Use the sandpaper to smooth it out. When the edges are all smoothed down, you have a nice smooth Sphere! now make it into a Globe, or a Death Star, or a big non-bouncy beach ball, a rolling stone of death (indiana jones style), maybe an eyeball, someone please make a giant eyeball. Just make sure the paints you use are okay for .
