In light of another coffee riddle, I thought it might be fun to post this story. This'll go fast. True Story: At work one day, Mike had just made a giant cup of hot coffee (as in, he had the whole pot in his giant mug). We got a shipment of something and just to see what would happen, we added some of it to the coffee in his mug. The result smoked and bubbled so much that we had to hold towels under the cup. It was hilarious. Even Mike couldn't stop laughing. What did we add? | ||

was it a chemical compound? dry ice? sodium metal? phosphorus? an acid or base? oxidant or reducing agent? | ||

Reminds me of the story I heard about a stage production which decided to use dry ice and water to create fog/mist, except they figured if they used boiling water it would be even more spectacular. It was, except the cloud immediately descended into the pit, making it rather difficult for them to see the music, the conductor or anything else. | ||

dry ice Yes. Wow. That was even faster than I thought. The bubbling didn't throw you off... have you done this before? ****************SPOILER**************** We added a thumb-sized piece of dry ice to his coffee. The reaction between the two was incredible since there was such a discrepancy between their levels of energy (temperature). The dry ice expanded as it cooled down the coffee and absorbed some of it into itself, meanwhile giant bubbles filled with smoke formed and foamed over and out the top. Whenever we popped one of the bubbles, the smoke would fly out. When the reaction was close to finished, there was a giant hunk of... ice? Dry ice? Coffee ice?... where the pot of coffee used to be. And you folks were complaining about luke-warm coffee! | ||

wow, sorry about that! I always think it's not real science if it doesn't involve colorful, bubbling liquids with plenty of dry ice steam. also, the larger chunks make fantastic hockey pucks. | ||

Two of you got the dry ice connection. Must be something everybody wants to try at some point  Too many people with too much time on their hands. | ||

I have and if you leave it in boiling water, there are moments when there is a crack of air coming outbecause of the reaction, and it freaks people out amazingly because it is so sudden and load. I been meaning to do it on Hallowe'en... | ||

Thankfully no one's ever done this to me, as I'm almost always enjoying some time of coffee drink. About the worst coffee spoiler I've ever seen was when my father-in-law took a sip of his black coffee and noticed some soap suds float up to the surface - apparently the restaurant we were at didn't have a good rinse cycle on the dishwasher? |
