Make professional-grade slime with the Steve Spangler Science DIY Slime Kit. It’s an easy-to-create science kit for kids that is fun for ages 6 and up. What makes our slime formulation unlike anything else on the market is the addition of stabilizing agents that help to reduce the growth of bacteria while preserving the stretchy, gooey properties of slime that everyone loves – but without the glue! It’s an exciting science experiment that’s fun for all ages! You can encourage kids to learn while they’re having fun with this Steve Spangler Science kit. It includes everything needed to create slime and makes a great introduction to how exciting science can be. Plus, this slime has a UV reactive formula that glows under a black light for even more scientific exploration – which is especially fun around Halloween! This science experiment kit for kids is a great way to introduce the concepts of change in states of matter (from a liquid to a solid), as well as demonstrate the process of cross-linking long chains of molecules and explore the science of polymers. Each slime kit includes 1 gallon of PVA with enhanced stabilizers, a 1 L bottle of cross-linking activator, and a step-by-step activity guide. Available in 6 vibrant colors that won’t stain your hands.
