It's endless ball run fun! Grab the ball from the base and instantly, all the other balls roll down to the next level in unison. Drop the ball you just grabbed into the funnel at the top, watch it roll to the next stop, and then grab the next ball to do it all over again... And again and again and again!
Curiosity develops into hours of cause-and-effect learning and discovery. Easy assembly. Includes ball run tower, 5 balls, assembly instructions. BPA-Free. Ages 12 months +
