A bendy straw can make any balloon spin.
- bendy straws
- rubber bands
- First, cut about two inches off the bottom of the bendy straw.
- Next, blow up a balloon. Put the opening of the balloon around the bottom of the straw. Hold onto the balloon and straw so that you don't let any air out.
- While holding the balloon and straw, wrap a rubber band around the balloon so that the balloon stays in place.
- Then, bend the top of the straw, put the balloon on the table, let it go, and watch what happens.
In order for the air to get out of the balloon, the air has to turn the corner in the bendy straw. When the air turns the corner, it pushes on the straw and the straw pushes back on the air. The straw then pushes on the balloon and look what happens to the balloon. What do you think will happen if you change the direction that the straw points? Experiment, then send your results to ZOOM!

First the balloon went counterclockwise, then clockwise, then counterclockwise, and so on an so forth, until it ran out of air.

I put a string through the straw and taped the string to the white board where I had drawn a bull's eye. I blew up the balloon and taped it to the straw. When I let go of the balloon, it shot accross the room. I did this twice and it worked both times. It went about 14 feet.

The balloon was hard to blow up, it hurt my cheeks. when I let it go it spin in a circle really fast and as it got smaller it moved faster. When I changed the direction of the straw it went in the opposite direction.
