We use liquid PVA (Polyvinyl Alcohol) in our slime recipe. This is a different product to the popular wood glue which is Polyvinyl Acetate.
One very important fact before we begin, Polyvinyl Alcohol is non-toxic.
The first step of making really great slime is to make PVA Solution, a very easy process. Some recipes use PVA powder, the results are usually disappointing. Using PVA solution makes all the difference. It is the difference between OK slime and Great Slime! Everybody loves great slime.
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. Put it on a low heat, the idea is to gently disolve the PVA, not to boil it. d Stir the PVA and water solution until the PVA is completely dissolved and the solution is consistent.
- Strain the PVA Solution through a piece of fabric to remove any remaining small lumps of PVA.
- Put the PVA Solution into the jar with a lid
- The PVA Solution will last for many months and be ready to make fabulous Slime!
