Fire-Fighting

It's simply amazing!

A fire can actually be put extinguished with sound waves - more specifically lower frequency sounds.

The basis for this is the compression and disturbances of the air molecules by the sound waves. Fire needs oxygen to undergo combustion. Therefore, the air disturbance disrupts the process.

Similarly, a huge-ass explosion next to a fire will remove the oxygen, thus stopping the combustion too.


Another amazing fact is our memory of past events increases significantly under hypnotism! Imagine how useful this would be in solving crimes which involve witnesses.
