Come watch the world's greatest solvers of the Rubik's Cube compete for the fastest times under improbable circumstances. New World Records have been set at the last four Exploratorium-hosted Rubik’s Cube events. Will it happen again? This event is included in the price of admission to the Exploratorium. Entry into the competition is open to anyone, although only the very fastest solvers will advance to the final round. Registration is from 10-11am. Competition begins at 11am.
