Why does rubbing a balloon on your head make it statically charged?



  1. 0 Votes

    The static cling is an attraction between two objects with different charges, positive (+) and negative (−). You can create static electricity by rubbing one object against another object. The rubbing produces friction which releases negative charges, called electrons, that build up to produce a static charge. When you rub a balloon on your head the friction causes opposite static charges to build up in your hair and in the balloon. You can see these two opposite static charges attracting each other when you pull the balloon slowly away from your head making your hair stand up.
