Dumb Inventions Part 1

Life takes a look at what was originally thought of as a "good idea" but then realisation dawned.  Lots of contenders, so this will be spread over the next few posts- and days!

Curved Barrel Machine Gun, 1953

The 20th century saw many astounding technological innovations. The automobile revolutionized the way people live and work, the internet changed the way people think about information, and the U.S. of A put a man on the moon. But some technological advances that came in the earlier part of the 20th century weren't exactly meant for the history books. Because they were stupid. Take, for example, this M3 sub-machine gun with a curved barrel for shooting around corners. It's the perfect gun for the "shoot first, look where you're shooting later" kind of guy.
