Because the weather is getting colder and you need some ideas to keep the kids busy indoors:
1 cup flour
1/2 cup water
1/2 cup salt
Food coloring. If you want to be super green you can use vegetable dyes or the pricey organic dyes at Whole Foods. I figure he’s not eating (much of) this, so I can go cheap and easy with the conventional stuff.
If you store it in a plastic bag or container, it should last in the fridge for ages. Enjoy!
