Timed the test. Did the test in my kitchen so no wind. Had to use two cubes to get the water boiling.
First cube burned out at 6 minutes. Water was only 77 Celsius.
Put in a new cub (without stopping the watch) and lit. Water boiled (with big bubbles) at 11 minutes and second cube burned out at 13.30 minutes.
