I Built the World’s Most Dangerous Slingshot

how dangerous do you think is a really

powerful

slingshot you'd be

surprised I definitely was I'm talking

about slingshots that generate more

momentum than a 45 caliber firearm and

I'm not even saying that to be over

dramatic they actually tested it and

finding that out made me pretty upset

because a few weeks ago I made a video

testing a bunch of slingshots trying to

find out how dangerous they are and

while I used to love that video and now

I don't because it's completely

inaccurate all the sling shots I tested

in that video are simply toys compared

to the really powerful ones and so to

redeem myself and actually answer the

question well I'm going to try to build

one of the most powerful slingshots on

the planet a slingshot capable of ending

anything in front of it and behind of it

compare it to the best slingshot of the

previous video and then see what happens

when I test it against a ballistic dummy

this is the Prototype I made for my

custom slingshot and I'm going to

explain the features of each component

as I build them starting from the fork

this is where I'm going to attach

multiple elastic bands and throw massive

steel boss with them and so it needs to

be really tough if while pulling the

bands one of these two pieces broke it

will fly towards me like a bullet and

that my friend might be the end of the

video and the channel sorry Mom well to

avoid that I made a sandwich of

materials that I'm going to glue

together to create the elements of the

slingshot the sandwich has a strong core

to make it tough and for that I could

have used aluminum hardwood or even

steel but I got a lot of polycarbonate

laying around from a previous video and

since it's an incredibly tough material

I decided to go with this

one then I prepared a few thin sheets of

wood and also red acrylic to place on

top of the polycarbonate these are

mainly there for aesthetic reasons and

the effect I would like to obtain is

something like this aim for the Stars

they said anyways to glue the layers

together I'm going to use epoxy

which should work with all the layers of

the sandwich but just to be extra safe

I'm also sending the surfaces of

polycarbonate and acrylic so that the

glue can form a stronger bond with them

so I'm pouring the two components of the

glue into a cup I mix them together for

a while looks like I'm cooking or

something and then I'm spreading it

evenly on each surface of the layers the

problem is that I used way too much

epoxy and now the layers keep sliding on

each others so now I'm panickin while

trying to clamp everything down woring

the layers are going to get stuck in the

wrong position I have to throw

everything away and L another day

starting from scratch but it ended up

working now I got to wait 3 days it's

been 3 days I'm going to remove the

clamps and see if it actually worked had

a few doubts about this one are the

clamps even going to come out and yes

they do kind of two did the epoxy dry

and are the layers fixed in place also

yes it feels pretty solid and three how

strong is the connection between the

layers well either the rising is really

strong or I am really weak but the

reality is that there is not an answer

for this one right now I just got to

hope for the best and see what happens

when I test it the next step is croping

the shape of fork handle and arm brace

out of the sandwich block to do that I'm

using a band saw and after the first cut

I'm happy to see that there is no gap

between the layers which is definitely a

good sign and so I'm training to cut all

the elements following their shapes as

fast as I

can and it took me about 4 minutes but

here they are Fork handle and arm brace

or at least the rough shape of them now

I'm going to use the belt grinder to

smooth out the edges and the surfaces

starting with the fork right now it's

definitely thick but the idea is to

grind it in a way that it's going to

make the pattern come out the problem is

that I massively underestimated this

step and massively overestimated my

skills and after 30 minutes of absolute

random grinding all right I completely

messed up

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

Modern Art and you don't understand it

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

simpler and better one the good news is

that with a spare Fork I can test how

tough it is

yep it's perfect so I prepared new

layers glued them with epoxy waited

cropped smoo in the edges grinded being

extra careful do not mess it up again

and now I'm back to where it stopped

next I'm using this fascinating machine

to smooth the edges and honestly I

started to get pretty excited and this

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

proud now I need to send it then polish

it to make the wood shiny and the

polycarbonate transparent and then I'm

going to do the handle and the arm brace

the same basically the same way I didn't

even finish the fork and I'm already

thinking about when this thing is going

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

to test it before that though I need to

send it and I already know sending is

going to take a while I need to go from

a 2200 GD sandpaper to a th000 grit and

paper so I'm going to just skip this

process but while my slightly younger

self suffers for the next 5 hours I want

to thank this plate for supporting this

project and yes that thing moves I just

finished the workshop and I wanted to

personalize it a little bit so I picked

a few posters and they just arrived and

they looked good from their website but

seeing them in person it actually got me

excited this is

insane it's so cool Spyro I used to play

this with my sister on our PS1 when we

were kids she's about to have a baby

