Crafty YouTuber Ivan Owen uploaded a tutorial this week for turning a simple leaf blower into a zombie-killing flamethrower with just some cornstarch.
"Cornstarch! While this is a common cooking ingredient, it can also be flamethrower fuel," explains the Bellingham, Washington, native.
Owen calls his contraption The Conflagulator, and made it by combining a leaf blower, 3D printed parts, and a propane torch.
Bonus: It's very effective in killing zombies.
