The Ontario Science Centre is launching a Spring exhibit that will shake the ground under your feet. Nature Unleashed explores natural disasters — the kind that happen every day — from earthquakes such as the one in Haiti, to the floods in Australia. The exhibit runs from February 11, 2010 (that’s tomorrow) to May 1, 2011. Visitors will get to build their own volcano, experience what it feels like to be inside a tornado, measure the magnitude of earthquakes by stomping, and trigger underwater earthquakes to create a tsunami.