now I love it the posters feel high

quality and sturdy let me try to zoom in

and the clarity on the images is really

good this plate also just launched a new

product called displate Textra which

basically gives extra Clarity to the

images by having a 3D texture on the

posters hanging the posters is also

intuitive and fast and this plate gives

you all the tools you need wipe the wall

stick the protective Leaf stick the

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

but they also have it

flat and that's it basically took me

like 4 minutes to set up three posters

there are over 2 million artworks

available in the displayed catalog and

you can pick from original art or

license design like Star Wars Marvel

Elden ring or Dune I wish I got that one

actually you can also get them right now

by going to display.com shake or use my

prom code M shake and you get a really

nice discount I'm also leaving a link in

description if you want to check them

out at the end of the video anyways 5

hours later the sending was completed

then I used an improvised buffing

machine to polish the polycarbonate and

after grinding a little slot where I'm

going to attach the elastic bands I

finish the fork using Lin seed oil and

wax and here it is I really like how it

turned out but maybe it's just because I

made it kind of like my mom that likes

me regardless well for sure it's better

than the last one it's a so pretty big

this is how it looks compared to a

normal slingshot but it should fit well

the kind of power I'm going for all

right I'm going to make the handle and

the arm brace and so I did it all over

again for the arm brace which luckily

took much less compared to the fork

thanks to the simpler shape and after

sending it this is how it looks now the

last element I need to make is the

handle aside from smooting out the edges

I'm trying to grind the handle to make

it fit perfectly with my hand so I keep

grinding and testing it then I just

adjusting it based on how it feels and

after completing the rough shape I spent

a few hours sending it by hand to smooth

out the curves as much as possible and

as the last step I'm applying the oil as

I did with the previous elements this is

how the final handle looks and I like it

but most importantly it feels very

comfortable and I can't wait to test

this thing like that all the elements

are done now I can put them together

with the main frame and then I'm going

to test it against the targets my custom

slingshot increases the draw length

compared to a normal one basically how

far I can stretch the bands before

releasing them and with more elastic

mass the power increases exponentially

so to connect all the elements together

I'm going to use this steel profile I

need to cut it a little bit first I'm

not exactly sure how long should I make

this Frame though the longer the better

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

just measuring the distance between arm

brace and handle and based on that I

ended up using another profile I had in

the shop this one is exactly 1 M and if

this version ends up being too weak I'm

going to use the longer stick to make an

even more extreme version for that

reason I also want all the elements to

be removable from the main frame and so

to connect them to the frame I thought

about using steel brackets I'm not sure

if this is the best way to do it though

if I making a mistake let me know right

now so that I can stop before this thing

flies towards me when I test

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

I cleaned up the profile using the Bel

grinder and then I I send it by hand

fixing the mistakes I made on the B

grinder one day I'm going to learn how

to use this thing but today is not that

day anyways this is how the steel

profile ended up looking now to connect

the brackets to the frame I'm drilling

three holes of 5 mm into the steel

profile basically like this after that I

can install the brackets in which I'm

going to place the fork I actually also

mounted two brackets at the end of the

seel bar so that this way I can connect

the arm brace to one end of the profile

and the fork to the other through that

though I also need to drill a few holes

into the elements and this step is kind

of scary because the acrylic could

shatter in the process and that would

mean starting from scratch So to avoid

that I'm using a special

bit that should work both with plastic

and wood then I started drilling three

holes into the fork this process took me

like 30 minutes I went very very slow to

avoid damaging the layers and I think it

kind of worked at this point I can

insert the balls that I actually grinded

to make them look nicer and I also added

three rubber spacers since the back of

the wood is not perfectly flat and I

hope this will help distribute the

pressure I think it works yes I believe

it looks pretty good but the best part

is not even the look what surprised me

the most is how premium it feels even

who built it it doesn't wobble at all it

doesn't make noises and it feels very

sturdy now I'm repeating the process to

install the arm brace and this is how it

looks on the profile and seeing it like

that makes me pretty confident this

thing is going to crush

bones hopefully not mine anyways only

the handle is missing at this point and

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

to connect this one and so I'm doing the

first thing I thought about I'm drilling

a big hole into the handle and my plan

is to glue a steel rod into it so that

then I can easily mount it to the frame

to glue the rod I'm using a fast drying

glue that should work well with

polycarb that wasn't a crack it was air

coming out of the handle now there is

one Last Detail I need to add to the

handle the bols on the fork and the arm

brace basically act as spins providing

extra strength to keep the layers

together and since the handle doesn't

have those I decided to add four small

bols to it they don't compromise the

comfort and this way I'm sure the layers

are going to stay together even if I

drop it and to mention the words of a

wise German man I'm going to introduce

in a bit it's not ugly

it's effective now I'm mounting the

handle using a piece of ladder to

distribute the stress between the handle

and the frame and like that the custom

slingshot is ready I really believe this

could be up there with the most powerful

slingshots in the world but I guess I'm

going to find out soon when I test it I

don't know if I should be excited or

scared I'm excited though but the reason

why I picked this design over some

crazier ones ahead is pretty fascinating

it looks fairly simple but this design

should be the most powerful one you can

make for a handeld slingshot and the

reason why I know that is this man hello

and welcome to the slingshot Channel

while checking the comments in my

previous slingshot video I saw this one

that threw me right into the rabbit hole

that actually made me start this project

yorg is a German God right on top of the

slingshot foot chain and he set a world

record of 135 ju with a 25 mm steel ball

and just to clarify 135 ju is closer to

a small firearm in terms of power than

it is to a normal slingshot and since I

don't have much experience with

slingshots and most importantly I'm not

German I reached out to him and he

actually replied yor gave me a lot of

valuable information that allowed me to

get to this point and most importantly

he made me realize that there is a

serious risk involved in what I'm about

to do and he also suggested me to scrap

all my other designs besides this one I

build and it's basically a new version

of the Starship which is the slingshot

he used to set the word record and so

now I can install the bands and then I'm

going to test it the size and the number

of layers you need depends on the weight

of the ammo you're using heavier ammo

require more bands which are much harder

to pull but they also generate more

power so to find out the dimensions of

the Bands they need for all the bosss

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

that York created basically based on the

weight of the ammo you use and the draw

length it TS you the dimension and the

number of bands you need and to find my

draw length I measured my draw length

with a normal slingshot have no idea if

this is the right way to do it and I

added the extra length of the frame with

that I got a total of 198 CM which is a

lot but I'm using a smaller one to be

conservative for maximum performance

bands also need to be tapered basically

they need to be larger towards the fork

and smaller towards the pouch this

allows the ammo to accelerate faster and

therefore increase the speed and the

power after that I can attach the bands

to the pouch and the process is pretty

straightforward little bit spit for the

most part of it Al the friction causes

not to get all messed up and you can

actually just break the and here is how

they look at this point I can attach the

bands to the slingshot and like that the

build is finally

completed it's ready and so now there is

only the fun and potentially little step

left all right then let's test it now

before risking my life with a massive

balls I want to find out if my custom

slingshot well if you works and also if

it's actually more powerful than the

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

going to gradually increase the

dimension of the ammo and the number of

bands and I'm going to measure energy

penetration and damage for each one of

them I feel like a

juggernaut I know you're probably

thinking it's maybe too much for this

small ammo I'm actually worried it's not

going to be

enough but I guess there is only one way

to find out

and well it turns out that this thing

works pretty well 125 yeah it's fast out

of five shots the best one I got is 130

m a second or 426 ft per second and if

you consider that a 9 mm bullet travels

at around 1200 ft per second that's a

lot so with the 8 mm seal bar the custom

slingshot generates 1.6 times more

energy than my best sold one this is the

weakest set up I'm going to test and it

already broke the catch boox behind the

wooden panel I also tested a different

brand of rubber but I got very similar

results so now it's time for the second

test with the 8 mm

ball penetration and at my first shot

the ball went on the side of the gelatin

block and I actually thought it was a

fluke no cuz it went way too deep oh no

way jeez but then when he tried

again the second shot was perfectly in

the middle and he went deeper than the

first if we compare the penetration of

my old slingshots compared to this one

this is insane the old slingshots are

also not lethal with an 8 mm Ball but

given this

penetration do you think it's going to

be lethal 8 mm ball test number three

damage and so I stretched the bands as

much as I could and I

shot no way at first I thought the ball

actually cracked the skull but then then

I saw it it stopped the ball went into

the gelatin but it stopped on the

skull let's keep it there also what's

wrong with your nose man J I didn't

notice that anyways this slingshot is

already more impressive than the ones I

tested in my old video and this is

literally the weakest possible setup I

have for this one so I'm very curious to

see what's going to happen with the big

balls but in the meantime these are all

the result I got with the smallest one

next I'm shooting 10 mm steel balls and

to shoot them I'm going to use a double

layer setup basically two bands per side

and I was expecting the 10 mm BS to be

