A quiet balloon. Rub it, then bring it to the wall.
Why did the balloon stick?
A quiet balloon. The wall is just a wall.
Rub the balloon, then bring it to the wall.
Plus and minus marks are a map of leftover charge. They are not stickers. The wall is not a magnet.
The balloon stuck to the wall. What held it there?
You can try this.
Notice
After rubbing, bits of hair or wool lift toward the balloon.
Without rubbing, the balloon does not stay.
The wall did not become a magnet. Something else moved.
What do you predict?
If you rub the balloon, then bring it to the wall, will it hold?
