- 1/2 cup of baking soda
- 1/4 cup of vinegar
- 1 tsp. sugar
- 1/4 cup cornstarch
- 1-2 drop of food colouring
Mix the baking soda and vinegar in a large bowl. This will cause a fizzing reaction. Mix it until fully dissolved & then add the sugar until dissolved as well.
Add the cornstarch and stir well. The mixture may keep clumping, but it does soften when you stop mixing and will pour smoothly.
Pour the mixture into an ice cube tray, giving each compartment an equal amount of mixture. We filled them about halfway.
Mix in a drop or two of food coloring or however much it takes to get your desired color. Stir using a knife.
A little goes a long way. We only needed a drop in each compartment.
After we mixed all the colors. We ended up with a total of 10 colors. We set them out to dry overnight. In the morning our colors had hardened. It may take longer depending on the room temperature & humidity. Do not store anywhere too humid.
Have a go with your new paints the next day. They should work beautifully & the colors are lovely.
