Question

You have purchased a coconut in the market.by shaking it you found that there is less water in the coconut.can you fill the coconut with water without making a hole in it

Answer 1

YES, but the resultant water inside will not be potable there after, and even stink!

As you know the coconut in most cases is not filled with water inside, especially the matured ones,not due to evaporation in the normal sense, but the water get absorbed/withdrawn back which makes the wet kernel to become more hard and ultimately reaches the state what is called COPRA, the source of coconut oil!

Now, if the water can get reduced, or become totally absent, the same route should be possible to be used to fill the vacant space inside the dry coconut.

The large eye of the husked coconut which we usually pierce to get water to drink through a straw, has a slightly thin skin( like flake of thin cork) and that is porus if you see under a microscope. That can be used to send water inside, by using

OSMOSIS. If a husked semi dry coconut with some water (after removing the headgear- brush like tuft) is kept inside a pail full of sea water with good salinity, it will facilitate slow absorption of water from the pail by the water inside through thin skin the Coconut. By a few days you can see the coconut become heavier and water contents inside having increased.

This is the technical answer. By that time the inside kernel would have started decaying and the “Eyeskin” got destroyed .

If an unhusked dry coconut remains in sea water for “very long time” a few months by stopping its drift, by some obstruction like rock etc, same thing happens, naturally.

. ♦ The husk of coconut is mostly made up of sclerenchymatous cells which are dead.. . ♦ osmosis do not takes place in dead cells.
