The History of the Miracle Liquid Known as WD-40

You've heard the advice about taking care of your household stuff: If it moves and it shouldn't, use duct tape. If it doesn't move and it should, use WD-40. That's why every home has both. We've covered the history of duct tape; now it's time to learn how WD-40 came about. Do you know what's in that familiar blue spray can? No, you don't, because the exact formula is a well-guarded secret. Do you know what WD stands for? You might, or you mioght be able to figure it out with some thought, but if not, you'll learn it in this video. I was particularly surprised to learn that WD-40 only goes back as far as the 1950s. I guess I had assumed it was ancient. I already had plenty of respect for the product, but I also learned a few new uses that never occurred to me before, way beyond making things move that should. -via The Awesomer
