EVERGREEN, Colo. -- Students of civil engineering from around the world made their way to Evergreen Lake to compete with the best of the best.
All were in canoes made from cement.
"The have to find a way to make concrete either lighter than water or, with the shape of their canoe, can offset the amount so perhaps they are a bit lighter than water," said Kristina Swallow, president of the American Society of Civil Engineers.
"They also have to innovate to insure that it is a lightweight concrete that can float as well as one can steer."
The student competitors are judged on oral presentation, display, final product and the race itself. Design and weight of the entry's varied.
"We had a canoe about 20 feet long and weighs 125 pounds. I think it's the lightest. The heaviest is 370, close to 400 pounds," said Chris Humphries, head judge of the event.
Monday was a lot more than just fun in the sun for the soon-to-be civil engineers. Prestige comes with winning this race, and prestige can sometimes pave the way to employment.
