Fodor's Expert Review Questacon—The National Science and Technology Centre
This interactive science facility is the city's most entertaining museum, especially for kids. About 200 hands-on exhibits in seven galleries use high-tech computer gadgetry and everything from pendulums to feathers to illustrate principles of mathematics, physics, and human perception. There are daily stage shows (about such things as rockets and natural disasters), puppet shows, and talks. Staff members explain the scientific principles behind the exhibits. The free-fall slide (with a drop of 20 feet) and the 360-degree swing are huge hits with all ages. It's pricey, but kids (and their parents) love it.
