An AirWalker balloon should always be filled with helium, so when the weights are added to the balloons, it appears to be magically walking and wandering around the room– based on air circulation.
These balloons are very big and are often larger than the children the balloons are meant to entertain; they do require more helium than most other balloons.
Below we provide a list of the cubic feet of helium necessary to fill most AirWalkers. The manufacturer has not provided the helium specs for all AirWalkers, but we estimate an average of 5 cubic ft.
