Does anyone know of a good but inexpensive water temperature regulator? I was wondering if there is such a thing without spending $600 USD on a regulator and having to hook it up to the pipes in my house.
I seem to recall seeing a device where you would dip a metal prong(?) into a pitcher of water to control the temperature. Is there such a thing? I have no problems letting a device warm/cool liquids to the proper temperature for several minutes while I do other things.
Edit: I'm just doing B&W... no color.
