Blowing Air Into Sand Turns It Into a Liquid?

  • Incredible. So what accounts for the scientific result of bubbly liquid-like sand? Well, apparently the process is called “liquefaction” — and it involves the use of air molecules to transform. We love it. We love all cool science. But, what can we do with this? Can we cause a sand castle to melt? Can we trap our enemies as long as our enemies are on the beach and we have a machine capable of providing a lot of air very quickly? We must be careful with such power. In the wrong hands — why — it could be a dangerous thing.
