How do tightrope walkers stroll so easily on a thin cable suspended in mid-air? What's the trick contortionists use to fold themselves into small tight spaces? How does one swallow a sword and not pierce any vital organs? Turns out, these popular circus acts involve a lot of science than we might imagine.
Gleam insights into the whys and hows of mind-boggling and gravity defying acts at Circus! Science Under the Big Top, a travelling exhibition that's originally from the Ontario Science Centre. There are over 20 interactive exhibits to explore, including a trazepe station where you can strap on a harness and do cartwheels in the air, and a tightrope suspended 3m above ground where you can test your balance.
