I like the website HowStuffWorks for some fun information. By accident I found this little tidbit:
*1 16oz (2 glasses ) of ice water will burn 17.5 calories as the body tries to heat up the ice.
*over the course of a day, if you drink 64oz (8 glasses) of ice water, it will burn 70calories.
Of course, don't depend on that for an extra snack or anything, but I thought it was a great motivation to keep drinking our water. And why not switch to ice water and burn a few calories while we are at it?

I'm sure that'll help a lot of other people, though, so thanks for posting it!
