There’s a neon-bordered booth for something called a RAINBOW-VAC, a vacuum cleaner whose angle is that it uses water in its canister instead of a bag, and the canister is clear Lucite, so you get a graphic look at just how much dirt it’s getting out of a carpet sample. People in polyester slacks and/or orthopedic shoes are clustered three-deep around this booth, greatly moved, but all I can think of is that the thing looks like the world’s biggest heavy-use bong, right down to the water’s color.
