1. Cut a small hole big enough for your finger to fit through in the bottom of a box.

2. Fill the box with cotton so your friends won't see the hole when the box is open.

3. Poke your finger through the hole in the bottom of the box, and lay it on the cotton.

4. Put the lid on the box, and tell your friends you have a mummy finger in the box.

5. Take off the lid and reveal the mummified finger to your friends. Wiggle your finger slightly and act surprised. Maybe it is coming back to life!

If you want to look even more convincing, dust your finger with powder to make it look old.
