The world of snakes is pretty mysterious: maybe you fear them, love them, or respect them from afar, but we can't help but wonder what is it about snakes that makes them so fascinating? Join us for a fun SciShow compilation of everything...

Venomous snakes produce some of the world’s deadliest substances, so they have to be pretty careful about how they use it. But what happens if they accidentally inject themselves with their own harmful cocktail?

We all know the words around electricity -- _charge," _positive," _battery" and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena.

What is it about snakes that intrigues us so much? Is it their deadly venom, their spongey mouths, or their international travel?

A lot of ionic compounds dissolve in water, dissociating into individual ions. But when two ions find each other that form an insoluble compound, they suddenly fall out of solution in what's called a precipitation reaction. In this...

In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

You don't have to fight feral ghouls to be familiar with the clicking sound of a geiger counter, but what exactly makes these radiation detecting devices click?

If you ask someone to picture a thunderstorm, chances are they will have no problem slipping into a memory of dark clouds and bright flashes screaming out from them. But, incredibly, they’re probably picturing the tame version of...

We've all had the experience: you're walking across a soft carpet, you reach for the doorknob and - ZAP. But what causes this trademark jolt of static electricity? Anuradha Bhagwat sheds light on the phenomenon by examining the nature of...

You just wanted to shuffle across the room in your pajamas and bunny slippers, but when you go to reach for the door knob... you get shocked! What gives!? What causes this strange effect?

Hank shows us another SciShow: Experiment! This time he's tackling what may be the most cliche, well-known and misunderstood experiment of all time: the lemon battery. The take home message in this one is: the electricity is NOT in the...

Vinegar may have a powerful smell, but did you know it's actually a weak acid? In the chemical economy, acids actively give away their protons while bases actively collect them -- but some more aggressively than others. George Zaidan and...

Isoelectric focusing (IEF) is a high-resolution protein separation technique that separates proteins based on their isoelectric points (pI) using a pH gradient in an electric field. Proteins migrate to the region where their net charge...

The photoelectric effect is a phenomenon where electrons are emitted from a material, typically a metal, when exposed to light. This effect supports the quantum theory of light and demonstrates the particle-like properties of...

It may seem counterintuitive, but draining the battery to 0 to 1% before recharging it again, is not a good practice. One simple hack to improve your battery life (for Li-ion batteries) is to use the 80:20 rule. Charge your battery to...
