This ChemKeg Dominator was created by a former cryogenics technician, and it can keep 4.3 liters of beer ice cold for as long as it takes you to drink it (about half a football game). It’s able to achieve this by using a high quality Pope Scientific bench top dewar flask which is a vacuum thermos commonly used to hold liquid nitrogen.

Here’s the designer talking about it:

I’ve made this stein using a Pope Scientific bench top dewar flask because the former croygenics technician in me won’t let me use an inferior quality dewar. I’ve found Pope dewars still holding good vacuum after 30 years. This is, for all intents and purposes, the very best thermos you’re ever going to find. It is quite common to fill these with liquid nitrogen, let it sit on the lab bench, and when you come back three days later there will still be liquid nitrogen in it.

Now imagine what it can do for beer.

Your last sip of beer will be as cold as your first. A margarita of this size is best shared with eight of your closest friends, but it will be frosty all the way down.

It will keep hot things hot just as well as it keeps cold things cold. That’s an awful lot of hot coffee. Sleeping is for the weak.

The ChemKeg Dominator costs $375 and you can bet I’ll be getting a few of these before the start of football season.
