Some of these are really great. Personally I like the Baby Cage.
Hookay. So, you think that this M3 sub-machine gun—with a shoot-first-and-ask-later curved barrel—is a really stupid, really dumb invention, right? I don't blame you. But, trust me, you don't know what really stupid, really dumb inventions are. Yet.
I just saw a selection of 30 dumb inventions in Life, and I couldn't resist picking my favorite ten. These things are so damn stupid they became obsolete before even becoming real products. It was hard to choose. After all, how could I leave out scientology nutcase L. Ron Hubbard and his Hubbard Electrometer, which in 1968 made him reach the conclusion that tomatoes 'scream when sliced'? See? Really hard.
Then I thought that these all looked weirdly familiar. I searched in Gizmodo, and instantly found their modern counterparts. Some of them make sense now, with current technology. Others, as you will see in the gallery, seem equally goofy. All of them, however, we can live without. Enjoy:
Clearly, humans are the only animals that trip twice over the same stone.
