Sparking Curiosity, Showcasing Youth’s Creativity

Thingamajig® is a Science Fair & Engineering Expo
Thingamajig® offers more than a dozen hands-on challenges designed to spark curiosity and showcase kids’ S.T.E.A.M. skills while they have fun building or simply designing new inventions. It is in its 29th year nationally, and 9th year at the YMCA of San Francisco. It’s one part science demos and activities and another part engineering competition.

Inspire Youth to Be Amazing and Unstoppable!
Join us! The world needs more innovators and hands-on problem-solvers.
