When an insulator rubs against another material, it can cause electrons to be transferred from one material to the other due to the contact and separation forces. This results in one material becoming positively charged and the other becoming negatively charged. Friction between the insulator and another material can create an imbalance of electrons on the insulator's surface, leading to the insulator becoming charged.

If you put a dented ping pong ball in ice water, the cold temperature may cause the air inside the ball to contract, intensifying the dent. Additionally, the change in temperature can affect the elasticity of the ping pong ball material, potentially making the dent more permanent.
Yes, bees can see ultraviolet light. Their eyes are sensitive to ultraviolet wavelengths, allowing them to see patterns on flowers that are invisible to humans. This ability helps bees navigate to food sources more effectively.
