Hack away at the top...
Until you see a hole...
Drain into a glass and enjoy now or chill for later.
Halve the coconut...
Scoop out the sweet, tender meat and enjoy!
Good news: coconuts are free and everywhere on Guam! It's a great local food source on Guam. Coconut water makes a great sports drink with potassium, magnesium, and sodium. (Don't have more than one or your digestive system will not like you.)
