Tools and Materials

The Engineering Creation Kit has everything you need for this project and many more from STEM Inventions, or get the supplies in bulk:

• Hot glue gun

• Glue sticks

• Masking tape

• Craft sticks

• 1/2" craft cubes

• 3-1/2" rubber bands

• Clothespin

• Tool for cutting corks

• Foam cubes (for projectiles)

Tips and Troubleshooting

If the launcher isn't shooting very far, then...

• Make sure the rubber bands are being stretched out enough.

• Make sure the clothespin is positioned at the top of the craft stick "stairs." If it's not, the cork or the rubber band may get caught on the edge of a stick.
