Backyard RAILGUN: Field Testing the 250 lb Electric Gun, 27,000 Joule (max)

This is the first test of the railgun. Launches at 27,000 joules are shown in my other videos with improved cable connections. The newly built railgun is field tested at 20,500 joules. It is the first mobile, shoulder mounted railgun. *****DO NOT TRY THIS AT HOME***** Notes: A railgun uses current to generate extreme magnetic fields that propel a conductive projectile to high speeds (iron is a poor conductor and therefore unsuitable). Aluminum has been the universal projectile choice for its low melting
