Anna of Houston, TX

You'll huff and you'll puff and you'll blow across the finish line!

Materials Needed

  • non-bending plastic drinking straws
  • wintergreen or peppermint lifesavers
  • paper
  • paper clips
  • tape
  • scissors



  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.

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.
