~ do you know how to make this home made craft?

~ I was at the craft store, and there was this box of what looked like styrofoam peanuts,,,,you can make designs,,,little scuptures ect,,,,,great for little kids. It said its made from corn starch. I think the name was something like munoodles. And clean up easy, just wash them down the sink when your done,,,,, I would like to know if anyone has home made recipie for these,,,you know like when people used to make home made play dough.
