AirLoonz are large-scale, air only balloons that have two inflation points: one for the top peice & one for the base. AirLoonz can be filled with air using an air inflator or hand pump. Includes an easy to place elastic strap for assembly. AirLoonz require additional weight for stabilization. A common household item such as a full, unopened soup can or soda can may be placed in the balloon base between the inflated chambers. The balloon and base can be used separately. AirLoonz will not float with helium.
