Cordless Anti-static Bracelet, Garbage or Junk?

Hi, Melvin asked me on Twitter if it is possible to make a bracelet that removes the static electricity from body and avoids shock Of course, there are these straps that ground the body and remove static electricity But is it possible to make a cordless one? And surely after I did a quick search, […]

Definition of Voltage and Current (ElectroBOOM101-002)

Hi, now that you know the most accurate theory of how electron came to life, let’s get into electronics, but not quite yet. I can’t just tell you what the voltage and current are – the video would be too short. You won’t quite grasp the meaning. So when scientists were discovering electricity, they already […]

Lec 06: High-Voltage Breakdown and Lightning | 8.02 Electricity and Magnetism (Walter Lewin)

Last time I mentioned to you that charge resides at the surface of solid conductors but that it’s not uniformly distributed. Perhaps you remember that, unless it happens to be a sphere. And I want to pursue that today. If I had a solid conductor which say had this shape and I’m going to convince […]

Sparks from Falling Water: Kelvin’s Thunderstorm

So the people from the Hunger Games came to me and they asked me if I wanted to do an experiment that would be related to power generation. And strangely, there is this one idea that I’ve been thinking about for years, and now finally I have the chance to do it. Come check it […]

Get a More Precise Cut With the AirForce 27i Plasma Cutter

– Spark your imagination with the AirForce 27i plasma cutter. Weighs only 28 pounds. MVP technology allows the AirForce 27i to run on 120 volt or 240 volt input power without the use of tools. Up to 27 amps of power. Spark your imagination.

Electricity Can Kill You!

Some friends ask: “Isn’t it the electrical current that kills you?” Well yes, but the voltage needs to be high enough to generate enough current. Something that’s capable of generating hundreds of amps doesn’t necessarily hurt you. For example, a capacitor like this one can generate a lot of current. And right now it’s charged […]

Bill Morrison | Electricity — Behind the scenes

I wouldn’t call it modern material but it is, in some ways, dealing with a modern theme, a theme that we still are all quite beholden to: energy, power, electricity, how we make it work for us. I think that it heralds a new age that we all can identify with. This material was an […]

5 Crazy Science Stunts You Can’t Try At School

Grab your safety gear and sign the waiver, because we’re exploring 5 insane science stunts you won’t be learning at school. Normally we don’t think of metals as being very dangerous. We use them all the time, but sodium metal is one that’s extremely reactive. The second it touches water, it starts ripping the water […]

Fun with ultracapacitors!!

In this video we’re going to commit random acts of destruction and learn a few things about capacitors along the way. Recently “Electronic Goldmine” had a good price on some ultracapacitors and I bought a lot of them. Ultracapacitors are like regular capacitors except they can hold much more energy. Here’s an example: This is […]

The Metal Melter

I’ve just modified this Microwave Oven Transformer into a dangerous little device. 800 amps of electrical current is about to be bad news for anything made of metal. Today I’m in the mood to melt some metal. This Microwave Oven Transformer used to be a dangerously high-voltage device, but I modified it so the voltage […]
