It's a stacking toy with a spin-literally! Drop the vibrant discs onto the threaded corkscrew pole and go ooooh as they spin fast and smooth to settle onto the reversible base. Choosing how to set the base is half the fun for your toddler. Pick either the wobble base or turn it over for a solid seat. Each disc is dual-colored, and from largest to smallest, they form a dynamic rainbow utilizing fun shades like magenta, lime, and teal, and your more traditional shades of lemon, red, and sky blue. The star-like discs alternate between daisy style and star-burst shapes, too. Want to make a rainbow? Want to keep all the round-edged shapes separate? You can! Even the smallest disc can spin all the way to the base. Awww, all the discs are in order; what now? Taking the SpinAgain apart so you can start spinning again might just be the best part! Lift up on the easy-to-release central pole and all the discs spin off the bottom! Made of coated plastic that's pleasant to touch, the discs are solid and BPA free. This visually stimulating toy will keep your little ones enthralled as they practice their hand-eye coordination and baby engineering skills! There's stacking, there's twirling, and then there's SpinAgain!
