Bridge building challenge

This week's Think! challenge was to build a bridge using 2 sheets of paper, 6 sticks of spaghetti, 2 spoons, 2 cups for supports, and 15 inches of tape. The bridge was supposed to span 9 inches and hold as many pennies as possible.

Audrey's design used only the cups and tape. It didn't quite span 9 inches, but it held 69 cents.

Mary used the spaghetti inside a folded piece of paper, and used the tape to keep the paper shut and to hold the bridge onto the supports. Stacking pennies on top was like playing "Don't Spill The Beans" so we had to build another contraption to test the bridge. It held 150 pennies before the supports collapsed.
