Knife switches are very cool. They are usually much bigger. You might recognize them in movies like Frankenstein or Young Frankenstein.

Parts Needed:

• • Rubber band

  • Brad paper fastener

  • Jumbo paper clip

  • Scrap cardboard

Steps:

• 1. Add a rubber band across a brick.

  2. Clip two binder clips to the rubber band and then have them stand up.
