What is an Electromagnet?
What is an Electromagnet?

Here at AstroCamp, one of our most popular classes is Electricity and Magnetism. At first glance, it might not be obvious how these things are related, but they are actually tied together through important physical principles. To give you some evidence, let me introduce the electromagnet. This is really just a metal rod wrapped with

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

Three Things You Should Know About Telescopes

1) They Come in Three Flavors Image credit: Dale Mahalko. All telescopes fall into one of three categories: refracting, reflecting, or combination. Most modern telescopes favor the reflector method for practical reasons. It’s easier to create and transport a large, precise parabolic mirror than a lens of equal usefulness. Mirrors also eliminate the problem of

Curveball Science

The Magnus effect allows pitchers to throw curveballs, soccer players to bend kicks around defenders, and golfers to launch drives along near-triangular flight paths. This fun physics phenomenon relies on the difference in relative airspeed at various points on the surface of a round object. Viral video captures the Magnus effect in action, 2015. Credit:

Fire Tornado!
Fire Tornado!

Tornadoes are born when extreme weather circumstances come together. Their short, destructive lives are still not fully understood, but one leading theory goes like this: sometimes, winds at different altitudes blow at different speeds, rolling the air between them into a horizontal, rotating cylinder. If a supercell thunderstorm is nearby, the spinning column can be
