Necks On Beer and Soda Bottles

Nearly everyone on the planet knows the familiar shape of a beer bottle. It’s no great mystery why the bottle was invented, but have you ever stopped to wonder about the design of the beer bottle. Specifically, why is the “neck” so long and shaped the way it is?
Well, as it turns out the bottleneck shape is intentionally designed to encourage a person to hold their beer at the top of the bottle, where their body heat won’t warm up the rest of their beer before they can finish it!
