Should someone tell you "Last night, I saw a great white shark swimming through my living room," don't assume that they're crazy. It could be that what they saw was an Air Swimmer. The remote-control toys (which are available as a shark or a clown fish) are able to swim through the air, turning, diving and climbing on command. Now all we need is an RC model penguin, that flies underwater.
The Air Swimmers' bodies are mylar balloons that the user fills with helium, much like the RC blimps and flying saucers already on the market. While those models move using propellers, however, the Air Swimmers actually move through the air by swishing their tails from side to side. The user controls the tail movements using an infrared remote control unit - alternating left-right swishes move the fish straight forward, while more swishes on one side or the other turn them left or right.
When first setting up the Air Swimmers, users insert some included putty into the control pod, located on the underside of each fish. They adjust the amount of putty until its weight is such that the model is neutrally buoyant, neither falling to the floor nor rising to the ceiling. When the fish is flying, a button on the remote causes the pod to slide forward or rearward on an attached plastic track. Moving it forward causes the model to dive, while moving it back causes the model to climb.
Air Swimmers are available online, at a price of $US39.99 each. They require one AAA battery for the pod, and three for the IR controller.
Here's a look at them in action:
Helium resources are pretty much finite. Every time some grotty little child releases a helium balloon, we lose more of it to Space. Please stop making stuff like this!
Then they could make the next part of JAWS movie series
@chinna Helium is finite... like u mentioned, its refined from natural gas which just has 7% of it, and unlike most gas, it is unrecoverable once you release it in the air...
\"The Future
In 1996, the United States government proposed that the government-funded storage program for helium be halted. This has many scientists worried. They point out that helium is essentially a waste product of natural gas processing, and without a government storage facility, most of the helium will simply be vented into the atmosphere, where it will escape into space and be lost forever. Some scientists predict that if this happens, the known reserves of helium on Earth may be depleted by the year 2015.
Through 2004-2006, both helium consumption and the costs of producing helium increased. In the 2002 to 2007 period helium prices doubled, and during 2008 alone the major suppliers raised prices about 50%.\" Various internet sources, incl Wikipedia.
The reason the helium storage was even started was to have a secure source pre WW2 for airships instead of using hydrogen. And you might find that the helium used to fill one modern commercial blimp adds up to more than the helium that will be used for all of these fish being sold. And they inflate and deflate airship quite regularly for storage and transportation. You guys are complaining about burning a match when there are multiple volcanoes out there doing a wee bit more.
