The Gravity Discovery Centre offers a large number of hands on science and physics discoveries for kids, including a replication of Galileo Galilei's leaning tower experiment up a 45m steel structure.
There is a 1km Solar System Walk made accurately to scale (each footstep is approx. 6 million km) with a family quiz to take along with you and planets, moons and more to discover.
Interactive experiment features include magnetic levitation, ion drive lifter, corkscrew laser, visible sounds and vibration training. Principles accessible for around 5 and up but pre schoolers will still enjoy taking part.
