Boiling water freezes in airhttps://peda.net/id/dea4ca3eef62017-02-10T09:45:19+02:00Samuel Palovaarahttps://peda.net/p/samuel.palovaaraIn some <span>situation </span>boiling water freezes faster than cold water because it evaporates faster and then there is less water to freeze. <br/>

2017-02-10T09:45:19+02:00Aloitustekstihttps://peda.net/id/822c2572ef62017-02-10T09:42:44+02:00We did an experiment where we threw boiling water in to the air. If its cold enough the water evaporates in midair and creates this beautiful pattern. It was -20°C. <br/>
<em><span>"The water is not "freezing in mid air" as these videos so often describe. </span><b>It's actually doing the opposite - it's evaporating into water vapor.</b><span> This then very quickly condenses in the cold air as a cloud of visible "steam" (micro-droplets of water) which </span><em>then</em><span> very quickly freeze into a dust cloud of tiny ice crystals, because they are so small. The actual boiling water does not freeze instantly, and in most of the videos you can see and hear it splattering on the ground."<br/>

Add you own text in new blog entry. Explain what we have done and why. You can do videoclip of that if you want. But in English.<br/>
<br/>
How is it possible that boiling water can <span>freeze up</span> so quickly?<br/>
