Coolshot

The CoolShot^TM is a patented crystal shot glass with precision fitting top that enables shots of vodka (or other liquors) to be stored in a freezer for extended periods of time, ready for consumption. Manufactured from the finest German leaded crystal, the CoolShot^TM is the only product available for storage and consumption of vodka at subzero temperatures. For vodkaphiles, it is a necessity to have freezer-cold shots of vodka ready for those moments when nothing else will do. In addition to being drunk very cold, vodka is customarily tossed far back in the mouth and consumed in a single swallow. Russians claim the reason for this is a practical one: if vodka is sipped, one inhales the fumes and the fumes are what cause drunkenness faster than the drink itself.
