What do you do if hungry raccoons are tearing your garbage to shreds every night? You can put locks on your cans, or if you’re YouTube’s The Backyard Scientist, you build a gigantic mouse trap with a spring-powered, coconut-smashing arm that reaches speeds of 42 miles per hour.

Its spring-powered mechanism is so powerful that an electric winch is needed to tighten the coil. Of course, trying to prime this trap manually is far more terrifying than just running outside in the middle of the night and fighting off a posse of raccoons, so maybe just stick to that.
