It’s all about hands-on fun at the Ontario Science Centre. At KidSpark, those 8-years-old and younger can float boats, build skeletons, balance balloons on air currents and lots more. A gated, cushioned area for toddlers has big trucks, fish tanks and books. The Weston Family Innovation Centre challenges teens with a variety of possibilities. Teens can craft aerodynamic shoes, take apart computer circuit boards, compose sound tracks and see what they look like in a photo made from oil and air bubbles.
