Did you know that you can boil water using ice? In this video, Alex Dainis describes the science behind this unique trick! Water will boil at lower temperatures at higher altitudes, because the atmospheric pressure there is lower. Thus, if you can create a low pressure atmosphere in a jar, you can cause water to boil at a temperature lower than 100 degrees Celsisus. To execute this experiment, boil water in a heat proof jar, then screw on the lid. The water will stop boiling, but when you place ice on top of the lid, the water vapor and gasses inside the jar will cool down, creating a lower pressure atmosphere that allows the water to start boiling again!
