Stretch, squish, and squeeze five different types of slime and putty in the National Geographic Slime and Putty Science Lab! You’ll make batches of red and blue slime, be amazed by purple liquid slime, and have a blast with the blue metallic putty and bouncing putty in this kit. These are great sensory toys for kids, and an awesome way to introduce kids to the science behind slimes and putties. A detailed learning guide teaches about slime in nature, how putty was discovered, and more. Storage containers are included for each slime and putty in the kit.
