Nail In Experiment

During my freshman biology class at North High School in Springfield, Ohio, our teacher was lecturing on the conditions in which bacteria exist. Elaborating on the acidic environment where bacteria thrive, he suggested a simple experiment. "I want you to drop a nail into a glass of Coke or Pepsi, and then observe the acidic reaction on the nail," he said. The girl sitting next to me raised her hand and asked in all seriousness, "Do you mean a real nail, or a press-on?"

Medical Lecture

A lecturer teaching medicine was tutoring a class on 'Observation'. He took out a jar of yellow-colored liquid. "This," he explained, "is urine. To be a doctor, you have to be observant to color, smell, sight, and taste." After saying this, he dipped his finger into the jar and put it into his mouth. His class watched on in amazement, most, in disgust. But being the good students that they were, the jar was passed, and one by one, they dipped one finger into the jar and then put it into their mouth. After the last student was done, the lecturer shook his head. "If any of you had been observant, you would have noticed that I put my 2nd finger into the jar and my 3rd finger into my mouth."
