Three simple steps to pick a good watermelon:
1. Choose a firm, symmetrical watermelon that is free of bruises, cuts and dents.
2. The watermelon should be heavy for its size. Watermelon is 92% water that accounts for most of its weight.
3. On the underside of the watermelon, there should be a creamy yellow spot from where it sat on the ground and ripened in the sun.
