We may have celebrated the anniversary of the moon landing this week, but let’s pause to remember what is potentially an even greater example of American ingenuity: WD-40. The stuff is like duct tape: It solves approximately a zillion common household problems. Sadly, the man responsible for popularizing this miracle spray, John S. Barry, has died. His legacy will of course live on, as it did in my quarters last night, when we had to remove sticker goo from a pair of newly purchased toy guns.
