These soapstone ice cubes sure give new meaning to "on the rocks." (Sorry, we couldn't resist.) The blocks can be frozen to keep your drink cold without meltoff dilution. We were a little skeptical about how useful they would actually be, but then we saw that they can be heated as well to keep your drink hot. That's rather intriguing. Has anyone ever tried these soapstone "ice" cubes, and if so, what did you think? ($16.95 at Greenfeet)
