It's a science I didn't know needed to be taught. Luke Combs was videoed backstage during a show recently, and he teaches his guests the proper way to shotgun a beer.

Here's the thing, though. He just doesn't show his technique. This man breaks down the entire science of why he is doing what he's doing during the entire process.

Combs explains the location of the air bubble when the can is on its side and how to position the mouth opening along the can so that you can properly get ventilation while you chug. He even shows off his head turn and when to start drinking.

If this country thing doesn't take off for him, he would make one heck of a teacher!
