-Backyard Rail Gun-
A rail gun utilizes electric current to generate extreme magnetic fields to propel or fire highly conductive and suitable projectiles at extreme rates of speed.
Believe it or not iron is actually not a great conductor. The more suitable choice for a rail gun projectile is aluminum.
Aluminum is great because of it’s high boiling point, low mass and high conductivity.
The flash of sparks you see upon firing is a good sign as the projectile is meant to glide along the rails and melt causing less friction and a smoother trajectory.
This is very cool to watch but is a sketchy set up and I wouldn’t recommend this be tried at home. They do make some nice upgrades to the gun and shoot a projectile into a convertible saturn.
