A vacuum device can actually blend oil and water
Impossible is possible.
People often use the expression "those two mix like oil and water" to describe two people who don't get along. It's surely not a bad analogy as it's true that oil and water won't mix right away. Have you ever wondered why oil does not dissolve easily in water, despite the fact that so many other liquids do?
To put it simply, water molecules are polar, which means they have one end slightly negatively charged and the other slightly positively charged. The molecules can form hydrogen bonds and bind to other polar molecules, such as water molecules, thanks to these charges. Non-polar oil molecules, on the other hand, are unable to establish hydrogen bonds. When oil and water are mixed in a container, the water molecules cling together while the oil molecules stick together, resulting in two different layers that don't mix.
However, there are some devices out there that can actually mix oil and water. In this video, the Action Lab demonstrates how a vacuum can help oil and water make a stable emulsion. If you're curious to know more, make sure you watch the video embedded above, and as always, enjoy.
