Cover this trampoline in three, two,
one. Oh my gosh. This is a car. And this
is a trampoline I designed specifically
to be strong enough to try and bounce a
car, or I guess technically even a boat.
Today, we'll be conducting some
experiments to see what happens when you
drop all sorts of stuff on a steel
trampoline weighing two tons with a mat
made out of Kevlar being held by 144
garage door springs. But to understand
how we even got to this point, we need
to go back 6 months ago when the guys
from the How Ridiculous YouTube channel
issued a challenge. We need to get
someone to help us engineer just an epic
trampoline that can bounce like almost
anything big. And I've got Marky Robber
on mine. And what you need to know about
them is that besides having funny
accents, they do all sorts of crazy
things, usually having to do with
gravity in some form or another. Their
content is always mind-blowing, so you
should subscribe to their channel if you
somehow haven't already. At any rate, a
lot of people seem to think this was a
worthy challenge, including myself. And
so, I got together with my buddy Josh
and first brainstormed ideas. Then, we
did some math. Then, we designed it in
CAD and ran it through a dynamic
analysis and eventually settled on a
design and sent the build plans to one
of their buddies who lives near the
tower. And so a few months later, all
that was left to do was walk to
Australia to meet the guys and check in
on the build.
[Applause]
Wow. The mat is made from Kevlar, which
is the same stuff bulletproof vests are
made of. It's so tough, the only thing
that could cut it to the right shape was
an angle grinder. The garage door
springs can support about 450 lbs a
piece, and we have 144 of them. Like a
thigh master.
They have those in Australia.
[Music]
[Applause]
And so after prepping at the shop, we
made our way to the tower to put it all
together.
