gotta love the big ice sphere or cube. some of the contraptions are pretty pricey, but I did see a couple for less than last year. I have 2 of these big gray silicon molds spheres and a set of 4 smaller ones. also a tray that makes big cubes (square). Don't care if they're crystal clear or not.
btw, glass is Spiegelau crystal...these seem to have been d/c'ed, unfortunately.
