This science discovery museum has four floors packed over 500 discovery points and interactive exhibits, from wind tunnels to giant marble runs to optical illusions. Lots to learn and experience for all ages with interesting hands-on experiments. They also offer biology, chemistry and physics workshops for both children and adults.

When my kids were in primary school, we always had a season pass, which pays for itself after a couple visits. We usually went once every school break and took the grandparents when they visited. It's a great place to spend a cold rainy day. Also excellent for birthday celebrations.
