Chemicals in an Instant Ice Pack |
We say that because Schumacher (already a two-time winner) clearly misunderstood the question; or perhaps we should say that the answer was simply inconceivable to her because of holes in her education. Most people who had taken (and passed) a chemistry class would think of endothermic reactions, those who'd passed physics might think of the effects of pressure on freezing temperature. The J-school grad? Her answers -- such as they are -- are
- Place ice cube trays full of water outside on a day when the temperature is below freezing
- Use a "standalone freezer" (hey -- it's not a refrigerator!)
- Get the ice you need from a "frozen pond or lake."
In case you weren't aware, those are stupid, stupid, stupid answers; especially the standalone freezer crap. Only a total scientific illiterate would think those are sufficient (and Shelly claims to have a BS in Journalism? Really...). Well, here are a few references that will help people who are seeking real answers to this question: The effects of pressure on the freezing (and boiling) point of water can be found in this content from an Illinois physics department. As for making ice from endothermic reactions, heck, you can get an instant ice pack from your neighborhood Walgreens – or perform an experiment to make your own. |
