Mr. Griffith's Chemistry class, Junior or Senior year (I can't remember which). He was explaining the difference between a heterogeneous and homogeneous mixture. "A heterogeneous mixture is one that does not blend smoothly and in which the individual substances remain distinct. A homogeneous mixture has the same composition throughout, and always has a single phase..."
Just then, a kid in the back of the class threw up. It sounded like someone dumped a bunch of mini M&M's in the floor. Without looking back, I raised my hand and asked, "Would that be an example of a heterogeneous mixture?"
There were few moments in my high school career where I was quick witted enough to rise to the occasion. I was proud of this one! Unfortunately, everyone was too grossed out by the vomit to notice...
