LINCOLN, Neb. (AP) — University of Nebraska-Lincoln students are building cars for an upcoming competition — and then they have to eat them.

The Incredible, Edible Vehicle Competition will take place Tuesday in the Great Plains Room of the Nebraska East Union from 2 p.m. to 4 p.m.

Students are required to make cars out of food, and nothing else. Teams will roll their cars down a sloped track to see which one travels farthest while staying in one piece. They also have to make a poster explaining how they created the car.

The students are from an introductory class on biological systems and agricultural engineering.

The food used includes vegetables, sausage, cheese and candy. This year’s competition limits each vehicle to 1,300 calories.
