Inspired by Iron Man, Patrick Priebe built his own palm-mounted laser. It apparently uses a 1,000 miliwatt, 445nm laser diode. That ain't no laser pointer. From MSNBC:
That laser is among the most powerful you can buy commercially, and it is capable of blinding instantly and setting fire to skin. Fortunately, the palm mount is made from a 2mm-thick sheet of brass, which acts as a heatsink that protects the wearer.
"DIY palm-mounted laser is ridiculously dangerous" (Thanks, Jacques Vallée!)
