How can you tell if watermelon are sweet from looking at the outside?

We all love watermelon. It is one of the most favorite fruit to eat during hot summer days. Its flesh is sweet and cold and can help to quench your thirst. When looking for which watermelon to buy we all want a ripe one. Well how can we tell if it is ripe? The stripe. the darker the stripe, the sweeter it is. Another way to know, is to knock on it. If you can hear a hollow sound, then that one is ripe and sweet. Its yellow butts is also an indication of its ripeness. If you somehow get an unsweet one, just dip it in salt. It will taste sweet. 

Well enjoy your juicy watermelon. It is fecalicious !
