Practical details
Why it's worth checking out
Questacon Science Garden is an outdoor exhibition in Manuka, Canberra, where visitors can explore science through exhibits connected to sun, wind, water and rock. It is listed for everyone, making it a straightforward option for families, groups and anyone who enjoys interactive experiences outside a gallery setting.
The garden includes Flickering Leaves, where silver discs move in the wind to demonstrate patterns found in nature. At the Rock Xylophone, Small Lithophone and Sound Pillar, visitors can explore how different rocks and materials create sound. The Granite Ball focuses on water pressure, showing how it can support a ball weighing 633 kilograms.
For visitors who enjoy puzzles, NKRYPT offers a more demanding challenge: eight encrypted messages to decipher. Questacon says only about one fifth of its codes have ever been solved, and some decoded messages still contain mysteries. With its open-air setting, hands-on exhibits and mix of natural science and codebreaking, the Science Garden suits curious visitors who want to explore at their own pace. The site currently lists it as open and located outside Questacon.
