TULSA, Oklahoma - Green Country students put their creations to the test this week.

Middle and high school students from Bixby, Jenks, Owasso and Tulsa returned to the Fab Lab to show off their moving sculptures Friday.

It's part of the "Tulsa Tinkering School" program, where students use math and science to take apart electronics and turn them into something new.

The one requirement: it had to move in some way.

Some kids used wind power, others used batteries to power their creations. One thing they all had in common was a lot of creativity.
