Spooky Slimer - What Do I Need?

How Do I Do It?

STEP1 - For this experiment you will need to get some Borax. You can either get this from your local pharmacy or online.

STEP2 - Add a 2 cm covering layer of clear PVA glue to your cup.

STEP3 - Add a splash (about a teaspoon) of water and mix it in to your PVA glue to make it more runny!

STEP4 - Add around 5 table spoons of your borax to around 250 ml of water and stir well. Label it appropriately so no one drinks it.

STEP5 - Add a teaspoon of your borax solution to your PVA at a time and keep mixing.  You will need to add around 3 teaspoons in total.

STEP6 - Add eyes to your Spooky Slimer and make sure to wash your hands thoroughly after experimenting!

Spooky Slimer - How Do I Do It?

What’s Going On?

Not only did you just make slime but you also just did a chemical reaction! 

The ‘P’ in PVA glue stands for ‘Polymer’ and you just did a chemical reaction where the glue stuck to itself which is what turned it into slime!

Technically it’s a cross-polymerisation reaction. Your PVA glue is a polymer and that just really means that it’s made of long chains of stringy molecules. 

By adding your borax you cause a chemical reaction that ‘tangles’ those long polymer chains which is what turns your goo into glue.

WARNING: You can’t drink Borax so don’t mix this in anything you’ll use to drink from. 

Make sure that your wash your hands thoroughly after touching your Slimer.
