If you mess with science you may find yourself on the wrong end of a laser beam designed to burn right through whatever gets in its way and powerful enough to shoot through a computer case.
So be nice to Drake Anthony (aka styropro) if you ever meet him, because he built a 200-watt laser bazooka out of "scrap metal, a pile of broken ‘hybrid’ DLP projectors, and runs on a stack of lithium polymer batteries" and he ain't afraid to use it.
