Drinking out of a plastic cup is not the same as drinking out of something made of glass; clearly there is a difference. For some, the taste is important, for others the heft of solid glass makes the difference. Being able to see the contents of the drinking vessel is certainly a factor as well. But for all that glass does to enhance the drinking experience, it still could do more.
Hammacher Schlemmer, purveyors of everything from Fescue Flip Flops to Five Person Exploration Submarines has two new sets of double-walled drinking glasses up for sale. The Chill Maintaining Pilsner Glasses ($79.95) are shown above, while the Chill Maintaining Wine Glasses ($59.95) are also available. The beer glasses hold 13 ounces and the wine glasses hold 8 ounces. Both come in a set of four.
In between the double walls is a "viscous cooling liquid" that helps maintain the cold. Pop the glasses into the freezer for about an hour to chill them and the glasses themselves then double as a chiller while containing your libation. Fast drinkers and slow sippers alike can enjoy the benefit as cold beverages stay cold for a longer time. Of course, environmental temperatures come into play for how long the chill will last -- so if you want to maximize the effect, just hop in your sub.
