Metals & Ceramics: Crash Course Engineering #19

Materials matter. You wouldn’t want to make a stop sign out of candle wax or a bench out of chocolate. Neither would be able to hold up to the weather outside, and things would get quite sticky rather fast. So if you’re going to create things and solve problems, you’re going to need the right […]

Adrenaline is one of the most famous hormones in the animal kingdom and it’s our response to a “stressor.” Stressors can be anything; a sudden scare, […]

Static Electricity and Water

Frostbite Theater presents… Cold Cuts! No baloney! Just science! Hi! I’m Joanna! And I’m Steve! And this is a piece of PVC pipe! And this is a plastic cup that has a hole drilled into the bottom of it. So, when I fill it with water, it leaks out of the bottom. If I charge […]

Should a Person Touch 200,000 Volts? A Van de Graaff generator experiment!

Frostbite Theater presents… Cold Cuts! No baloney! Just science! Now, what’ll happen if a person were to touch it? Or, maybe a better question is, “Should a person touch it?” [Audience] Yes! Well, maybe yes, maybe no. Do you guys know what voltage is? What does voltage measure? It’s actually a measurement of energy per […]

Slower Than a Turtle – The Speed of Electricity

Hello I’m Daven Hiskey and you are watching the Today I Found Out Youtube channel. In the video today we’re looking at the surprisingly slow speed of electricity. Let’s get started. You may be surprised to learn that electrons flow through a typical copper wire much slower than a turtle walks. Each wire that conducts […]

What is STATIC ELECTRICITY? w/ Illustration

Everyone’s had that moment where they walk across their carpet and reach for a door handle, only to be greeted by an irritating shock. This phenomenon is known as static electricity, and a more drastic example can be seen when lightning occurs. Although chemists and physicists are unsure of how exactly static electricity works, many […]

Electricity: Crash Course History of Science #27

Like thermodynamics, the history of electrical physics has its roots in pre-industrial questions that converged in the nineteenth century. These questions became a research paradigm, driven by a whole crew of researchers… And they led to a power system that reshaped the world. Time to get tingly! [Intro Music Plays] The study of electricity goes […]
