Who hasn't been mesmerized by one of those goofy crazy-armed dancing tubes found around town? Build your own working mini version of the iconic figure (and more) with the Thames and Kosmos Incredible Inflatable Aero Dancer. Discover the inner workings of this nutty character as you learn about pressure, airflow and aerodynamics. With this kit, you can also make a ball float on a stream of air, practice your aim in a game of air basketball, and launch balls with the air cannon. Kids will learn about physics while also having a fun time building these neat air-powered contraptions.
