As we all know, salt water is not drinkable and consumption of water packed with salt can make the situation worse. But, if you don’t have access to drinkable water and you have access to salt water, you should know that you can easily make drinkable water. The process that allows this is known as desalination or removal of dissolved salts. In this way, you can create water that is perfectly safe for drinking from brackish and/or seawater. We should not forget that the Earth’s surface consists of 71% water and about 97.5% of it is salt water. Now let’s see how you can make salt water drinkable.
Now let’s experiment. To start with, you will need a bottle filled with seawater. If you don’t live close to a natural source of salt water you can use a bottle filled with tap water and salt. In order to finish this task you will need a large glass bowl and a heavy ceramic mug. Of course, if you don’t have access to these items you can always improvise. The ceramic mug will serve as a container for the drinkable water and the glass bowl will support the process of desalination. In addition, you’ll need a small piece of plastic wrap that can cover the glass bowl. Don’t forget that this process must take place in an area exposed to direct sunlight so you can warm up salt water and make humid air. After that, this humid air will condense and create drinkable water droplets.
So, place the ceramic mug into the glass bowl and fill the bowl with salt water. You should cover about one inch from the bottom of the mug with salt water. After that, cover the glass bowl (and the mug) with a layer of plastic wrap. Before that, make sure that the mug is completely clean. When you are placing the wrap, make sure that there are no holes. Try to make it airtight.
Next, put the bowl in sunlight. If you are at home, put it next to the window in the room that is most exposed to sunlight throughout the day. Place the DIY device on a flat, even surface. If you leave the device like this, the water will condense everywhere, so this is the reason why you need to put a small rock or some small weight right above the cup. In this way, the condensed water will start dropping in the cup.
In order to get a decent amount of drinkable water, you will have to leave the bowl and the mug exposed to sun for about four hours. You can’t expect to get large amount of water, but this is a system for emergency situations. Of course, you can use this model to create much larger systems that can provide more water. If you are curious about the salt, you should know that the salt will remain in the bowl, but this time the salt water will be more concentrated than before.
