Put water in a sidearm test-tube or in a round-bottom flask with a 2-hole stopper. Insert a
thermometer through a hole in the stopper so that the bulb of the thermometer reaches,
but does not touch, the bottom of the test-tube or flask. Add boiling chips to prevent
bumping. Boil the water and read the temperature on the thermometer. Stop heating.
Connect a water pump to the sidearm or to the second hole of the 2-hole stopper. When the
water stops boiling, turn on the water pump to reduce the pressure. Read the temperature,
heat to boiling and read the temperature again.
