Great fun for kids parties, Halloween or just as a rainy day project
The most difficult part of making slime is sourcing the right combination of ingredients (if you have contact lenses solution, shaving foam and PVA glue all at hand in your cupboards you’re onto a winner!). This is probably the most cost effective recipe (I’d love to know how you can make it cheaper) for making in bulk, say, for a kids party.
So here’s my easy slime making recipe: this is a basic recipe that works really well – feel free to experiment with your own colours and embellishments such as glitter or add polystyrene balls for a different texture.
For the slime ingredients you’ll need:
• 2 tablespoons of craft PVA Glue
• 1 teaspoon of Contact lenses solution (with Boric acid) – Optrex works well.
• Shaving foam – remember must be foam not gel!
• 1 teaspoon of bicarbonate of soda
The PVA glue should be bog standard craft PVA glue (don’t use building or woodworking PVA).
Now Make the Slime
Pour the PVA glue into a plastic bowl, add the contact lenses solution and mix together (add food colouring at this time if required).
Only add a little of the shaving foam at a time (HINT Wilkos sells a large 5 litre bottle, it’s in the DIY section).
Add the shaving foam a little bit at a time and keep stirring the gloop.
Finally, mix the bicarbonate of soda with a little water (about a tablespoon) and add it to the mix a little at a time until the mix is no longer sticky.
It is the contact lense solution that makes your slime firm and it is the bicarb what takes away the stickiness.
If you find your little munchkins have added in too much shaving foam (who can help it, when that fluffy stuff that squirts out of a can is so much fun!), just add a little more of the PVA and contact lense solution, conversely, if the slime is too sticky, then just add some more of the bicarb.
