![]() ![]() These chains slide past one another fairly easily, that keeps the glue flowing.Ĭhemical bonds are formed when you mix the PVA glue and slime activator together. The glue used in slime comprises long chains of polyvinyl acetate molecules (that’s why we recommend PVA glue). Slime is all about polymers! A polymer is made up of very large chains of molecules. If you pull it quickly, the slime will break off more easily because you break apart the chemical bonds. Pull the slime slowly, and it flows more freely. When shear stress, such as quickly stirring or pulling the slime apart, the slime shears or breaks. Slime is an example of Shear-thickening fluids or fluids in which stress causes an increase in viscosity. ![]() However, it can also be bounced like a ball because of its elasticity. You will notice that slime has no specific shape and will change it to fill whatever container it’s placed in. Our 2 ingredient oobleck is another example of a non-Newtonian fluid! It can be picked up like a solid but also ooze like a liquid. A non-Newtonian fluid is neither liquid nor a solid. Additionally, chemistry is how these materials act under different conditions. It is all about how different materials are put together and made up of atoms and molecules. Slime involves chemistry! Chemistry is all about states of matter, including liquids, solids, and gases. ![]()
