This paint is so simple to put together, all you need is cornstarch, water and food coloring or liquid water color (both work, sometimes at the school we have more color options when using the watercolors, but at home I use the food coloring and it works great!).
I do a one to one ratio so if I throw in a cup of cornstarch, I put about a cup of water. There is really no science to this, you just want it to be kind of a milky liquid. After it was all mixed, I poured it into a variety of bowls. Old plastic ones are best.
Lastly, I added colors to each bowl. One thing I should mention is that while both are non toxic, the food coloring mixtures stained hands much more than the water color mixtures. All of it did com out for Avery in the bath that night but I thought it was worth mentioning.
Then you pass out some brushes, older ones if you have them, and let them go to town!
The kids can of course paint the concrete or driveway, but Avery and her friends also had a blast painting a textured wall nearby as well. I love how bright the colors were and how much fun they all had!
The pictures were great and it was such a fun change up from ordinary paint and brush on paper!
