So this middle-of-nowhere town in Washington got the stupid idea to build a 60+ foot tall Lava Lite in the center of town, to "promote tourism." Now generally, I'd say that's exactly the kind of stupid idea the world needs more of. But I'm unconvinced that it's going to actually look like a lava lite: why would you expect dynamics of the fluid to scale with the size of the bottle? They'll have to find some new mixture for the goop that has a melting point and density that is tuned to the gigantic bottle, and it's not obvious that that's even possible.
Plus, the thing's going to take a hellacious amount of juice: it will take no small amount of heat to keep hundreds of tons of wax in liquid form. Would one even be able to stand anywhere near the glass? Doubtful...
(I've given a lot of thought to lava.)
