The seventh grade students tested their toothpick bridges today. A bucket was hooked to each bridge from below, and water was slowly added to increase the weight supported. The students designed and built their bridges from toothpicks, string, and glue that had assigned costs. The goal of the project was to support the most weight with the lowest construction cost. This year, the winning bridge had a construction cost of "$9200.00" per pound. It supported 5 pounds of water!
