  1. Check with a grown-up before you begin.
  2. To make your Puff-mobile, you can only use straws, lifesavers, paper, paper clips and tape.
  3. To make your Puff-mobile go, you can only use your breath.
  4. Have your friends design and make their own Puff-mobiles, then have a Puff-mobile competition. Can you get your Puff-mobile to move 9 feet? See who can move their Puff-mobile 9 feet with the fewest number of breaths.


Which Puff-mobile design crossed the finish line first? What about the design made it better? Write to ZOOM with your race results.

What happen was that we tried out different ideas and we finally got one. After that we put the sales on with the paper clips. Next we started racing the original desings and we got in 2nd place on the championships and our car was juts zooming past the other ones but we are doing a rematch. Finally if I could change a thing I would put a sale under the puff mobil so it would go fasterbecause we have to blow under our car. And I was thinking that if we added a sale under it would go faster.

I made my puff-mobile out of paper, tape, and straws. Although it has to be on tile, wood, or other smooth surfaces, it goes really fast! It can't move on carpet. I made a sail out of cut up computer paper and straws. I also curved the edges of the paper up.

I got one sheet of blue card stock and folded it by one corner into a triangle. Then I put a paper clip at the nose and cut the top off. My brothe Eric did the same thing to his but didn't cut the top off. It took me 13 puffs to get it 9ft it took eric 20 puffs.
