There is a famous demonstration where boiling water or coffee is drunk‚ the trick is it was in a vacuum chamber where it boiled at room temperature. The actual definition of the boiling point of water is the temperature

The problem in the video is that Nestle is essentially gaining an astronomical profit from something that is not only free from our earth but they’re selling it to consumers for a substantial price.
