Boiling water below 100 degrees celsius

Take a drinks bottle with a metal lid. Place an thermometer inside the bottle and fill it just below the lid with boiling water and place the lid on tightly. Place ice cubes on top of the lid to cool down the water. The water will start to boil in the vacuum just below the lid. Keep placing ice cubes on there to cool the water and see how low you can get the temperature with the water still boiling.
