Building and testing bridges

WSW: Building BridgesThree boys, Two Bottles of Glue, Popsicle Sticks, and a Plan. Welcome to Wacky Science Wednesdays!

Thus, my idea for Wacky Science was born. While I was putting J down for a nap, the boys watched a Bill Nye the Science Guy video on Inventions. Then we headed outside to begin our project. I didn’t give the boys a lot of direction, I mainly said “build a bridge and use glue and Popsicle sticks”. I had a box that the bridge had to reach across and I told them that they had to build it together. Despite being the most reluctant to start, my nephew J’s idea was the best: use two sticks on either side to attach the remaining line, and soon they had this:
