Rotate the Straw Without Touching That
1.plastic drinking straw.
2. A Bottle
1. You need a plastic drinking straw and a bottle with the lid screwed on.
2. Secretly rub the straw against your shirt or in your hair (as long as it's clean)
3. Balance the straw on the lid of the bottle.
4. Bring your finger close to the end of the straw that you rubbed on your shirt or hair. The straw will be magically attracted to your finger.
5. Move your finger to the other side of the straw and it will rotate in the opposite direction. Spooky!
