Bridge challenge

Supplies

2 pieces of paper

4 paper clips

4 safety pins

4 popsicle sticks

6 bendable straws

appx. 22 in. of masking tape

50-100 pennies

 

The way they did it was that the bridge had to be at least 22 in. long to qualify.  They used math cubes as the support beams on each end to measure every bridge (to make sure it was long enough).  Only the edges of the bridge could touch the support beams, and no part of the bridge could touch the table.
