Ray's Wife Proves He's All Wet
RAY: This week's puzzler is from the realm of home repair and maintenance.
My wife and I have had a long-standing debate about drinking water. One result is that we now have an under-the-sink filter, and a little spigot on the sink that dispenses just drinking water.
TOM: I think that's bogus.
RAY: I do too. In fact, I think all those things that come through your tap, like the cyclospora, arsenic, fecal-coliform and mercury are probably good for you, and help build a nice strong immune system.
Anyway, the filter is kind of a pain in the neck to change, because it's underneath the sink, and it's got a big canister. So, I always avoid changing it.
She says to me one day, "The filter needs to be changed."
I say, "Well, how do you know? I turn it on, water comes out, it tastes good and it seems clean. I can't tell that there's anything wrong."
She says, "I know it needs to be changed. It's supposed to be changed every year, and it's been two years."
Still not convinced, I said, "Look, if it weren't working, no water would come out."
She responded, "I know it isn't working, because the water isn't cold anymore. That's the sign that the filter needs to be changed."
So, I reluctantly get under the counter, spend half an hour getting saturated, and put the new filter in. I open the spigot, and it works.
She says, "See? The water is colder!"
And that's my question is this: How is a new filter refrigerating the water?
Think you know? Drop Ray a note!
