Its more than this - its that the model of balancing the weight of water with the vacuum pressure being the siphon limit is not correct.<p>This paper shows an alternative model is more likely to be correct. It is that the water boils easily at low pressure, and that is the limit of siphon height.<p>By careful preparation (degassing), boiling is prevented. Which here allows the column to be raised about 10m.<p>A &#x27;law of physics&#x27; has been modified. This is pretty cool!
