Have a ball and watch the wonder as this interactive air stacker/launcher teaches little ones the fun side of physics as they stack the tubes up to 35 inches to form their rocket. Then turn on the fan, controlling its airflow, to make the ball hover up and down or make it float in place. Comes with seven tubes and features fun animals, shapes, and numbers to teach early counting. Way to shoot for the moon! Requires 4 AA batteries, included.
From Hape Intl, for ages 2-5 yrs.
