Ever see those gigantic orange round things on the road, not the road cones, but the big cylindrical ones? Ever try takeing the bottom off of one, takeing the flasher on top, and putting a bowl in the top? Ever try takeing that assembly and sticking it in a large round trashcan full of water, with a drain spout at the bottom and a reservoir to store the water? No? Try it. Your lungs will hate you in the morning!
