Still taking down that Christmas tree? Well we've got an excellent use for that old tinsel- make levitating orbs with your mentee!

The key here is static charge. Similar static charges repel away from each other. When you rub the pipe/balloon in your hair you give the pipe/balloon a negative static charge. The orb is attracted to the pipe/balloon at first because the orb has a positive charge. As soon as the orb touches the pipe/balloon, it picks up a negative charge. Since the pipe/balloon is negative and the tinsel orb is now negative, they repel away from each other and the orb levitates! The orb will also take on more of a “ball” appearance when charged since all the tinsel strands are repelling away from each other. This is one science trick mentees of all ages are sure to love!
