I wonder what would happen to someone actually using it.
On Booth’s website are videos showing how each amusingly-named weapon (think “Chucks of Liberty” and “Blunderbussiness Class”) was made. For example, the shotgun is powered by lithium metal batteries. Combine them with water and the resulting chemical reaction will cause a bottle of Axe body spray to explode, shooting a bunch of pocket change with enough power to penetrate drywall. The grenade/bomb also uses the Axe-battery-water combo, plus a stainless steel coffee tumbler and a condom, and can be put together in less than 10 minutes, Business Insider reports. Booth sends all his findings to the Department of Homeland Security, and he’s gotten the attention of the FBI, which questioned him as part of a report it’s putting together but wouldn’t help him out: “It would have been awesome,” Booth says, “if I’d had access to, like, a cockpit door.”
