These Lab Flask Mugs Put Your Dweeby Thermos To ShameS

Steins of Science, created by a UC Berkeley physicist, are drinking mugs made from heavy-duty lab flasks. Just think how chilly beer stays when it's wrapped in a vacuum "100,000 times more powerful than that of your average thermos."

The Steins, which come in a variety of sizes, surround your liquids with two layers of silvered glass, apparently putting less scientific thermoses to shame in terms of keeping your hot liquids hot and your cool liquids cool. Serious science-minded beer drinkers owe it to themselves to investigate. It's research!

Here's the mad scientist's description of the $340 "665ml FMJ Playa Grade Stein of Science":

I've made this stein using a bench top liquid nitrogen dewar flask. 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. Beer is meant to be consumed at the temperature it comes off the tap and very few bars will let you behind to position yourself under the keg. This is the next best thing.

Your last sip of beer will be as cold as your first. Alternatively, you can enjoy a margarita on a warm summer day without it getting all melty. It will keep hot things hot just as well as it keeps cold things cold. That's an a fair bit of hot coffee.

Oh, and in case you were wondering if they were microwave safe, they're not. "With as much metal as this stein has, it will destroy your microwave." Oh! K! The steins run from $200 to $500, and you can pick one up for the beer-drinking scientist in your life over at Thrillist. [Steins of Science via Thrillist]
