Feel like a waterbender!
Warning! Only under adult supervision.
Fill a measuring syringe with water and suspend it above a bowl. Rub a balloon on your hair and pull the plunger out of the syringe – the water will begin to pour out in a thin stream. By bringing the balloon to the jet, you can change the path of the water!
When you rub the balloon against your hair, electrons are transferred to the surface of the balloon, giving it a negative charge. The electrons in the jet of water are displaced away from the balloon, while the protons, conversely, are attracted to it. The strength of any electrical interaction is inversely related to the distance between the charged particles. Therefore, the redistribution of charges leads to the attraction of the jet to the balloon.
