6. Static Electric Straw Trick
Materials: the cotton t-shirt you’re wearing, a plastic straw, and a full, plastic water or soda bottle
Preparation: Rub the straw into your shirt till it becomes static electrically charged.
Trick: Place the straw horizontally onto the top of your bottle’s lid, give it a slight nudge (without knocking it off), and the straw should move from side to side without any further nudging.
