Tell your friends that you can make a butter knife float above a table using your incredible mental powers.

Here's how to do it:

1. Put your hand palm-side down over the butter knife.

2. Say a magic word and wiggle your fingers. While your wiggling your fingers, push the butter knife's blade under the strap of your wristwatch.

3. Raise your hand a few inches off the table, and the knife will raise too!
