Why does the hot water squirt out of the pipette? Can you explain the Science behind this phenomena? First observed by Lucas, and brought to my attention in a Science class. When cold water is drawn in a soft plastic pipette, and the pipette turned upwards, not much happens, as expected. BUT when hot water (like 90 degrees celsius) is drawn up in the pipette, when the pipette is turned upwards...the water flows and then dramatically squirts out (upto 1 metre away!) The footage is so fascinating you can watch it over and over again. It's also fascinating, because the scientific explanation is not straight forward. Different people will have different ideas and explanations for 1.Why does the hot water flow more readily then the cold water. 2. Why does the hot water squirt out? 3. Where does the energy come from to propel the water? This video could start flame wars as people argue their point of view. What is YOUR explanation?
