I don’t know if you’ve seen those videos of people building fire cannons out of two water bottles, but they’re really cool. So cool, in fact, that someone watching one of those videos may decide that they want to try to build one themselves.

If you’re one of those people, you might want to reconsider. Why? Because, as this video shows, an incorrectly built fire cannon can quickly become a pipe bomb.
