Street experiments, big-time science busking, mobile contraptions and a cacophony of artists and performers await. Roll up your pant legs and try the cornstarch walk or meet the maker of an electrical brain. Bring your co-workers or family to this daily open-air happy hour and see a side of the greatest adventure story on earth – yes, science and engineering! There are more than 16 activations to explore along Stephen Avenue Walk, between 1 Street SE and 3 Street SW, like a father-son creation called the Borealis, or the original Calgary MakerBus, a mind-bending Camera Obscura or a student-made Brainstorm. Test your voice to see if you sound “authoritative.” Channel your Jackson Pollack with milk paint. Hop into the Lumbering Contraption, a giant human-sized hamster wheel. There’s more to do than makes this page.
