![]() We call it a Non-Newtonian fluid because it’s a little bit of both! Experiment with making the slime more or less viscous with varying amounts of foam beads. As the slime forms, the tangled molecule strands are much like the clump of spaghetti! Is slime a liquid or solid? Picture the difference between wet spaghetti and leftover spaghetti the next day. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubbery like slime! Slime is a polymer. You add the borate ions to the mixture, and it then starts to connect these long strands together. These molecules with flow past one another keeping the glue in a liquid state. The glue is a polymer and is made up of long, repeating, and identical strands or molecules. What’s slime science all about? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and forms this cool stretchy substance. We always like to include a bit of homemade slime science around here! Slime is an excellent chemistry demonstration and kids love it too! Mixtures, substances, polymers, cross-linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime! Watch our awesome slime videos and see how easy it is to make the best liquid starch slime! ![]() Oh, and slime is science too, so don’t miss the great information on the science of slime below. Click on the slime recipes below to see if any of these will work! This is a pretty common question from those who live outside of the United States, and we do have some alternatives to share with you. I often get asked, “Can I make my own liquid starch? The answer is no, you cannot because the slime activator (sodium borate) in the starch is crucial to the chemistry behind the slime! Additionally, you can not use spray starch! But what if I don’t have liquid starch available to me? You can also find liquid starch on Amazon, Walmart, Target, and even craft stores. We pick up our liquid starch in the grocery store! Check the laundry detergent aisle and look for the bottles marked starch. Read more about the science of slime below. It is the borate ions in the liquid starch, that mix with the PVA glue to form your stretchy slime. Liquid starch for slime works as a slime activator. Liquid starch is a product that is used to make clothing firmer and easier to iron. Check out the full list of slime activators you can use to make slime! Slime making is chemistry and involves a chemical reaction between your mixed, PVA glue, and a slime activator. Add color, glitter, sequins, and more! What Does Liquid Starch Do To Slime? Liquid starch slime is one of our favorite slime recipes! We make it ALL the time because it is so quick and easy to whip up.
