Meet the Pyro Mini: a wearable system that lets you shoot balls of fire from your hands. Its 2 barrels are filled with flash paper. The built-in trigger lets you shoot fireballs at the push of a button. The rechargeable battery lasts for up to 600 shots.
In Burst Fire mode, you can shoot 2 fireballs at the same time. You can order one of these for under $150 at this time.
