"If you put a vitamin in the sand, it makes it new"

Quote of the day. A conversation with my son this morning after handing him his vitamin went something like this...

"Guess what, Mom?"
"What?"
"If you put a vitamin in the sand, (now whispering) it makes it new."
"Wow, I didn't know this. How does it make it new?"
"You take your shovel, cover it up with sand, mix it around with water and when the sun dries it, vegatables will grow."

I never knew vitamins had such magic powers. Maybe I should try planting Flintstone vitamins in the garden this summer instead of seeds.
