Summer weather can be sweltering, causing people to sweat easily, especially after working or exercising, leaving the body in a state of dehydration that requires drinking plenty of water.

It can be particularly agonizing to see a bowl of steaming hot water when you're thirsty but unable to drink it.

Today, let's explore four clever tricks to quickly cool down boiling water, especially the last one, which can cool water in just a few seconds.

1. Two-Bowl Method: Prepare two bowls and pour hot water into one. Then slowly pour the hot water from one bowl to the other. If you have an electric fan, use it to blow over the bowls. Repeat this process several times, and the water in the bowl will cool down easily.

The principle behind this method is the back-and-forth pouring between two bowls, which promotes the flow of hot water, allowing heat to dissipate rapidly and thus cooling down the water.

2. Stirring with a Stick: Use a larger bowl and pour hot water into it. Then stir the water with a stick. For quicker results, place the bowl in front of a fan and stir while the fan blows air over it. This accelerates the movement of hot water, aiding in rapid heat dissipation. Soon enough, the water won't be scalding hot.

3. Saltwater Bath: Pour boiling water into a cup. Prepare a basin with cold water and add some salt, stirring until the salt dissolves. Then place the cup of hot water into the saltwater bath for a few minutes. For a faster result, pour only half a cup of water into the cup and gently shake it in the basin, being careful not to let the cold water into the cup. This method takes about 30 seconds to cool the water.

The principle here lies in the different specific heat capacities of saltwater and plain water. Saltwater has a lower specific heat capacity than water, meaning it conducts heat more effectively. By placing the hot water into saltwater, the high temperature decreases rapidly, effectively cooling the water.

4. Instant Cooling Bottle Method: If you feel the previous methods take too long and you can't wait, here's a method that can turn boiling water into warm water in just a few seconds. Prepare a bottle with a lid at home and pour hot water into it to cool. When you want a drink, pour a small amount of boiling water into a cup, then top it up with cold water from the bottle. In just a few seconds, you'll have the perfect temperature. Isn't that simple?

These four clever tricks to quickly cool down boiling water each have their practicality. Which one do you find most useful? If you think these tips are helpful, feel free to share them with your friends and family!
