The Pyro Handheld Fireshooter is ***supposed*** to be for magicians, but I can’t imagine everyone not wanting one. This very real, very crazy gadget sits on the underside of your wrists where it can be hidden by a sleeve. The gag is activated by a remote switch you hide in your other hand, and can be fired up to four times without reloading.
The video shows using the gear in the wilderness, but I’m thinking Times Square would be fun. Near one of those weird Plushie guys.
