How To Get Freshwater on a deserted island (without using rain water)-NEED HELP THIS IS FOR SCHOOL??????!!!!!!?
This is the question:
Suppose you were stranded on a deserted island in the Caribbean, with no natural fresh water. Because we know salt water is a mixture, we know it can be separated. How? Remember you are on a deserted island. You can only use what you can find.
thanks
You’ll have to boil the water (wood/ plant leaves, sparks from rocks or friction method of creating fire), use coconuts to collect water for boiling. Steam given off should be pure water, use fabric from clothing held above steam to collect water. Wring out when wet into another container. Sufficiently pure water results.
Also, coconut milk can be used as fresh liquid, but it is a diuretic so can’t be used for too long.

Wholesale Freshwater Pearl Akoya Pearl
Pearls have been prized for their beauty and rarity for more than four thousand years. From ancient China, India, and Egypt, to Imperial Rome, to the Arab world, to Native American tribes, cultures from around the world and throughout recorded history have valued these unique, biologically based gemstones – much longer than any other gem.
The pearl is the only gemstone which is grown inside of a living organism. Pearls are formed within oysters or mollusks when a foreign substance (most often a parasite – not a grain of sand) invades the shell of the mollusk, entering the soft mantle tissue, and picking up epithelial cells. In response to the irritation, the epithelial cells form into a sac (known as a pearl sac) which secretes a crystalline substance called nacre, the same substance which makes up the interior of the oyster’s shell, which builds up in layers around the irritant, forming the pearl.
There are approximately 8,000 different species of two-shelled (bi-valve) mollusks, of which only about 20 types are capable of consistently producing pearls. Natural pearls have always been extremely rare and valuable. Because the layers of nacre tend to maintain the irregular shape of the original irritant, natural pearls which are round or spherical in shape are even rarer still, and are highly prized. Most natural pearls are irregularly shaped.
In a completely natural state, only a very small percentage of oysters will ever produce a pearl at all. Of the pearls which are produced, only a handful will develop to a desirable size, shape, and color; and only a small fraction of those will be harvested by humans. It is commonly assumed that only one in ten thousand oysters will naturally produce a gem quality pearl. Obviously if we relied only on nature, ownership of pearls would still be relegated to only the wealthiest people in the world, and pearl producing oysters would be on the brink of extinction due to over-harvest. As pearls have been a prized gem by much of the world’s population for thousands of years, this need has led to the development of Cultured Pearls.
In the late 19th and early 20th centuries, however, several Japanese researchers discovered a method of producing pearls artificially. Essentially, the technique involves inserting a foreign substance, or nucleus, into the tissue of the oyster or mollusk, then returning the creature to the sea and allowing the resulting cultured pearl to develop naturally. This practice was quite widespread harvesting Mabe pearls. Kokichi Mikimoto is credited with perfecting the technique for artificially stimulating the development of round pearls in Akoya oysters, receiving a patent for this technique in 1916. Although patented in 1916 this technique has since been improved upon and used extensively throughout the pearling world – no longer simply used to cultured Akoya pearls, but freshwater, South Sea and Tahitian pearls as well.
Mikimoto’s discovery opened the door to a greatly expanded pearl industry, in which pearls could be farmed like an agricultural crop, rather than simply sought hit-and-miss. These cultured pearls could now be produced in sufficient quantities to make them available to virtually anyone.
The cultured pearl industry has now far surpassed that of the natural pearl industry. Although a market still persists for pearls gifted to us by nature, these pearls are becoming more and more difficult to find, with rare full strands being auctioned for hundreds of thousands of dollars. Today, purchasing a Pearl Necklace from nearly any store in the world means purchasing a strand of cultured pearls.
