On Thursday night we had the Iolani Fair 2011 kick-off meeting! Before the festivities began, our executive committee helped out with decorating the student center. One of our jobs was to tie the balloons together and attach them to the tables. We also got to play with some of the balloons ;D. Scott kept trying to make people’s hair stand up by rubbing the balloon against their hair and pulling the balloon away. Now, how on earth does this all relate to physics?!? Well, in physics we’ve been learning about charge and static electricity. When Scott rubbed the balloon against my head, he was creating a charge by friction. Also, when he tried to stick the balloon to someone, only the rubbed side would stick because rubber is an insulator and does not conduct electricity well. Due to this trait, the electrons remained concentrated on one side of the balloon.
