My Grandma used to make this for us kids we loved it. and I made it for my kids. The kids love playing with it and you do not have to worry if they decide to eat a little (Which has happened haha) And you can let the kids pick out what color they want . One time I used a package of Kool-aid and it smelled great and colored it.
Homemade Play dough

Food Color ( optional)
Combine in saucepan and cook over med heat
Stirring constantly until mixture thickens into a thick dough.
Remove from heat immediately, As soon as it can be handled knead
it like you would bread for about 10 minutes.
It will last a long time when stored in an airtight container.
