yeah this is pretty much the same foam as those crayola packs. you can add in the Styrofoam if you want to, it makes it look cooler and is better feeling sensory wise. But its optional. I used to make this stuff when I babysat. Kids love this stuff!
OK, Thanks. It looks pretty cool. So does it dry and then can be painted? Or does it stay soft so they can reuse it again. Thanks for answering my questions too my favorite Sellers are the ones who do that :)
