How to Make Play Slime for Kids

Play Slime

This is yet another great rainy day activity. Play slime is really easy to make, with the base being 3 simple ingredients that you may already have at home.  The slime itself is very tactile, and can provide hours of entertainment for your little ones.

I have been meaning to make play slime for my two for a while now, and today I had some time to experiment with quantities to get the perfect consistency. The kids had a great time playing with it, so did mummy!  They used their Play Doh cutlery to cut it up and make different shapes. Isla liked to stretch it to see how far it would go and Oliver buried his little dinosaurs in it and pretended they were hatching for eggs!

How to Make Play Slime for Kids

Without going to much into the science of it (mainly because I don’t fully understand it myself!) the slime is made by a reaction between the polyvinyl alcohol (the glue) and boric acid (found in small amounts in contact lens solution).

You Will Need

  • 200g PVA glue
  • 1/2 teaspoon bicarbonate of soda
  • Glitter (optional)
  • Food colouring (optional and your choice)
  • 2 tablespoon contact lens solution
  • Bowl and spoon

How You Do It

  1. Add the bicarbonate of soda to the glue and stir until smooth
  2. Add glitter and a few drops of food colouring. Stir well and add more as necessary
  3. Add 2 tablespoons of contact lens solution and stir very slowly until the mixture initially becomes stringy and will form into a ball.

Watch my short live video demonstration I did for Facebook to see exactly how to make it!


Play slime can be played with immediately or stored in air tight container for later.  It is quite safe for the kids to play with, but like with anything make sure the kids wash their hands afterwards.

My kids had great fun with theirs and it kept them occupied for a good few hours. Stretching it, rolling it out, burying their toys in it! It’s amazing what fun such a simple play slime can be!
