The Air Swimmers Flying Shark provides hours of remote control indoor fun in even the smallest of rooms (not recommended for outdoor use). They require only four AAA batteries (one in the body, three in the controller) and have complete up, down, and 360 degree turning control.
Simply fill your Air Swimmers with helium, which is available inexpensively at any party store, florist shop, or grocery store that carries balloons. The body is made from a high quality, durable nylon material that will stay inflated for weeks! The Air Swimmers can be filled with helium again and again. Remote control has never come to life so magically!
