You don’t need to buy expensive air conditioners to cope with the heat in a short period of time. Instead, you can cool the room by using a few bottles of water and a fan. Freeze several water bottles and place them in front of or behind the fan. After making the “field” air conditioner, you will quickly enjoy the feeling of comfort and coolness!
Steps
Put some ice bottles in front of the fan

Pour 3 tablespoons (50 grams) of salt into each water bottle. The simplest and most compact way is to use disposable plastic water bottles. Pour 3 tablespoons (50g) of table salt into each bottle. Cap the bottle and shake to stir the salt. [1] X Research Source
- You just need to use regular salt available in the kitchen.

Put the water bottles in the freezer. Wait a few hours until the water bottles are all frozen. When the water turns to ice, you just need to take out the water bottle and use it. [2] X Research Source
- Salt lowers the freezing point of water and makes ice colder.
- Depending on the size of the freezer, it may take longer to freeze water bottles.

Stack the water bottles 15cm from the front of the fan. Using a table fan or a box fan works well, but you can use any type of fan. Open the fan and place the water bottles in front. The air is cooled as it flows through the water bottles. You will have “field” air conditioner when you let the fan blow on the ice bottles. [3] X Research Sources
- Place the water bottles far apart so they don’t block the breeze from the fan.
- Place water bottles on a small table in front of a standing fan.
- Do not use fan rotation (if available). Keep the fan blowing on the water bottles at all times.

Put water bottles in the freezer to reuse. When the ice melts, you just need to put the water bottles in the freezer. After a few hours, you can use the fan as an air conditioner again! [4] X Research Sources
- Pre-freeze multiple water bottles so you don’t have to wait for the water to freeze to ice.
Hang the water bottle behind the fan

Cut halfway around 2 empty water bottles 2.5cm from the bottom. Drink 2 bottles of water or pour water into another. Use a knife to cut the water bottle. Hold the water bottle firmly on the cutting board with your non-dominant hand, then insert the tip of the knife into the bottle and cut halfway around the bottle. Do the same for the other bottle. [5] X Research Sources
- Remember to be careful when using the knife.

Drill multiple holes 0.65cm apart above the cut. Use a 0.65cm drill bit for plastic. Make a row of holes around the bottle, 1.5cm from the cut. After drilling the first row of holes, you will drill 2-3 more rows of holes at the top, with each row being 0.65cm apart. [6] X Research Source
- Another way is to use a soldering iron to make holes by melting the plastic.

Use wire or wire to tie the bottles upside down at the back of the fan. Remember to turn off the fan before tying the bottle. Thread wire or wire through the two holes of each bottle. Wrap the string around the fan cage and tie a knot to keep it in place. To secure the bottles, you can tie another string around the mouth of the bottle. [7] X Research Sources
- Tie a bottle to each side of the fan motor.

Put some ice cubes in the bottle and turn on the fan. Open the cut at the bottom of the bottle so you can put ice in the bottle. You just need to arrange for the stones to lie below the holes. Turn the fan on to the strongest setting and point the fan where you want it to cool. [8] X Research Sources
- The fan will draw cold air from the water bottle through the holes you drilled.
- Since the water bottles are attached to the fan, you can use the fan’s rotation mode.

Pour ice water into the bowl. When the ice melts, you will place the bowl below the mouth of the bottle. Open the bottle cap to let the water run down the bowl. Cap the bottle before you handle the remaining bottle. Just keep using the water bottles and just add ice. [9] X Research Source
Tip: Pour the water from the bottle into the ice tray. That way you can save water!
Warning
- Use caution when handling sharp blades. Always point the tip of the knife away from the body.
