24. The History of WD40
You’ve probably heard of WD40 before. You may have even used it. This spray can do a lot of different things and acts as a lubricant, moisture displacer, rust preventative, and so much more. Basically, this magical item can do everything from help remove paint from a floor to remove rust from saws.
A lot of people swear by this stuff for different reasons, so it’s pretty funny (and very interesting) to learn that the first 39 trials of the item were complete failures. The only reason WD40 has the name WD40 is that every other number failed. But there is a life lesson in here! Never give up trying, even after 39 failed attempts!
