How To Make Slime With Glue And Borax

Did you know you can make your own slime or “goop” for a fun learning and play activity, Non-Newtonian liquids are fascinating for all ages and provide a great learning opportunity about chemistry. Find four popular slime recipes below. 1. In one bowl mix 1 oz. glue (about ¼ of the glue bottle) and ¼ cup water. If you want colored slime, add food coloring to the glue and water mixture. Lift some of the solution out of the container with the stir stick and note what happens. 2. Add ¼ cup of Sodium Tetraborate (Borax) Solution to the glue and water mixture and stir slowly.

3. The slime will begin to form immediately. 4. Stir as much as you can, then dig in and knead it with your hands until it gets less sticky. This is a messy experience but is necessary because it allows the two compounds to bond completely. Don't worry about any leftover water in the bowl; just pour it out. 5. When not in use, store the slime in a plastic bag in the fridge to keep it from growing mold. The second type of slime is the same clear gooey kind that you see in the movies. This is the real gooey deal!

1. Pour ½ cup of the polyvinyl alcohol (PVA) solution into a beaker, jar, or bowl. If you want colored slime, add food coloring to the PVA solution and stir with a stir stick. 2. Add 2 teaspoons of the Sodium Tetraborate (Borax) Solution into the PVA solution and stir slowly. 3. Try lifting some of the solution with the stir stick and note what happens. Once the slime has formed, you can play with it. Just don’t eat it! 4. Your slime will last longer if you seal it in a plastic bag and keep it in the fridge, otherwise it will dry out or mold. Polyvinyl alcohol (PVA) is a liquid polymer and is therefore formed from long chains of connected molecules. The sodium tetraborate forms hydrogen bonds with oxygen present in the PVA chains.

Hydrogen bonds occur when the positive charge of the hydrogen atoms attracts the negative charge of the oxygen atoms within the compound. The hydrogen bonds link the individual PVA strands to each other, creating a “blob” of slime. Since hydrogen bonds are weak, they will break and reform as you hold the slime or let it ooze onto a flat surface. This slimy substance is made from milk. 1. Add 7 tablespoons of skim milk to a cup and add 1 tablespoon of vinegar to the milk. Gently stir the mixture until solids have formed. 2. Let the solids sink to the bottom of the mixture and then drain off the liquid using a filter (a coffee filter works best). Let the solids drain for a few minutes. 3. Add ¼ teaspoon of baking soda to the solids and knead together to form a slimy mixture from milk.

When you added the vinegar to the milk, it caused the milk's protein, casein, which is also a polymer, to separate from the liquid part of the milk and clump together to form solids. Casein is used in adhesives, paints, and even plastics. The baking soda neutralizes the acid added, which allows the casein to go back to its liquid form. Make a non-Newtonian fluid that resembles quicksand using cornstarch. 1. In the plastic mixing bowl, combine small amounts of water and cornstarch together to form a mixture that looks like heavy whipping cream and has the consistency of honey. The approximate ratio of the cornstarch to water mixture is 2 cups of cornstarch to 1 cup of water. So if you use all of a regular-sized box of cornstarch (about 16 oz.), you will use about 1½ cups of water.
