Could shouting at your coffee actually warm it up
HERE’S THE INTERESTING PART
Whenever you yell at your appliances, you are technically warming them up. Sound waves are mechanical vibrations moving through a medium. When these waves travel, they agitate particles, causing friction that inevitably decays into heat. Of course, the conversion rate is abysmally inefficient. You would have to scream at a cup of water continuously for about a year and a half just to successfully brew a cup of tea.
One discovery leads to another.
