Did you know that Popular Mechanics editor Matt Allyn is a certified beer judge? Well, he is, and lately, he's been trying truckloads of beer for an article he's working on called 500 Beers of Summer. If he told us about all of them, it would take the next four episodes, so we kept him to five, all of which are exceptionally tasty. Also on this episode, Roy Berendsohn works too much and throws out his lower back, we learn 26 things you can do with a heat gun, and Kevin Dupzyk gets started in sailing.
