A solution of polyvinyl alcohol (PVA) can be made into a slime by adding borax solution, which creates cross-links between polymer chains. This experiment is easy to set up, providing the chemicals are available, and should take no more than about 30 minutes. It can be done by students in groups of two or three.
How to Make Super Slime. 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. Add 2 teaspoons of the Sodium Tetraborate (Borax) Solution into the PVA solution and stir slowly.
Making PVA Solution. Add 30 g or 1 ounce of PVA powder to 500 ml or 16 fluid ounces of cold water in a bowl or double-boiler. Leave it for 1 hour to for the water to absorb the PVA. Put the bowl with this mixture into a saucepan with water or used the double-boiler.
Step 1: Dissolve the Polyvinylalcohol in water and make a 4% solution. In a steel or aluminum saucepan add 1250 ml water (5 of the blue measuring cup). Add the entire 50 grams polyvinylalcohol to the saucepann.
If desired, one or two drops of food color can be added to the polyvinyl alcohol solution. Stir the mixture. Measure 5 mL of 4% borax solution. Pour the borax solution into the cup of polyvinyl alcohol and stir well. Describe what happens. Remove the material from the cup and knead it in your hand. The material will become firm and lose some of
This slime recipe requires a 4% solution of polyvinyl alcohol (PVA) and sodium tetraborate (that’s Borax). Slime made with PVA is often referred to as commercial or “professional” slime. This is the type that is generally found in toy stores.
There are two methods for preparing a 4% aqueous solution of polyvinyl alcohol, the conventional heating method and the microwave heating method. The microwave method is much easier and less time consuming.
