Ok, so, you're probably like me in that you've always wanted to be able to jump around like a moron, like you were on the moon.
I propose to make this fantasy a reality, using cheap materials and simple physics equations. That diagram pretty much explains everything.
Everything except where I'm going to get 2144 cubic feet of helium.
Each of those helium tanks that you can rent for parties carries about 150 cubic feet of helium. It's something like 20 cents per cubic foot. That would be nearly 430 bucks plus the deposit for 15 of those party canisters (usually 150 bucks a piece). Hilariously impractical because of the 2700 bucks in out-of-pocket cost, and also because I dont have a vehicle capable of carrying 15 huge canisters of helium gas.
There has to be a way to buy helium in bulk. And in liquid form for easy transport.
