How to do

How to open Coconuts with hand without any tools.     I will show you the method that I use for cracking open coconuts now when you go down to the store and buy a coconut it is already ripped out of the husk for you. But if you live on an island like movie castaway castaway you have to get through the husk in order to get to the coconut but coconut these husks are deceivingly tough .            If you want to open a coconutthey take an enormous amount of energy to rip through and so if you are in a survival situation trying to conserve energy the last thing you want to do is burn it all up trying to get to your source of food. Or else here's a little method that I have played around with to crack these things open using as little energy as possible.            When you give your coconut a good shake you should be able to hear the water sloshing around inside the coconut if you do not hear anything in the coconut maybe it's either chock full or completely emptied
