Add in glitter or sparkles to give the slime the royal treatment. Make clear slime by using the basic slime recipe with clear glue. Princess slime adds a touch of sparkle and shine to your sensory play. It is so simple to do too! Take the recipe I listed out above and substitute clear glue for regular white glue. Making clear slime is super easy and super cool for kids. (Feel free to sprinkle in some glitter too.) Then add in googly eyes to make it look more like the aliens from the movies! Clear Glue Slime Use green food coloring as your add-on ingredient. These are things like glitter, or coloring, or even heat changing compounds that make your slime change colors as it gets warm. You can also put in add-ons to make it more fun. You can make the slime as runny or solid as you like by adding more water or glue. (This is your Borax, liquid starch, or contact solution.) That’s really it. Mix glue with some sort of slime activator. Most slime recipes follow a similar formula. Learn all the benefits of sensory play-> The Big Benefits of Sensory Play The Big Benefits of Sensory Play. Slime is also an amazing sensory activity and a great way to enjoy sensory STEM play. All of these will make a traditional slime product. It really comes down to what you have on hand. Borax, liquid starch, contact solution, they all play the same part in the reaction. There is more than one way to bake a cake, right? Same with slime. Why are there different recipes for slime? Well, the simple answer is that there is more than one way to cross-link polymers and make non-Newtonian liquids. Adding in a slime activator connects those chains into cross-linked polymers. What makes the slime come together? Glue has polymers or long chains of repeating molecules. These different behaviors are a result of viscosity, or how quickly a fluid flows. If you just leave it alone it oozes like a liquid. If you are kneading it the slime is firm like a solid. Slime is a non-Newtonian liquid, meaning it changes its behavior based on the forces put on it. If you are looking for the short answer for why slime is slime, here is the summary of what I talked about above. This creates your slime that holds itself together better than a regular liquid. They join up and create a lattice-like structure that is more solid. It can be quite viscous, remember that means it doesn’t flow quickly.Īs you add in additional ingredients, like Borax or contact solution, those polymers start cross-linking. It contains polymers that slip around past each other as glue is a liquid. (Sounds high tech, doesn’t it?) Glue is a common slime ingredient. When you mix the ingredients of slime together you are linking polymers. (Too bad we can’t bend and stretch like slime!) DNA and protein contain polymers as well, so you are currently an example of a polymer in action. Silk and wool are polymers, so you might be wearing some right now. Mono=one, poly=many.) These chains can stretch and move, helping to give slime it’s bendy-ness. Polymers are simply chains of repeating molecules that stay linked together. How does slime stay together as a mass? This is the result of polymers. It isn’t just viscosity that makes slime act like it does. But as soon as you stop applying pressure slime oozes and acts more like a traditional liquid. When you roll it around your hand or squeeze it, slime feels pretty solid, similar to play-doh. So what does viscosity have to do with slime? Well, as a non-Newtonian liquid slime changes how it acts based on the forces applied to it. (Yep, peanut butter is a liquid.) If you try to drop it off a spoon it flows very slowly. If you pour it out of a container it flows pretty quickly. What is viscosity? Viscosity is a property of liquids that describes how fast the liquid flows. (Remember ooblecks? Those are non-Newtonian liquids too! Learn how to make them here!) Non-Newtonian liquids are liquids whose viscosity changes based on the forces applied to it. So what is it? Slime is a non-Newtonian liquid. Slime has characteristics of both solids and liquids.
