  • table

Instructions

Instructions


  1. 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.

My brother and I were doing it and we had read what the instructions said and so my brother did it that way. Then I set my can onto a few straws and saved one then blew through the straw to make the straws move and then the cans drifted toward each other like they were in water AMAZING!!!

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.
