Edinburgh and the Camera Obscura

I went to the Camera Obscura today. It is so cool. The Camera Obscura is a place where they have special types of glasses and mirrors. We saw Europe's largest plasma dome and went on the Vortex Tunnel. The Vortex Tunnel is a rideish type of thing that was made in a way so that the wall was spinning but not the metal bridge you are standing on. It was creepy but so cool. We planned on doing it once but was so fun we did it twice. Brock fell over whenever we had been on for half of it.
