It turns out, selling unlicensed nuclear accelerators is kind of against the law, not to mention highly irresponsible. Someone out there would definitely end up crossing streams just to see what happens. So, for those reasons we've just decided to bring you this stylish Proton Pack backpack, licensed from the Ghostbusters. It doesn't fight ghosts as well, but it also won't inadvertently make all of life stop instantaneously, or make every molecule in your body explode at the speed of light.
