Chill Maintaining Glasses

Chill Maintaining Glasses
via Hammacher Schlemmer

These are the pilsner chill maintaining glasses that keep beer chilled between 32° F and 36° F for 30 minutes. The double-walled glasses have a viscous cooling liquid between both layers that freezes after one hour in a freezer, enabling the glasses to chill a room-temperature libation to 36° F in just 2 1/2 minutes.
