Back in college, our professor did not know this, my classmates and I had fun at the laboratory in one of the Science subjects that we had. Anyways, what we did was we made coffee from test tubes and beakers. That is how we are addicted to coffee! Somebody brought those coffee granules and we heated it right there and then. The only thing the professor noticed was the aroma. He thought it was coming from outside the laboratory! So we got away with it. That is how unique our coffee maker was. It was unique and innovative. LOL!
