Activity

Make a levitating orb

PurposeIt is all about static charges. Similar static charges repel away from each other. When you rub the pipe in your hair you give the pipe a negative static charge. The orb is attracted to the pipe at first because the orb has a positive charge. As soon as the orb touches the pipe, it picks up a negative charge. Since the pipe 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. Did you notice the orb is attracted to other objects around you – including you? That is because most objects (including you) have a positive charge.

The Experiment

To make it a true experiment, you can try to answer these questions:

  1. Does the number of mylar strands affect how well the orb levitates?
  2. Do different materials (hair, fur, wool) build up better static charges?
  3. How long does the static charge last / how can you make it last longer?
  4. Do different widths of pipe affect the floating ability of the orb?
Materials
  • 1 inch (2.5 cm) wide PVC Pipe about 24 inches (60cm) long. You can also use a regular balloon if you do not have PVC pipe.
  • Mylar tinsel for Christmas trees. There are many types of tinsel and many will not work – you should look for the thinnest and narrowest possible. The tinsel used in the video is about 1 millimeter wide. If it is much wider than that, the orb may be too heavy to levitate. (You can order it HERE.)
  • A head of clean, dry hair OR fur or wool.
  • Scissors
