When the heat outside becomes unbearable and your home starts feeling stuffy, many people look for quick ways to cool down without spending money on air conditioning. It turns out that a simple trick using a frozen bottle of water and an ordinary fan can provide much-needed relief.
Here's how this method can help lower the temperature in your room and create a more comfortable space, according to Onet.
How to make a DIY air cooler
Making this cooling system is incredibly simple. You'll need a regular 1- to 1.5-liter plastic bottle. Fill it about four-fifths full with water (leaving space is important so the expanding ice doesn't crack the bottle) and place it in the freezer.
Once the water is completely frozen, take the bottle out and position it directly in front of a running fan. The airflow will pass over the cold surface and circulate cooler air throughout the room.
One important tip: place the bottle on a deep plate or a towel, as condensation will form while the ice melts and water will drip from the bottle.
Why this hack works
According to experts, melting ice absorbs heat from its surroundings. As a result, the air pushed by the fan becomes noticeably cooler. However, it's important to remember that the effect is local and lasts only until the ice has completely melted.
A complete approach to keeping your home cool
How much of a temperature difference you'll notice depends on several factors, including the size of the room, how much it has already heated up, the insulation of your home, and even how many electrical appliances are running. The more heat sources inside, the harder it is to keep the space cool.
That's why experts recommend using the frozen bottle trick alongside these basic heat-fighting strategies:
- Keep curtains or blinds tightly closed on windows facing direct sunlight during the day.
- Ventilate your home only late in the evening, at night, or early in the morning when outdoor temperatures are lower.
- Limit the use of household appliances that generate significant heat, such as ovens, irons, and clothes dryers.
