You can also get fairly good results from using boiling water and ice
water for 100 C and 0 C respectively. It helps to put the ice water in a
foam cup with a hole in the lid for the sensor, and leave it sit for a few
minutes to give the water time to reach freezing point. Don't let the
sensor touch the ice cubes, they're below zero. Impurities in the water
may affect your results.
Cheers,
