Slime is all the rage at the moment... Use our recipe to make your very own slime! All you will need is: 


- A disposable plastic cup/bowl/cleaned out yoghurt pot

- A desert spoon

- Glue spreaders / lolly sticks / plastic spoon

- PVA Glue 

- Bicarbonate of soda 

- 5ml eye wash / eye drop (brand you will need will be pyrex or 'Boots' own brand) 

- 1 pipette

- Small shot glass

- Ready mix paint (optional - if you want it to be white, you won't need it!)

- Shaving foam (optional)

- Paper towels 

What you need to do...

  1. Put 1 level dessert spoon of white PVA glue into the bottom of a plastic cup. This can be very messy, so

    children may need help or be given a container with the PVA already in it.

  2. Add a pinch of bicarbonate of soda (sodium bicarbonate) and mix well using a spoon or glue spreader.

  3. For coloured slime, add 1 drop of ready mixed paint and mix well (deep colours work the best).

  4. Optional step – for a smooth, tactile slime, add 1-2 squirts of shaving foam to the mixture and stir well.

  5. Add 12-15 drops of eye wash/eye drops and mix well. Depending on the amount of PVA glue used, children may need to add more drops of eye wash until the slime sticks together. Be careful not to add too much or the slime will not be as elastic. In trials, we found you need no more than 19 drops for 1 ‘enthusiastic’ dessert spoon of PVA.

  6. Mix the slime for 2-3 minutes in the cup.

  7. Take the slime out of the cup and continue mixing and kneading with fingers.

  8. If the slime sticks to fingers too much, add another 1-2 drops of eye wash/eye drops. Also try dusting a little baby talc over the sample and kneading it some more.

  9. The more you knead the slime, the better the texture. Pull it apart, mix it together, roll it into a ball and then put it on the table, tap it, rub it. What happens?

  10. Enjoy investigating the properties of the slime.

  11. Ensure all the children wash their hands properly with warm water and soap after making and

    handling the slime. Wash tables with soap and water, similarly, wash any equipment you plan to reuse.
