How to tell if a watermelon is sweet

You can also tap the watermelon and listen to the sound. If you tap the watermelon gently with your fingers and it makes a crisp "dong, dong" sound and your hand feels a vibration, then the watermelon is ripe and tastes sweet.

If the sound sounds muffled and there is no vibration, the watermelon is generally not yet mature.
