Wow, this guy is awesome. He sounds a lot like Louis C.K. and it blows my mind that this guy just went off at the drop of a hat like that. So great.

The world's most useless machine.

Haha, this guy...youtube comment said:Why build a self-defeating machine like this? Its only purpose is to self-terminate. Is it supposed to be a metaphor for existentialism?
Way too much free time.

should've read the infoShould've used a smaller projectile.
Q: Will a smaller projectile result in better efficiency?
A: No, a smaller projectile won't be able to absorb as much magnetic flux as a larger projectile, due to a phenomenon known as magnetic saturation (Wikipedia it!)

http://www.instructables.com/id/Coil-Gun-Projectiles/Projectile Mass
Lower Mass projectiles will travel faster as KE=1/2mV^2. Unfortunately the material must be a ferrous/ferromagnetic one and so the weight is fairly set per unit volume. The mass is needed as it is the magnetisable mass that the coil gun uses to attract the projectile into the coil. If the projectile is too small the iron will ”saturate” meaning it is entirely magnetised and if a larger core was used more material could potentially be magnetised. Optimally, the coil gun should not saturate the projectile but come infinitely close to doing so.
