If you have never seen the Illuminations globe enter the lake check this video out.
I'd never really given it much thought before. To get the globe in they raise one of the bridges near the Africa trading post. This surprised be because I've crossed this bridge many times over the years and never realized that this was a drawbridge.
The globe itself is rather impressive. I can't imagine how many hours of engineering went into it. It also looks like it could be a monster to try and fix.
You can see the video here.
