See 5th Graders Break Their Bridges!
The 5th graders paired up to construct bridges with up to 1000 toothpicks and glue. Then on Dec. 1, 2017 they tested how much weight their bridges could hold using half-pound bags of sand. See a Photo Gallery and a Video of the Bridges Breaking (and sometimes exploding!), including the winning span that held 17.5 lbs!
