Last week my chemistry teacher told us all to get lab coats and goggles. And this year we were going to have droppers in the reagent bottles. Yes yes, this year things were going to be safer in the chem lab. So on Tuesday we all walked to the lab, coat-clad, feeling proud. The chemistry lab has the aura of funeral meeting. It is deadly quiet even when a class of forty-two is inside. Then the once friendly chemistry teacher turns severe. She begins to talk in a hard stony voice. “You will not talk to anyone.
