Make a balloon as hard-headed as you are.

Materials Needed

  • water balloons
  • soft and protective materials
  • tape



  1. Check with a grown-up before you begin.
  2. Protect your balloon like you do your brain. Make a skull for your balloon with soft and protective materials.
  3. The ZOOMers used materials like Styrofoam, cotton, cloth, tissue, felt, egg cartons, bubble wrap, newspaper and tape. You can use anything you like, just make sure that part of your balloon is left uncovered.
  4. Have a friend make her own skull so that you can compare your designs.
  5. Now test out your Balloon Brain skulls by throwing them against a wall. You'll need to do your testing outside or somewhere that can get wet in case your balloons break.

Which materials were the best at protecting the balloons? Which were the worst? What combination of materials worked best? What is it about these materials that made them better or worse than others? send your discoveries to ZOOM!

First, I got a plastic bottle with soda, and I got a balloon. After I get my suplies I put the balloon on the plastic soda can. When you shake the soda the balloon will start filling up with gas, and will cause the balloon to fly, because the gas from the soda will go in the balloon. The gas causes the balloon to fly, because it is lighter than air.

When I tried the Balloon Brain expirement something amazing happened. It wouldn't pop. First I covered the balloon in a half an inch thick layer of napkins. Then I used about 15 cotton balls on the balloon. Then I used bubblerap. After that it was all done. When I threw it against the wall it didn't pop. Then I just kept on throwing it. I was amazed to see that I can throw it three times without poping it. Do you think you can beat that.

The balloon had popped when I had hit it against the wall three times. I tried it again with different materials like cotton bolls and bubble wrap and it didnt pop until the tenth time. That design worked a lot better.

When I threw mine againest the wall it did not brake. But when my friend and I switched when she threw it and then hit the floor it poped then. But other wise mine "skull" was a very "hard".
