How do you turn salt water into fresh water at home?

You can turn saltwater into freshwater at home using a simple solar desalination method.

Desalination at Home: A Step-by-Step Guide

This process utilizes the sun's energy to evaporate the saltwater and collect the resulting freshwater condensation. Here’s how you can do it:

Gather your materials: You’ll need a bowl, saltwater, a smaller cup, and some plastic wrap.
Set up the bowl: Place the smaller cup inside the larger bowl. Ensure it is positioned so that it will not float or tip over.
Pour in the saltwater: Carefully pour the saltwater into the bowl, making sure not to get any in the small cup.
Cover the bowl: Tightly cover the bowl with the plastic wrap, creating a seal.
Create a slight depression in the plastic wrap: Place a small weight (like a pebble) on the plastic wrap, directly above the small cup, creating a slight depression. This will ensure the condensation will collect and drip into the smaller cup.
Place the saltwater bowl in direct sunlight. This will heat the water and cause condensation to form on the plastic wrap.
Collect the freshwater: As the water evaporates and condenses, freshwater droplets will drip from the plastic wrap and into the cup. This allows you to slowly collect fresh water.
Be patient: This method takes several hours, so be patient while waiting for enough freshwater to collect.

The amount of freshwater you obtain will depend on the intensity of the sunlight and the duration of exposure.
Using a dark bowl will help to absorb the heat better.
Ensure your cup is clean to avoid contaminating the fresh water.
This method is suitable for small-scale desalination and isn't a quick fix for large quantities of water.

By following these steps, you can turn saltwater into fresh water using the power of the sun.
