As those vortices spin out they do so at the frequency of the sound waves inside the kettle, and we hear a whistle. Now go enjoy your tea. Have a tip we should know? Glen is a comedian, writer, husband, and father. He won his third-grade science fair and is a former preschool science teacher, which is a real job. This mechanism is similar to the Helmholtz resonator, a mechanism that causes sound to emanate when you blow the top of an empty bottle. When air is blown over the top of an empty bottle, air inside the neck of the bottle springs up and down, while air contained in the main body of the bottle is compressed and released each time, like a spring.
The teapot also behaves in the Helmholtz resonator mechanism to produce a different sound from the whistle. However, in the teapot, the air blows through the neck rather than the top, and the air within the whistle bounces up and down like the air in the neck of the bottle. These two researchers have enabled us to understand why we hear the whistling sound anytime we use the teapot to make tea or boil water.
With their further research, they could help to design teapots that boils quietly. However, who wants a teapot that will not alert you when the tea or water is boiling?
Currently living and working in California with my Husband and our grumpy cat. I love tea and always try to sample as much local tea when I travel as much as I can.

And multiple types of tea kettles. Why would you want a strainer in your kettle? Well, that depends on how you use your kettle. How To Use A Kettle Properly Once you receive your new tea kettle, make sure you wash it by hand using a gentle cleanser and hot water.
The Boiling Process When you boil water, always ensure the kettle is placed on the right size burner. Pouring For some, carefully pouring a kettle full of boiling water can feel a little intimidating. Tea Kettle Care After each use, the tea kettle should be emptied and washed by hand with warm soapy water, especially if you steep the tea inside the kettle.
To start, fill your new whistling tea kettle with water and place it on the stove on high heat Bring the water in the kettle to the ideal temperature I usually heat to boiling and then let it cool, if my tea requires a lower temperature; it is better to heat to the right temperature only, and not all the way to boiling, but I am lazy While the water is being heated up, fill your tea leaves in the strainer or take you bag out of the packaging and place it in the cup, if using tea bags Once the kettle begins to whistle, remove it from the heat, carefully.
Models such as the Pykal Whistling Tea Kettle with iCool handle feature a stay cool handle, which allows you to remove the kettle from the heat without the use of a pot holder. The next step is to pour the hot water over the tea bag or strainer. You should also keep in mind that certain teas will require a special temperature. Because of this, I recommend carefully reading the instructions prior to making your tea.
The kettle should never be left out on the stove unattended, if you live in a home with small children or pets. Additionally, the fumes from a boiling kettle can be potentially harmful to pets if it has a PTFE coating. The coating can emit fumes that are life-threatening to birds. Another safety issue can arise if your kettle has an aluminum base.
If you have a copper bottom or stainless steel bottom kettle, the bottom of the kettle can become warped or discolored if you allow the kettle to boil dry. Fusing is another safety concern. If you have a copper, silicone-polyester, or enamel kettle, the bottoms of the kettle can actually fuse to the burner on stove tops that are made out of glass, if the kettle is allowed to overheat.
Never drag or slide your kettle on the stove top. What exactly do they like about the electric kettle? Final Thoughts Now you know how to use a whistling tea kettle, and are aware of the important tips for use, safety, and care.
Enjoy this post? Please share Forget what the fox says. Until recently, the bigger mystery was why the kettle whistles. The high-pitched note emitted by hot kettles has puzzled scientists for more than a century, but thanks to two steamed-up researchers at Cambridge University, the exact physics of a whistling kettle have been worked out.
We've long known the basics, of course, that a whistle is caused by the vibrations of pent-up steam escaping a small opening, similar to a person whistling. Anurag Agarwal delved deeper, examining how the two holes on a standard kettle whistle cap specifically interfere with the steam. Steam produced by the kettle first meets a hole in the kettle's spout, which is significantly narrower than the spout itself.
