Balloons on the wall

1. My balloons stayed on the wall for more than 2 hours. 2.There is a possibility, because my balloon has stayed up for more than 2 hours. 3. I think that the balloons will eventually fall because the build up of positive and negative charges leak away.

1.A rubbed balloon sticks to a wall because of static electricity 2.The balloons wiill repel because when you rub a balloon on cloth the balloon absorbs the negative charge, and when two balloons have the same charge they repel. 3.Lightning is formed by the water and ice particles in a thundercloud rubbing together which seperates the positive and negative charges, once the buildup of the positive and negative chages become so great, the charges jump between clouds and the ground as a discharge. 5.No a wooden lightning rod wouldn't work because wood is a insulator.
