Having lived in Edinburgh for 5 years, this was one of the few tourist attractions I'd never visited. I went along when Google invited me to an event there, and was blown away. The place is wonderful, with something to look at and try and work out in every corner, nook and cranny. I had an excellent time exploring the mirror maze, walking through the vortex and playing with microscopes. It's the sort of place that you could go time and time again and always find something new. I'll definitely be back.
