Why Do Clocks Run Clockwise?
The second book of Imponderables, and the first to include mostly mysteries sent in by readers, is by far my bestselling book (Anyone know why? Is it the title? The cover? The questions?).
Some of the more popular questions include: If nothing sticks to Teflon, how do they get Teflon to stick to the pan? Why do hot dogs come ten to the package and buns eight to the package? And how do they keep the raisins in cereal from falling to the bottom of the box?
Clocks also introduced "Frustables." Ten frustrating Imponderables were posed to readers (the first Frustable, and the one mystery that has generated the most mail of any subject in the Imponderables books was: Why do you often see exactly one shoe on the side of the road?)
