We did the same thing in school one day. we put the tape on the balloon and then took it off when someone was blowing it and it popped right in his face. We got it working after a while and it worked fantastic. It was soo cool! I loved it! Thanks for thinking of this. Can you help me think of an idea to make energy or to show it changing?

The first time it stayed in one spot and spun around in circles. The second time it stayed in one spot and spun around in circles. The third time it finally went 6 feet. It was a real surprise to see it go to the end.

I did the same experiment in science class. I made a glider, using a straw, and attaching wings to it. then I attached that to the string, blew up my balloon, and let it go. It went so far. We raced them, I got second place.
