Take a look at how ice water makes hot water boil

You can try this at home.
Loukia Papadopoulos

There's no doubt that we are fans of YouTuber Steve Mould as he has a habit of sharing the most entertaining and educational science experiments and explanations and portraying them in a way that is accessible and easy to understand. In this edition of his show, Mould did something that at first glance seems impossible: he used ice water to boil water.

There is one catch, however. You have to start by boiling the water in a microwave. You do that in a glass bottle and as soon as you remove it from the microwave you put a cap on the bottle and close it tightly.

Now, at this point the water is hot but it's not boiling anymore. You then take ice water and pour it over the bottle of water. Low and behold, the water starts boiling again.

Why does this process work? How did Mould conceive of this experiment? What are the scientific principles behind it? Can it work with other types of liquids? This video answers all these questions and offers a glimpse at a DIY project you can undertake at home to amaze your friends.
