Liquid starch7/14/2023 ![]() ![]() It does and you can use slime making to explore states of matter and its interactions. Keep stirring until you have a gooey blob of slime. You will see the slime immediately start to form and pull away from the sides of the bowl. Can you change the density? Did you know that slime aligns with the Next Generation Science Standards (NGSS)? STEP 3: Slowly pour in 1/4 cup of liquid starch and stir well. Slime is called 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. How do you make slime? It is the borate ions in the slime activator (sodium borate, borax powder, or boric acid) that mix with the PVA (polyvinyl acetate) glue and forms this cool stretchy substance. 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! We always like to include a bit of homemade slime science around here! Slime is an excellent chemistry demonstration and kids love it too!
