A class 1 lever puts effort on one end, the work on the other, and the fulcrum somewhere in between.
This project illustrates this fundamental tool while also delivering some high-flying projectiles!
Tools and Materials
- 1/2" craft cubes
- Cubes with holes
- Plastic portion cup
- Tool to cut or break craft sticks
Tips and Troubleshooting
If the hinge is breaking or falling out of the cubes, then...
- Make sure to press firmly and quickly onto the catapult arm; don't strike it with your fist
- Make the dowel slightly longer so it can't fall out from between the cubes with holes
