How to Supercool Water

How to Supercool Water

Water is usually pretty predictable. At standard pressures it will boil at 100˚C and freeze at 0˚C. However, under special circumstances it might surprise you. Dihydrogen monoxide can become supercooled, dropping below 0˚C while maintaining the liquid phase of matter. Here’s how: Acquire distilled or purified water. Fill an empty bottle with tap water (this

CAUTION: DO NOT ATTEMPT THIS AT HOME Here is an experiment that even the professionals at AstroCamp will not dare to perform. Water can become superheated in a closed system, like that in a microwave, and become extremely dangerous. Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C,

20 Gallons of Liquid Nitrogen in a Pool!

You come into contact with nitrogen every day; it makes up 78% of our atmosphere. While it is very common to find nitrogen in its gaseous state, it is much more difficult to find it in its liquid state. That is because liquid nitrogen is very cold. If it gets warmer than -321°F it turns

DIY: Fascinating Properties of Dihydrogen Monoxide

DIY: Fascinating Properties of Dihydrogen Monoxide

Humans are approximately 60% dihydrogen monoxide. If this is alarming, it might be helpful to know that this is just water. While water is certainly something quite familiar, it has a lot of properties that are very important and they all come from its famous chemical formula, H2O. Let’s take a look and try to understand

How do Geysers Erupt to Over 300 Feet?

How do Geysers Erupt to Over 300 Feet?

Note: This experiment shoots boiling water into the air, and should not be attempted at home without proper training and safety equipment! Geysers are one of nature’s most incredible spectacles. In the most powerful eruptions, water can be shot over 300 feet–or the length of a football field–into the air! The Castle Geyser in Yellowstone

Cloud in a Bottle

Let’s take a look at the science of clouds! Pockets of warm air near the Earth’s surface naturally float up through the atmosphere like hot air balloons. As an air pocket rises, it expands and cools down. This causes the water molecules within it to group together, creating droplets large enough to see. When a
