A straw bridge that's crazy.
- straws galore
- paper clips
- something to test its strength (try pennies, but not your cat)
- Build the craziest designed bridge using only straws and paper clips that can span 30 centimeters and support the most weight. You first have to think of a plan of how you are going to build your structure. Dani gave us a clue: triangles are very strong.

Hi, I have instructions for you. You need 21 straws, 2 rubber bands, and tape. You attach the straws together with rubber bands and tape. I tested it with a plastic ball.

When I did the crazy straw bridge I put a quarter on it and it stayed for a long time. It stayed from 6:AM to 12:AM. It is sure a crazy straw bridge. It is crazy, a straw and a bridge that is why it is called a crazystrawbridge and that is all I have to say.
