It will be part of Red Bull's Flugtag Chicago, which takes place at North Avenue Beach.
Friday, the team put their final touches on their bus creation, which was inspired by the popular children's book and TV series.
This homemade, human-powered flying machine will compete against a few dozen others to see how long it will stay airborne before plunging into Lake Michigan.
They will be judged on flight distance, creativity and showmanship.
