These amazing Silly Squares are as fun to watch grow as they are to play with! Put them in a bowl of water and watch them grow up to 100 times larger! Use the included stacker tray to try to build with your Silly Squares! See how tall a tower you can build before it wiggles down. This kit comes complete with 5 different colors, so you can conduct color blending experiments as you create. Best of all, Wiggly Jiggly Silly Squares are reusable!
