Can you use a bunch of straws to get two cans to move together?
- 24 straws
- two soda cans
- table
- Try to get the two cans to move toward each other without touching them or blowing directly on them.
Now it's time for you to experiment. Try using ten toothpicks to make six triangles of different sizes. Or, try using ten toothpicks to make twelve triangles. What other patterns can you make? Try it out, then share your results with the world in our fabulous ZOOMsci feedback area.

I connected two straws together twice. Then, I bent them so they looked like a greater than and a less than sign. I blew on the two top ones and the air travelled down the pipe and the cans stered moving toward each other.

When I blew into the straw between the balloon, the cans move together like a magnet! I also did the toothpick one and it also worked. I showed my freinds and now they think I'm a magician.

The cans moved together when I blew between them with another straw.

I saw that when I took one straw from the middle and pushed it, the cans moved toward each other.

My sister and I tried this with yarn and it worked! Then we tried it with a beanie baby and that had worked also! And then we tried it with gloves and guess what? It worked agian! It was fun experimenting.
