3D3DBeer foaming ball.
It never ceases to amaze me what a crazy world we live in, and here is more proof. This is a small hollow plastic ball, kind of like a pingpoing ball, except you buy it inside a can of beer. The idea is as follows. The ball has a tiny hole in it and is filled with compressed nitrogen. The nitrogen doesn't escape because the whole can is pressurized, and it doesn't fill with beer because the hole is very small, so surface tension keeps the beer outside and the compressed nitrogen inside. Until, of course, you open the beer can, at which point the external pressure is removed and the nitrogen starts squirting out of the tiny hole. This creates foam in the beer, giving it a "head" just as if it had come from a tap or keg.

Oh come on people, why not just give up, the stuff tastes like piss whether or not it's got gas injected into it seconds before consumption.
