1 cup cornflour
1 litre water
1 cup soap flakes (optional)
A few drops of food colouring
A few drops of dettol, eucalypus or tea tree oil (optional)
Put the cornflour into a saucepan.
Add about 2 Tablespoons of water and mix to a smooth paste.
Add the rest of the water, turn on the heat and then stir the mixture until it starts to thicken. (Tip: for a smoother, better result, add soap flakes. This will also stop the kids eating the paint).
Pour into seperate containers and add a different food colouring to each container.
To store - put the lids on containers and keep in the fridge for 2 or 3 days. If you want to keep the paint any longer add up to two drops of dettol, eucalyptus or tea tree oil, but having done that, don't allow the kids to eat the paint.
