Duluth, MN (NNCNOW.com)--- Many Northland high school students spent most of the day Wednesday at UMD showing off their engineering skills.
It was part of the American Society of Civil Engineer's 21st Annual Toothpick Bridge Competition.
More than 200 students constructed bridges made of toothpicks and glue.
Bridges were judged on a variety of categories from most aesthetically pleasing to bridges with best load to weight ratio.
To test the bridges strength students applied increasing amounts of sand until the bridges broke.
"students get pretty intense about how much their bridge holds . The interesting thing is that if you watch a bridge break, every student jumps right up off the ground. It's always a shock when their bridge breaks," said John Hinzmann, Program Chair.
The bridge with the most strength held 76 point 8 kilograms of sand.
