## Crush Your Cans With Science and Recycle!

September 27th is Crush A Can Day and it’s a day to serve as a reminder that we CAN recycle our aluminum CANS! We love recycling and we’ve got a hot way to do it, with the help of science.  This is an experiment we recommend doing at home! All you need is a can,

## Bernoulli’s Principle

Daniel Bernoulli was a Swiss mathematician and physicist in the mid-1700s. He excelled in the fields of statistics and probability, but also was influential in applying mathematics to physical mechanics. Particularly, he is known for his work in fluid dynamics, now known as Bernoulli’s Principle. Most simply, Bernoulli’s Principle is a derivation of the conservation

## Exploring Water

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,

## DIY Chemistry: Coca-Cola and Milk

Mixing different liquids together to see what they taste like seems like a part of human nature. But have you ever mixed your favorite drinks together just to see if a chemical reaction will occur? This is an experiment that you can easily DIY, but we do not recommend drinking it. All you need is

## How Do You Melt Dry Ice?

Dry ice is the solid state of carbon dioxide, the gas we all breathe out, but have you ever seen it in liquid form? When left at room temperature, dry ice doesn’t actually melt; it sublimates, changing directly from a solid to a gas. To understand why, let’s take a look at its phase diagram,

## Bernoulli's Principle Will Leave You Breathless!

What sorcery is this!? Science it turns out! This is a great example of Bernoulli’s Principle! In short, this states that moving air has a lower pressure. Imagine trying to dig a hole in a pool of water: as soon as some of the water gets moved out of the way, the surrounding water rushes

## 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

## Levitate a Soda Can

Did you know that Bernoulli’s principle is a statement of conservation of energy? The sum of kinetic and potential energy is constant in every closed system. In fluid dynamics, potential energy is an expression of the pressure within a volume of liquid or gas. When a fluid moves faster (its kinetic energy increases), pressure (potential

## Make Your Own Cloud Chamber

Clouds usually form when water molecules clump together on small particles of dust in the air. These particles are called condensation nuclei. In clean air, they’re hard to come by, so clouds don’t form easily. If conditions are very humid, the air can become supersaturated, or rich with water molecules that would form a cloud

## Modeling Outer Space

﻿ You’re carrying an awful lot of weight right now. It’s hard to tell, but every square inch of you is supporting fifteen pounds of atmospheric pressure! Multiply that by the number of square inches on the surface of a human body, and you’ll find you’re bearing a hefty load. Atmospheric pressure results from the

## Geyser in a Bottle! Science!!!

﻿﻿ Ever wish you could control the weather? In this experiment, we’ll harness the weight of the atmosphere to make a tiny storm in a beaker! As you read this sentence, the air around you is exerting enormous pressure on your body. Imagine a jacket made of one-inch checkerboard squares. Now imagine that each tiny
