It's a particular skill that takes quite a bit of concentration- and a whole lot of toothpicks.
That's what dozens of high school students are doing in Duluth on Thursday as part of the 2018 Toothpick Bridge Contest.
The contest itself took place at UMD's Ward Wells Field House, with several high school teams participating.
"I think that my favorite part about it was just being able to come here and see everyone else's bridges, and what they did, and different designs they had," said Cromwell-Wright sophomore Cheyenne Smith.
This year marked 25 years for the annual competition.
Vera Scott of Hermantown had the strongest bridge.
