Testing a square catapult

Toys may be made primarily for kids, but the tools used to make them are not. Hot glue can burn and tools should be handled with adult supervision as some are sharp and can damage people and property. Don't shoot these launchers at people, animals or anything but the recommended targets. Plastic cups don't bleed. parents: watch with your kids and if these projects interest, do them with your kids. This Channel is not your babysitter.
