Chem lab rocks.

Today, my teacher handed out some white tablets to us. We cut them into small pieces with rusty razor blades. Then, we ground up the pieces with a mortar and pestle. Dust was everywhere, and we cut lines through it with the razor blade to make the portions equal. Losing some would have been terrible. When you get your hands on some, you have to use it well.

It was Alka-Seltzer.

Get your mind out of the gutter.

My teacher was the first to make this analogy, and half the class didn't understand it.
