Calibrating a thermometer- again, a better description post two.
Fill a glass with ice cubes, then top off with cold water.
Stir the water and let sit for 3 minutes.
Stir again, then insert your thermometer into the glass, making sure not to touch the sides.
The temperature should read 32°F (0°C). Record the difference and offset your thermometer as appropriate.
