It will keep my kids happily busy and building for hours (like Legos!). But, we only use homemade (the one with oil & cream of tartar).
I hate the smell and the food coloring mess so I often use unsweetened Kool-Aid packages (you know, the little envelopes you have to add sugar to) instead of food coloring.
The bonus is, it smells like whatever flavor Kool-Aid you used. The bad is I've had younger kids try and eat it because it smells good. But, it's just salt, flour, water, oil, and cream of tartar so (unless you have an allergy issue) it won't hurt to eat it, it just tastes terrible.:tongue_smilie:
