Built by scientists old and young, entries will include an electric roadster built at the Columbus Idea Foundry and a display of water's erosive power that uses a steel trash can, bricks and a fountain. Awards will be given in categories such as "Most Creative" and "Most Science-y."

Admission to the all-ages event is $5 or free with a COSI ticket.
