Gooey Slime

Gooey Slime is a fun science experiment for kids where they make their own polymer at home. Why are polymers important to us? There are polymers everywhere around us. From plastic bottles, erasers, rubber shoes to glue; these items are examples of polymers that are around us.  Polymers are made completely from a large number of similar units bonded together in form of long chain (‘poly’ meaning many and ‘mer’ means units). This special arrangement makes polymers stretchy or rubbery. This experiment will allow kids to know about this concept in the most fun and innovative way!

What to Do ?

  1. Pour 100 mL water in the transparent bowl
  2. Heat it on medium heat in the induction cook top/stove.
  3. A)Add 6 gms of PVA with the measuring spoon
  4. b) And mix it with the stirrer
  5. Let the mixture boil for 10 min
  6. Switch off the induction cook top
  7. Once the solution is luke warm ,add a bit of food colour + glitter into it.
  8. Mix the solution.
  9. Pour 100 mL of water in the other transparent bowl
  10. Add 4 gms of borax in it and mix it.
  11. Your PVA and borax solution are ready!
  12. Fill 10 mL of PVA solution in the measuring cylinder using the pipette.
  13. A)Fill 1 mL of borax in the pipette.
  14. B) Pour this PVA solution in the measuring bowl and pipette out the borax solution.
  15. Mix the mixture gradually!
  16. 14 .Keep mixing until the solution becomes slimy and comes out of the bowl easily.

Working Principle of Gooey’s Slime :

In this experiment,  Poly Vinyl Alcohol (PVA) gets activated  by  Borax  which acts as a cross linking agent and  is responsible for holding the PVA molecules together to form slime .This mixture of  PVA and Borax results in the formation of a polymer which we call it – Gooey Slime! As the name suggests, Gooey Slime is very gooey and sticky and stretchy! Polymers act like solid as well as liquid. If the chains can slide past each other easily, then the substance acts like as liquid, as liquids generally flow. If the chains are joined together then the substance behaves like a rubbery solid
