Maybe you didn’t know but WD-40 stands for Water Displacement, 40th attempt. Name was coined by the chemist, Norm Larsen, while he was attempting to concoct a formula to prevent corrosion by displacing water. Wikipedia: “In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place.” Norm’s persistence paid off when he perfected the formula on his 40th try.
Never knew that… thats pretty interesting.
wow nice fact. i’ve been using WD-40 all my life with out knowing anything about it. thx for the info!!!
