Salt. Good old sodium chloride, baby. We need it to stay alive. A long time ago, it was very valuable. There was a pretty good book written about it. A guy went viral for sprinkling it while being handsome. But what about when you’re just using it at home? You might use a saltshaker. But that shaker probably doesn’t play music. Or change colors. Or have Bluetooth. Your saltshaker is trash, frankly.
