This is the greatest invention never actually invented. I think. Maybe it was. Can't be sure. But I do know I can't find it for sale anywhere.

Originally seen on Gizmodo, it is essentially a steel cylinder filled with cryogen and topped with a rubber cork.

To keep your beer forever cold, you'd lower the coolight (if it existed) into your beer, push the cork onto the neck and drink out of the hole in the cork. A colored LED displays the time and temp. Pure genius.

Now we just need to form a petition to get it into production.
