Impressive…  Take a handful of fat capacitors (probably 500uF to 800uF each) and hook them up to an electromagnetic coil; make a stylish weapon.  Now, typical muzzle velocity of a handgun is about 1200km/h, whereas this gun only fires at 110km/h; so it won’t kill you, but it’ll hurt like Hell.  By the way, real rail-gun supposedly fires aluminum projectiles at relativistic speeds (near speed of light), which is why you only see them in science fiction.

Rail Gun

Daniel Eindhoven is talented designer who created this  cool  coil  gun. It took around 40 hours to finish this outstanding job. It weights 5 Kg and, capable of delivering over 18J kinetic energy, and speeds up to 110km/h . This  weird coil gun has  laser pointer for easy aiming and it costs around 100 Euros.It needs 8 seconds to fire a projectile if is connected to  power source or 90 seconds with batteries. It is really impressive, I’m not a gun lover but this one is really made with creativity. You may also would like to check this Swiss mini gun, the smallest gun in the world.
