This is ice, which I found in our bath tub this morning as I was getting ready for work. The ice is from having left our faucet dripping, as the news reporters always suggest. Apparently this is only useful to a certain temperature below ) fahrenheit. At present, it's 8:35 AM and still -5 degrees F outside. I just keep loading and reloading the weather forecast for next week, when highs will be in the 70s.
I must remember this in August when we've been sitting at over 100 degrees for several weeks.
