There are so many wonderful ideas in different blogs and websites. I found this funness through searching! And I can't remember for the life of me, who's blog I found it on, but I know SEVERAL different bloggers have done this with their kids. It's called Cloud Dough!!
You mix flour and baby oil. That's it! And it becomes this wonderful, soft, great smelling dough to play in!!! I just LOVE it!!! I made it up for a sensory box for my son and he had a blast playing in it. Store in a container with lid, so you and your children can get several fun uses out of it!! :) It's been days and my son STILL enjoys it :)
