Was it summer or winter there? 😮 Ir seem to be very cold summers over there.

nice video bro

Incredible! What an amazing machine!

I'll disappoint you, but it's not a trebuchet.

Do you have the design plans for the full system? I'd like to take the plans and modify them for tennis balls for scouts.

That supersonic device is legally, a FIREARM. Any device that launches a projectile with a "muzzle velocity" in excess of 500' per second, is by definition, a FIREARM. At 400 meters per second, and with my very ruff arithmetic, it is moving at around 1312 feet per second, which is ruffly almost twice as fast as the speed of sound, and well above the 500 feet per second limit before becoming a FIREARM. I don't know if that matters in the USA cuz most folks there are legally allowed to own firearms anyway but it makes a huge difference up here in Canada. I am sure that Turdope would have a huge problem with anyone making and/or owning any size of siege-weapon and considering that his Parliament Buildings are made of giant boulders, which was built in or about 1867, I would think that that arrogant little sock boy would have a huge problem with a siege weapon that specialized in knocking down buildings like that in a few hits. Nobody without some kind of really fancy licence would get that weapon clearance in anywhere but the remotest of locations. And never anywhere near where Turdope works.

Well Done! Now work on targeting accuracy.

Since you use elastic instead of counterweight could we say that this is closer to a catapult than a trebuchet ? Just asking.

The safety issues you mention in the description made me skip a beat while watching the video, glad you pointed them out.

Would love to see more videos from you. I hope you are alright. I've learned a ridiculous amount from this video.

Amazing stuff dude

How far can it through a projectile?

Impressive but this is not a trebuchet. This is a torsion catapult.

you can also break the sound barrier by hand, with a whip

I'm so glad there are people out there much smarter than me! lol. Thank you.

very well done bro

This is flipping awesome… I’m keen to try and replicate this project myself!

@WarpedPerception or @theslomoguys have cameras high speed enough for capturing this.

I need something bigger than that to take over Panama

Put a 12 volt car starter for winning it up.

You got the speed, now you need payload. For a trebuchet, payload is everything!!

Of course the show must go on. It's time for a hypersonic rubber band powered trebuchet.

Weirdly this reminds me of PUBG...

13:34 - 13:36 sounds like the Sonic Booms

Great, very interesting.

Respect the engineer!

That's 894.77 mph! The speed of sound is about 767 mph.

Well done.

One of the best videos on KZbin.

What you need is more brain

Jesus.

One video and you've caught the eyes of a solid half-dozen of my favourite creators! I imagine your capacities are better spent offline but should you return to KZbin there are thousands of nerds eagerly awaiting your next project!!

0:10 Oh, yes. Knex. Very dangerous before gunpowder.

Ahh, good ol knex. I remember building powerful rubber band powered guns out of these in my early to mid teen years. My best design was an almost 5 foot long rifle that was powered by those massive and thick rubber bands you frequently see holding broccoli together. To withstand the extreme force of these bands, it was rather chunky and had four "pistons" rather than just one to reinforce it which pulled the launch rod along with it. It fired the medium sized yellow rods with fletchings added to them out of tape. To cock the thing I originally had a rotating crank ratchet system which I later upgraded to use two knex motors to crank it back for me. It could fire all the way across my yard which was pretty big, probably about 400-500 feet long. Your design is absolutely badass! Keep it up!

Holy shit, I wonder what it sounds like downrange hearing the projectile go past Any way you could get a drone up there?

Now all you need is a castle to knock down.

iu klove yoiu

Safety glasses. Safety glasses. Safety glasses.

Big difference between a trebuchet and a catapult. Better look that up.

That is amazing...

oh wow its been 3 years already

Among the more useful guides on youtube, I couldn't find anything else on the web explaining how to build my supersonic trebuchet.

my dude made this over the course of 6 months

What was the weight of the ball?

imagine this thing scaled up to throw a cannonball or bolling ball it would be insane

weakest dwarven weapon

This video really shows difference between proper engineering graduate and people just playing around to get views

I tell you what, I wouldn't be standing right in front of that thing as I load it, I'd stand to the side

Your autistic presentation style reminds me of Paul Harrell.

Now make it hypersonic
