Not just a weapon seen in science-fiction movies anymore, this homemade pulse laser gun actually works. Its creator says that just “one shot can punch through a razor blade, plastic, 5mm styrofoam when focused.” Video after the break. Click here for more pictures.

Effective range on 3m (dark surfaces)…you will see a stinging flame and a 5mm stain will remain on target. The goal was, to create handheld device…AS COMPACT as possible. Its 320mm long and weights about 2 pounds.
