We know enough about conditions that cause rain to be able to simulate it in a room. Why not use the principles of vapor and pressure to create a similar effect for snow globes. And then why not add to the mix reducing temperature to simulate snow. It would be neat to flood houses.-- nomadic_wonderer, Nov 28 2006 Or spray snow on ski slopes. Oh we do that already.-- Chefboyrbored, Nov 28 2006 [21 Quest] Conceivably the globe could simulate the melting, evaporation and condensation cycle.-- nomadic_wonderer, Nov 28 2006 random, halfbakery
