There are these types of puzzles called water pouring puzzles.
I know it's kind of weird...but I like to take cold showers :) That is interesting, did you know that the original showers were common natural formations? I didn't know that, I bet it was cold as well. Once you get used to them, they are actually quite nice for waking you up If you think so. Were you aware of early signs of Egyptians having shower rooms where servants could bathe them indoors? I did not know that, but I'm not surprised. I'm not sure when the first person got that bright idea, but it was probably far, far back Well, I am not sure either. One thing I know is that ancient people reproduced these natural phenomena Hah, probably! Anything else interesting you know?
Water pouring puzzles (also called water jug problems or measuring puzzles) are a class of puzzle involving a finite collection of water jugs of known integer capacities (in terms of a liquid measure such as liters or gallons).
