Chem for Dogs
I'm not very strong in my comprehension of chemistry (in fact, I'm downright stupid when it comes to chemistry, as anyone who has taken a chem class with me can attest) and so I'm not going to try to explain why this happens (if you're curious, read this) but apparently, not only does salt melt ice, but it also lowers the temperature of the ice as it melts-- somehow the salt uses energy from the water to cause the melting, and when you take away energy, then things get colder . . . but the interesting part of this equation is that I learned this from my dog . . . the other day when it was very, very cold and I was walking him down at the park, he started bobbing up and down like he had Parkinson's, but then I noticed that he was walking on three legs-- he was holding one paw in the air, and I took a look at the paw and it wasn't injured so I just chalked it up to weirdness and in a moment he stopped, but when I brought this up at the dog park, everyone seemed to understand this principle about salt and ice and they all gladly told me about it (I talked to multiple people about this phenomenon, at different times, and everyone I talked to cited the fact that when you make ice cream, you use salt to lower the temperature of the cream . . . does everyone who owns a dog also make homemade ice cream?) and so my first solution to this problem was untenable: for a few days I carried my dog across the street to the park-- because all the salt collects on that patch of pavement-- but my dog is fairly heavy and I walk him a lot, so that got old quick . . . instead, I bought him some Musher's Secret paw wax and that did the trick . . . and now I can proudly say that my dog taught me more about chemistry than that old bat I had in high school.
