PERFECT Slime Recipe

Let’s make slime the science way! In this video, we’ll explore how to create stretchy, squishy slime using three simple ingredients—glue, baking soda, and contact lens solution—and uncover the science that makes it all come together. This classic slime recipe is safe, easy to follow, and perfect for exploring the amazing world of polymers. We’ll start by squeezing white school glue into a bowl—this glue is made of polyvinyl acetate, a type of polymer. Polymers are long chains of molecules that slide past each other, which is why glue feels sticky and smooth. Next, we’ll add a small amount of baking soda (sodium bicarbonate)**. This helps balance the acidity in the mixture and gives the slime structure, preparing it for the next big reaction. Now comes the magic ingredient—contact lens solution! The secret is that most contact lens solutions contain **boric acid or sodium borate**, which reacts with the glue’s polymer chains. When the borate ions from the solution meet the glue molecules, they start to link the polymer chains together. This process is called cross-linking, and it turns your liquid glue into a stretchy, rubbery solid we call slime. The more you knead and mix your slime, the more evenly those cross-links form, giving you the perfect stretchy texture. If your slime feels too sticky, add just a few more drops of contact lens solution and keep mixing. Too stiff? Add a bit more glue to loosen it up! You’ll end up with a smooth, stretchy, and satisfying slime that’s fun to play with—and you’ll understand the chemistry behind it too. Remember, slime isn’t just a craft—it’s *science you can touch*! So grab your ingredients, follow along, and let’s mix up some fun. ✨ *Materials You’ll Need:* 1 cup white school glue 1/2 teaspoon baking soda 1–2 tablespoons contact lens solution (must contain boric acid) Bowl and mixing spoon 🧪 *Scientific Concept:* Cross-linking polymers through a chemical reaction between polyvinyl acetate and borate ions. 💡 *Science is wherever you are!* Watch, learn, and experiment as we make science squishy and fun!
