Madonna once said: âAny publicity is good publicityâ. Soap Lake, Washington is planning (since 2002) to attract tourists by building a 50 ft tall âgiant lava lampâ in the middle of the town. Just curious, how much energy would it consume? Anyway, it sounds exciting, something that will draw a lot of attention and a lot of visitors. I would love to make a major road trip to see something so huge and exciting.
