I read an article recently about

(yes, that's right, chalk).
The skibums (esp. the youngest two) love sidewalk chalk specifically.
Did you know....
-that "school chalk" is made of a kajillion tiny little microscopic marine organisms? (So draw a fish on a chalkboard)
-that sidewalk chalk is made from evaporating a mineral (gypsum) from seawater?
-and (my favorite) that gypsum is also used as the white filling in drywall.....and as a dough conditioner in Twinkies!!! (yech!!)

I thought Twinkies had a slightly chalky taste. Butterscotch Krimpets Rule!
