The Mystery of the Frozen Block of Soda

The Puzzler

RAY: Back in the old days when we were kids, all sodas had sugar in them. The dissolved sugar is what kept the soda from freezing, even if the temperature was below 32 degrees. It would lower the freezing point, just like anti-freeze lowers the freezing point of water.

Nowadays, however, soda machines are filled not only with regular soda pop that's been around forever, but diet soda that doesn't have sugar in it, and will freeze at 32 degrees.

So, you bought a regular soda and I bought a diet soda. And that's why you're a fat bastard.

Who's our winner this week?

TOM: The winner is Karl Lindsay from Russell, Kentucky, and for having his answer selected at random from among all the correct answers that we got, Karl is going to get a 26 dollar gift certificate to the Shameless Commerce Division at our web site,, with which he can get our new unboxed set, The Best of Car Talk.
