My preschooler loved this! If the charge starts to fade, simply rub the balloon in your hair again and it’s ready to make your wings flutter all over again. It was a little difficult to get great pictures of the butterfly in action because my daughter moved so quickly.
Results: Why did the butterfly wings move?
When we rubbed the balloon onto our hair, electrons were lost from our hair and gained by the balloon giving it a static charge. When the negatively charged balloon gets close to the positively charged tissue paper they are attracted to each other, and the pull of attraction is so great that the lightweight tissue paper moves toward the balloon.
