GlowTube - World's First Glow-In-The-Dark Pool Float Inner Tube
It seems like this should have already been invented before, but the cool new GlowTube is the world's first glow-in-the-dark pool float inner tube. This after dark illuminating pool tube charges itself up during the day in the hot sun and then when nighttime sets in, it begins to eerily glow green. Now when you're all night swimming in the pool, somebody will finally be able to spot you before cannon-balling in. It's not only great for nighttime pool parties, it's also fun at the lake or at the beach, but, hmm, I think sharks like to have a late night snack of glowing green donuts, so I'd stick with the pool.
