With the approval of the city council, Soap Lake, Washington is planning to build a giant lava lamp in the center of town in order to draw tourists. The lava lamp, proponents argue, stands for Soap Lake's unique geologic history. Also, it would be totally cool.

I like the idea, even if the planning is taking a long time. I'd never heard of Soap Lake before, and now I want to take a daytrip there and see what's up.
