Question

Move the balloon very close to the wall, but don't touch the wall. Then let go. What happens to the balloon?

Answer 1

The electrons in the wall repel because of the negatively charged balloon, exposing the positively charged nucleus, allowing the balloon and wall to attract each other. (Electrons repel to the back of the wall).

Answer 2

it lets out the air inside the balloon and I´m pretty sure it would hit the wall while the air was being let out.
