Miami - Students from Florida International University in Miami walked on water for a class assignment.To do it, they wore aquatic shoes they designed and created."Second year in a row of bragging rights," said Alex Quinones, who was the first to make it to the other side of a 53m lake on campus in record time - just over a minute. Quinones, who wore oversized boat-like shoes, also won in 2011 and will receive $500.The secret, he said, is in the legs."The shoes is part of it, but if you don't have the legs then you're not going anywhere," he said.StyrofoamStudents had to wear the aquatic shoes and make it across the lake in order to earn an "A'' on the assignment for Architecture Professor Jaime Canaves' Materials and Methods Construction Class.The annual race, titled Walk on Water, is an assignment required to pass Canaves' class."It's traditional in a school of architecture to do boats out of cardboard for a boat race. I thought our students were a little bit more special than that," Canaves said. "We decided to do the walk on water event to take it to the next level."Erika Olson's team designed shoes made out of Styrofoam with a piece of plywood extending from the back, wrapped up "with a lot of duct tape.""We had a trial so I knew it was going to be challenging," she said. "But today it was a lot worse. I had to wait for other people to go and it was a lot of work."Some students tried to keep their balance as the shoes wobbled on the surface of the water. One design came apart during the race.Carolina Rivera chose to be the "walker" for her team because she thought "it would be a cool project. But it's so much harder than it looks." Her team also created a boat shape for shoes, but this design had flaps in the back to serve as a flipper."Some people glided through, but it just took so long with the shoes we had. My legs are killing me."Others gave up after an exhausting push."I had no more muscle left to keep it together," said Matt Wasala, who swam the last portion of the race while holding onto his oversized boat shoes. "I thought the design was going to work a little bit better than it did."A total of 79 students competed in the race this year in 41 teams. Only 10 teams failed to cross the lake. Others who fell got back up and made it to the end. The race is open to all students and anyone in the community. The youngest person to ever participate was a 9-year-old girl who competed in place of her mother, while the oldest was a 67-year-old female student.
