Question: Why do the lifesavers spark?
Answers
Question 1: Lightning
Question 2: By rubbing the balloon, you're covering it with lots of little negative charges. The negative charges are attracted to positive charges in the wall. In fact, they're so attracted they will hold the balloon against the wall.
Question 3: When you break the candy apart, you're breaking apart sugars inside the candy. The sugars release little electrical charges into the air. These charges attract oppositely charged nitrogen in the air. When the two meet, they react in a tiny spark that you can see.
