My 4th grade son is doing a science fair project using a balloon and wool fabric to demonstrate how the balloon will pick up negative ions from the wool and then picks up positive ions from paper confetti pieces. The results are that the more the balloon is rubbed on the wool the less confetti pieces it will pick up. We used a new balloon each time but the same wool blanket. Did the blanket give up all of it's negative ions eventually or do the atoms get so hyper that they neutralize themselves rubbing on the blanket? We did the experiment 2 times, once rubbing the balloon on the wool blanket 10-100 times increasing by increments of 10. The second experiment was rubbing the balloon on the wool 1-15 times. The results were the same, the more the blanket was rubbed the fewer the confetti it picked up. Can you help us with a conclusion?
