We made popsicle stick bridges at work with the kiddos. To declare a winner, each bridge had to go through 3 rounds of vigorous testing. Round 1: 4 dictionaries. Round 2: 4 dictionaries plus ALL SEVEN Harry Potter books...hardback. Round 3: Miss Christine.
My job was to balance all of these books on the 6 inch long bridges by holding one of the dictionaries vertical and simultaneously balancing the other books on top. SORE BACK
In the third round, my job was to stand on the bridges.

Finally, after one bridge did not snap to bits under my weight, I declared to the class, "Jenna's bridge is the winner! It can hold more weight than me and I weigh almost 140 pounds!" At this point a student chimed in, "Really? I would have guessed more..." SORE PRIDE
