Electrostatic energy
Explanation:
We can see tiny sparks of light and hear a crackling sound when we take off a woolen sweater or a polyester shirt due to the formation of static electricity. Electrostatic energy is created when the balloon rubs against the wall. This is a phenomenon called charging by friction. It happens because the balloon gets charged due to friction between the balloon and the wall.
