Product Description
No, this will not tell you when it's time to go to the dermatologist. But it will tell you that your water is boiling on the stove. Tired of having the pasta water all over the stove top? Do you like hard boiled eggs but hate to mop up the water? When the water reaches a rolling boil, this round piece of glass will start to "dance" on the bottom of the pot. Gee, glass on metal or glass on glass, there will be enough noise to let you know to turn down the stove. Price includes shipping and handling.
