

18:19

anticlimactic I'm not exactly sure if he

18:22

bounced on the bone or he just went

18:24

straight there either way I'm going to

18:26

try again aiming at the forehead

18:33

oh no way went once again perfectly

18:36

inside the eye in the other

18:40

one come on I'm going to try to hit it

18:45

again but once again it didn't crack so

18:48

I think the bosss were just bouncing off

18:50

the bones anyways these are all the

18:52

results I got for the 10 mm steel

18:56

balls and now it gets scary 20 mm lead

18:59

bosss like these are the bands I just

19:02

used and these are the bands I'm going

19:04

to use now three huge flat bands per

19:06

side and for this one I also had to

19:08

build a bigger pouch I'm scared for the

19:11

first time since I started testing this

19:14

thing now I'm actually scared as a

19:17

disclaimer I don't think this is wise I

19:19

don't think this is safe and I don't

19:21

think it's going to be enjoyable to use

19:22

a monster like that but I just want to

19:25

go for it this is how it looks with the

19:27

flat bands connected to it and with that

19:29

I'm ready to try it kind of and well as

19:32

expected these bands are way harder to

19:34

pull compared to the previous ones but

19:36

even though this setup highlights my for

19:38

technique and the lead ball actively

19:41

tried to kill me it was actually working

19:44

pretty well how much was

19:47

that 57.9 and that means 79.3 Jew of

19:52

energy which is a lot still I wanted to

19:54

keep trying for two reasons first

19:57

because I know I can top my previous

19:59

speed I just need to develop a slightly

20:01

decent technique and build up confidence

20:03

and second because I'm kind of loving

20:05

the distraction this thing is able to

20:07

generate and I can't wait to test it

20:09

against the targets but then I made a

20:12

mistake somebody said that if you run

20:14

when you can't

20:15

walk you'll probably fall and that was

20:19

the sound of the steel ball here in the

20:22

fork I broke

20:25

it

20:27

yeah [ __ ] it

20:30

I broke the fork that's a bad one this

20:33

has been a very unfortunate turn of

20:36

events I got an allergy reaction it's

20:38

pouring and it wasn't even supposed to

20:41

rain my slingshot

20:44

broke on the other side though I'm still

20:47

alive and most importantly though the

20:49

polycarbonate is very tough indeed it

20:51

doesn't even have a scratch on it and so

20:53

I found a temporary fix so that I can

20:55

keep using it you know it is what it is

20:57

it just lived long enough to become the

20:59

villain so I'm going to just wait for

21:01

the Sun and then I'm going to finish the

21:03

test how's it going guys today's

21:05

tomorrow and sunshines now you know why

21:07

that happened by watching the slow

21:09

motion of the incident I realized that I

21:11

pushed down my hand right before

21:13

releasing the pouch and well I just got

21:16

to try avoid doing that again I also

21:18

just built a much deeper armrest since

21:20

the helmet sticking out made it kind of

21:22

hard to stretch the BS comfortably all

21:25

right then let's see what happens I'm

21:28

going to just try to stretch this as

21:30

much as I can so if you hear weird

21:32

noises that's why and so I wanted to

21:35

measure the energy once again and after

21:37

shooting at the Target a few times I

21:40

actually topped the previous result 59.6

21:43

59.6 yes that's better that is 84.1 Jews

21:49

that's good depending on which side you

21:51

play for I think I could actually get

21:53

more than that with a better technique

21:54

and more practice but I take it let's do

21:57

the penetration test for this test and

21:59

also the next ones I'm going to be using

22:01

the black bands the yellow ones keep

22:03

breaking and this perform as well will

22:05

be more durable I also remov the wood

22:07

and the acrylic from the back of the

22:08

fork and installed the new brackets do

22:10

you think it's going to go more or less

22:13

in than the small ones well none of that

22:19

happened oh my god did you see that jeez

22:24

this was the best investment

22:27

ever yo basically bounced on the surface

22:30

of the gelatin and came flying back

22:32

towards me that would have hurt anyways

22:36

before shooting the ballistic dummy I

22:38

tested the damage against of

22:42

Target then I tried with the [ __ ] nut

22:45

and I missed the first shot throwing the

22:47

ball in the air and I have no idea where

22:49

he

22:51

went but with the second shot I got it

22:55

so it's time for the final test damage

22:58

and I really have no idea what to expect

23:01

but I guess let's find

23:05

[Music]

23:08

out oh

23:14

yeah let me show you he went through the

23:17

nose oh my God and he cracked the bomb

23:20

below it do you see that ready so then I

23:23

shot again trying to aim a little higher

23:29

and once again the ammo penetrated and

23:32

it shattered the bone around the eye so

23:34

I want to try to shoot another one on

23:36

the forehead and see what happens and

23:38

well this time I actually hit the

23:44

forehead so I guess this thing is very

23:48

dangerous that was my honest reaction

23:50

while that thing was filling up nothing

23:54

I did nothing now that the liquid is

23:56

gone it's pretty clear to see what

23:58

happened the ammo went straight through

23:59

the forehead and it actually almost came

24:01

out from the back of the head these are

24:04

all the results for the 20 mm lead ball

24:06

and so to answer the question how

24:08

dangerous is a

24:10

slingshot I guess it depends on the

24:12

slingshot I'm going to fix this

24:13

slingshot and paint it and I'll post the

24:15

final version on Instagram follow me

24:17

there if you want to see it along with

24:19

updates on the next videos I'm going to

24:20

keep making cool things like this one so
