Be warned - it gets VERY full at peak times! They are open until 10pm, so if you have the option, try to go later. Most of the exhibits are "hands on" so you will have more fun if you're not queuing for everything. The mirror maze and vortex tunnel were particularly good - we didn't let a little motion sickness stop us from trying them three times!
