Incredible Inflatable Aero Dan

$19.99
Bring physics to life with this waving, wacky tube-dancer! Assemble the tube and fan, learning about airflow, air pressure, gears, and circuits in the process. And then? Watch the tube bust a move! The 8-page manual gives step-by-step instructions, along with scientific explanations and even ideas for further fun: launch balls or make them float in air; or even play a game of air basketball! Requires 1 9V battery, not included.

From Thames & Kosmos, for ages 8 yrs-teen.
