Why? Because it might be the invention of this century!
Pocket Gadget has created a list of accidental inventions that turned out to be some of the most useful things ever created by mankind. I enjoyed reading Serendipity: 10 accidental inventions, that I highly recommend you to check it out as well.
My favourite would be the humble superglue. In addition to using it to mend countless broken porcelain ornaments, I’ve even used it once to close a somewhat nasty open wound… and it worked!
Mind you, I’m not saying that you should just superglue your wounds shut… the only reason I did it was because I was on a camping trip in the middle of nowhere. Yes, old-school camping, and not some enjoyable gathering in Pigeon Forge cabins!
