Basic Slime Recipe – Blue Star Glitter

Basic Slime Recipe-Blue Star Glitter

I thought it was well overdue for my daughter and I to get on the slime band wagon! I’ve been meaning to make slime for so long. I’ve finally found some spare time to give the basic slime recipe a go. And I can’t believe how easy it is!

If you’re like me and haven’t tried slime making with your family yet, then you definitely should it’s great fun! Maybe even a little addictive. I’m already wanting to try all the different versions of slime out.

But I should tell you before you start, we didn’t find it as straight forward as all the videos and posts out there make it look. It took us 5 attempts before it actually worked!

Once we sussed it out, it was so easy from there. But here’s what we learnt not to do:

Here are some tips before you start 

1. Our first fatal mistake was buying the wrong glue ( I didn’t even realise this was possible). I just thought white craft glue was pretty much PVA. Turns out it’s not. So make sure you check that the glue you pick up doesn’t have alcohol in it, otherwise it will separate as soon as you add the water! It is best to use PVA or Elmers glue.

2. This is a science, so getting the ratios right really is important. So get out those measuring cups and spoons.

3. It can take a few minutes for the mixture to come together so just keep stirring. Also if your mixture comes together but there seems to be a lot of liquid left behind, simply pull out the combined mixture and knead it on the bench, it will start to come together.

Basic Slime Recipe – Blue Star Glitter

What you need

1/2 C warm water
1/2 C PVA glue
Glitter
Food colouring
1 medium bowl
A mixing spoon

Borax solution

1/2 C of hot water
1 tsp of Borax powder (we bought ours from Bunnings)

What to do
1. Pour half a cup of PVA glue into your bowl

2. Add half a cup of water to your PVA glue and mix well. Make sure it’s completely combined.

3. Once the PVA and water are mixed well, you can add in a little food colouring and glitter if you wish.

3. In a seperate cup make up the borax solution by combining half a cup of hot water with 1 tsp of borax powder, and stir until most of the borax is dissolved.

4. Add the borax solution to the glue and water mixture, and mix really well for a few minutes. The solution will start to come together.

5. Once the solution is combined, take it out of the bowl and knead lightly on a bench. It might seem very wet at first but keep kneading, you’ll be surprised at the result!

Storing

You can store you slime in a ziplock bag or a sealable plastic container. The slime will keep for at least a few weeks, up to a month. Over time the slime can become sticky, or brittle, and often gets bits of dirt and dust in it. And that’s about the time to whip up another batch and see what else you can create!

The science behind slime – It’s all about the ‘polymers’

Ever wondered how slime works. Well check out this amazing explanation by the good people over at ThoughtCo:

The basic explanation of how slime works is that chemicals are mixed together to form ‘polymers’. The polymers act as a net, with molecules sliding against each other.

  1. Two solutions are combined to make classic slime. One is diluted school glue (PVA glue) or polyvinyl alcohol in water. The other solution is borax (Na2B4O7.10H2O) in water.
  2. Borax dissolves in water into sodium ions, Na+, and tetraborate ions.
  3. The tetraborate ions react with water to produce the OH- ion and boric acid: B4O72-(aq) + 7 H2O <—> 4 H3BO3(aq) + 2 OH-(aq)
  4. Boric acid reacts with water to form borate ions: H3BO3(aq) + 2 H2O <— > B(OH)4-(aq) + H3O+(aq)
  5. Hydrogen bonds form between the borate ion and the OH groups of the polyvinyl alcohol molecules from the glue, linking them together to form a new polymer (slime).
