Well after 6 cans of foam I'm still not quite done but Easter Dinner is a couple hours away so the rest is going to have to wait. There seems to be a lot of interest in smoothing Great Stuff out. It dries smooth if that is what you guys mean. If you're referring to the size of the rocks being created you just hold the straw on the can still and you can blow a ball of this stuff as big as a basketball if you want. Personally I like the illusion of lots of smaller rocks piled together. Here's a couple of pictures showing my progress so far.