significantly slower compared to the

previous ones but the

speed actually didn't drop very much 11

19.1 that's a lot out of five shots the

best one I got was

124.401 in bigger boss to have less

penetration

power

but it almost went through with a 10 mm

steel ball I got a penetration of 13.9

CM before trying the ballistic dummy I

also want to shoot a few different

targets this is not part of the official

test and I could totally avoid it but I

won so I shot a

watermelon then a coconut which is

pretty hard but it still went straight

through and then a sakan

and at this point I'm kind of thinking

this might be lethal already all

right nope wait what is

that that was

anticlimactic I'm not exactly sure if he

bounced on the bone or he just went

straight there either way I'm going to

try again aiming at the forehead

oh no way went once again perfectly

inside the eye in the other

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

again but once again it didn't crack so

I think the bosss were just bouncing off

the bones anyways these are all the

results I got for the 10 mm steel

balls and now it gets scary 20 mm lead

bosss like these are the bands I just

used and these are the bands I'm going

to use now three huge flat bands per

side and for this one I also had to

build a bigger pouch I'm scared for the

first time since I started testing this

thing now I'm actually scared as a

disclaimer I don't think this is wise I

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

think it's going to be enjoyable to use

a monster like that but I just want to

go for it this is how it looks with the

flat bands connected to it and with that

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

expected these bands are way harder to

pull compared to the previous ones but

even though this setup highlights my for

technique and the lead ball actively

tried to kill me it was actually working

pretty well how much was

that 57.9 and that means 79.3 Jew of

energy which is a lot still I wanted to

keep trying for two reasons first

because I know I can top my previous

speed I just need to develop a slightly

decent technique and build up confidence

and second because I'm kind of loving

the distraction this thing is able to

generate and I can't wait to test it

against the targets but then I made a

mistake somebody said that if you run

when you can't

walk you'll probably fall and that was

the sound of the steel ball here in the

fork I broke

it

yeah [ __ ] it

I broke the fork that's a bad one this

has been a very unfortunate turn of

events I got an allergy reaction it's

pouring and it wasn't even supposed to

rain my slingshot

broke on the other side though I'm still

alive and most importantly though the

polycarbonate is very tough indeed it

doesn't even have a scratch on it and so

I found a temporary fix so that I can

keep using it you know it is what it is

it just lived long enough to become the

villain so I'm going to just wait for

the Sun and then I'm going to finish the

test how's it going guys today's

tomorrow and sunshines now you know why

that happened by watching the slow

motion of the incident I realized that I

pushed down my hand right before

releasing the pouch and well I just got

to try avoid doing that again I also

just built a much deeper armrest since

the helmet sticking out made it kind of

hard to stretch the BS comfortably all

right then let's see what happens I'm

going to just try to stretch this as

much as I can so if you hear weird

noises that's why and so I wanted to

measure the energy once again and after

shooting at the Target a few times I

actually topped the previous result 59.6

59.6 yes that's better that is 84.1 Jews

that's good depending on which side you

play for I think I could actually get

more than that with a better technique

and more practice but I take it let's do

the penetration test for this test and

also the next ones I'm going to be using

the black bands the yellow ones keep

breaking and this perform as well will

be more durable I also remov the wood

and the acrylic from the back of the

fork and installed the new brackets do

you think it's going to go more or less

in than the small ones well none of that

happened oh my god did you see that jeez

this was the best investment

ever yo basically bounced on the surface

of the gelatin and came flying back

towards me that would have hurt anyways

before shooting the ballistic dummy I

tested the damage against of

Target then I tried with the [ __ ] nut

and I missed the first shot throwing the

ball in the air and I have no idea where

he

went but with the second shot I got it

so it's time for the final test damage

and I really have no idea what to expect

but I guess let's find

[Music]

out oh

yeah let me show you he went through the

nose oh my God and he cracked the bomb

below it do you see that ready so then I

shot again trying to aim a little higher

and once again the ammo penetrated and

it shattered the bone around the eye so

I want to try to shoot another one on

the forehead and see what happens and

well this time I actually hit the

forehead so I guess this thing is very

dangerous that was my honest reaction

while that thing was filling up nothing

I did nothing now that the liquid is

gone it's pretty clear to see what

happened the ammo went straight through

the forehead and it actually almost came

out from the back of the head these are

all the results for the 20 mm lead ball

and so to answer the question how

dangerous is a

slingshot I guess it depends on the

slingshot I'm going to fix this

slingshot and paint it and I'll post the

final version on Instagram follow me

there if you want to see it along with

updates on the next videos I'm going to

keep making cool things like this one so
