With any class I teach, I fully anticipate being asked a question that stumps me. Siona was one of my brightest students and challenged me to stretch my brain into an area where logic and knowledge meet up and battle for answers. It was during one such class when Siona asked if we could make vinegar.

When I was in elementary school, my mom packed my lunch every day. I wasn't one of those kids who glamorously got to wait in line for a hot lunch; I was the one with a grease-stained paper bag. On the very rare occasion, my mom would pack up a yogurt cup. I favored the kind with sweetened yogurt on top and jam-like fruit on the bottom.

One man's dream works backwards and ends up forward-thinking.
