We Liquified a Himalayan Salt Lamp

In today’s video, we are taking a pile of Himalayan salt lamps, and putting them through some stress test to see just what they can and cannot handle. [Music] Guys, ironically enough, just a few hours ago today, Veritasium released a video that debunked whether or not Himalayan salt crystal lamps were actually good for […]

Neutron Star Merger Gravitational Waves and Gamma Rays

Due to the crazy technological challenges that had to be overcome in order to detect gravitational waves, some people were skeptical that scientists had actually done it, that they’d actually seen gravitational waves from black holes – after all, there was no corroboration. But, after the discovery that’s being announced today, there can be no […]

What’s In A Candle Flame?

What is a candle flame really made of? I am at the Palace of Discovery in Paris to do an experiment that beautifully demonstrates the answers. Ok so we’re turning on an electric field here and we see that the flame is spreading out. Thats very cute, it’s like a butterfly. And you can see […]

Is America Actually Metric?

I’m here at the National Institute for Standards and Technology, and I’m about to see some of the original kilogram standards. Is that right? Patrick: You are, you are. When were these made? Well the originals were made in the 1880s. There were 40 of them that were brethren of the International prototype kilogram and […]

What Is Electricity? (Are You Gonna Be My Girl?)

Go!! 1,2,3 a song about ‘lectricty because it powers our lives, makes it possible for us to thrive because it powers our lives, makes it possible for us to thrive Oh, 4, 5, 6, volts of potential difference makes electrons go round if the circuit is complete and sound Circuit’s closed Voltage There Current Flows […]

How Special Relativity Makes Magnets Work

Only a few elements can be permanent magnets – iron is one. Copper is not. But if you pass an electric current through any metal it becomes a magnet – an electromagnet. But how does this work? Well strangely enough, it’s a consequence of special relativity. Special relativity is the fact that in our universe, […]

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 […]

How Do Sharks and Rays Use Electricity to Find Hidden Prey? | Deep Look

We live in a world full of electric fields. Animals, plants — even the earth itself — creates them. But only a handful of creatures can actually sense them. Sharks — also rays and skates… a whole group, animals called elasmobranchs — can actually detect electricity Maybe it’s like feeling the presence of someone hiding […]
