Incredible RC flying clownfish and sharks [video]
"Just When You Thought It Was Safe to Get Out of the Water!"
Air Swimmers are large, helium-filled balloons shaped like clownfish and sharks. Each Air Swimmer measures 57 inches long by 36 inches high and is controllable up to 40 feet away with a supplied hand held radio controller. Four AAA batteries are required: three for the RC controller and one for the balloon controller.
Units are fully controllable; they have the ability to go up, down, and in a 360 degree circle using an integrated tail fin that gives the balloon a life-like swimming motion. The balloons are made out of durable nylon material and can be refilled with helium at your local florist, party store, or grocery store that has helium refill tanks. Refilled balloons last for weeks on a single charge. One caveat is that Air Swimmers cannot be used outside as the units require still air to operate effectively.
With Christmas coming up, these would make excellent gifts for any reef aquarist. They are currently on sale for $39.90 per balloon or $77.28 for the pair.
