The former Portland Mini Maker Fair transformed into the Oregon Science Festival this year, filling OMSI to the brim with STEAM-smart workshops, tours, lectures, and events that celebrated our region's scientists, engineers, and innovators. The fest will conclude this weekend with a two-day scientific "extravaganza," a fam-friendly event with workshops on electronic music, stop-motion animation, and special effects makeup, plus astrophotography-inspired dance performances, shark, mushroom, and dinosaur presentations, and a science circus. There'll be plenty of brain-teasing to go around. by Lindsay Costello
