It's not at all about the tap. It's about the yellow spot. The bigger it is means it riped naturally on the ground longer while still attached by the stem. Those are the sweetest watermelons. That info is gold and I can't believe I just gave it away.
Watermelon test for audiophiles!
Hey,
In this hot and perfect watermelon season (where lots of them are really tasty and sweet), I was wondering if audiophiles can actually pick up a PERFECT watermelon just by tapping it and listening to the tap. If one can hear differences between different cables, it's a lot easier task to listen to watermelon tap. Or on the other hand, if you can't tell which watermelon is perfect by tapping, how come you can hear differences in wires or cables?
