The icy shot glass mold makes for a great college party accessory. Fill up the tray(s) with water, or your favorite juice, and in a couple hours you will have ice shot glasses! Plan several days ahead and you can freeze enough shot glasses for your entire party. Ice shot glasses give you a nicely chilled shot, and with the right juice, make for a pretty good chaser! 
It should also be noted that the icy shot glass mold is a great way to save money in college. A typical shot glass can cost as much as a single mold, and if you have friends like mine, they will inevitably break when someone enthusiastically slams the glass down on the table. With ice shot glasses there is no worry over a broken shot glass, and in fact, they can actually be pretty fun to smash!
Cons
Ice melts. With room temperature liquor you will get only a couple shots before the shot glasses become unusable. We recommend using several molds, or planning far enough in advance, to freeze enough shot glasses for the entire night.
The melting ice shot glasses will make a mess after a few shots, and occasionally break causing you to lose some of your alcohol.
Solution: Prepare lots of ice shot glasses ahead of time, and serve them in a designated spot where you can control spillage.
