Good Questions: Chip Bags, Mushrooms & Cutting OnionsJames from Apple Valley asked: Why are potato chip bags so full of air? Frito-Lay, the largest of the chip makers, says the following: "Our chips are packaged by weight depending on bag size. Prior to sealing, we add air to the bags to cushion the chips and help prevent breakage."
Good Question: Reply All: Speedometers, Red Barns & Onion TearsMary from Eagan wants to know: Why do speedometers go so high? Her Honda CRV says 140 mph, but she, like many of us, would never go that fast. According to Larry Dominique, a longtime automotive engineer and current president of ALG, there are two reasons: 1) Consumer research shows that when people are driving on the highway, they like their speedometers to be between 11 and 1, like on a clock. That makes the needle easier to see at highway speeds. 2) Consumers believe that a car that says it can go 140 mph is better than a car that says it can go 120 mph.
