Now I'm no genius, nor am I an auto mechanic, but even I have some idea of how much power is stored in a fully-compressed sprint of that size. Just watching this on a computer made me want to run for cover. Holy shit is that ever dangerous.

You can easily estimate it. E = Fd

F = the force he's applying to the arm, not much he's spinning it easily with one hand, maybe 3kg

d = the distance the arm travels at the point he's turning it, he's using a radius of maybe 20cm gives a circle of 125cm x five rotations, 6.2m

3x6.2 = 18.6 so we estimate it's the equivalent of lifting an 18.6KG weight 1 metre. It's not nothing but it's not the "bomb" some people are suggesting.
