Air Swimmers are helium filled durable nylon balloons shaped like a great white shark, bass or clownfish (aka Nemo). They are controlled with a battery powered infra-red handheld controller that has a 40 foot range to let them “swim” through the air with life-like motion. The fish are 57 inches long and 36 inches tall and are designed to be used indoors. The fish stay inflated for up to two weeks and can be reinflated over and over anyplace where helium balloons are sold. Air Swimmers are made by WMC and are available for $23.94 from Amazon.
