1. Fill plastic bottles with water and add salt

First, fill two or three plastic water or soda bottles with water, and pour three tablespoons of salt (51g) into each. Replace the caps on before shaking each bottle to ensure the salt is thoroughly mixed into the water.  

2. Put bottles in freezer

Next, put the bottles into the freezer, and leave them until they are completely frozen. The salt inside will lower the freezing temperature of the water, making the ice colder. Take the bottles out of the freezer once the water turns to ice.  

3. Place frozen bottles in front of fan

Then, place the frozen bottles right in front of your electric fan, about 6 inches away. Turn on the fan, keeping it pointed towards the water bottles, and the air should feel cooler once it passes around the frozen bottles. A desk/table fan will work best, but you can use any fan that is height adjustable. Simply put the bottles on a table in front of a standing fan. Once the ice melts, simply put the bottles back into the freezer again.You can always prepare multiple bottles in your freezer, so you won’t have to wait for your instant cooling.

And there you have your DIY air conditioner that's easy to make, and will cool you down in a heatwave!

How to make a DIY air conditioner: Hanging bottles behind fan 

Another alternative is to hang bottles behind your fan.

1. First, take your empty, plastic water or soda bottles and cut off the end, about 1 inch (2.5 cm) up from the bottom with a utility knife. Next, carefully punch a row of holes in the sides with a screwdriver or pointed tool.  

2. Then, tie the bottles upside down at the back of your fan with a string or wire put through two of the holes in each bottle. Ensure the fan is turned off before securing one bottle on either side of the motor compartment.

3. Next, fill the bottles with ice cubes just below the holes, before turning on the fan. This will pull in the cold air through the holes, and cool the room.Since the bottles are tied securely to the back of the fan, you can set it to oscillating mode. Once the ice melts, simply remove the bottle cap and place a bowl underneath the nozzle to catch the water. Then you can just replace the ice in the bottles.
