For this video I went off the coast of South Australia to an island frequented by great white sharks. Here they hunt seals and fish. I've never been scuba diving before but I got into a cage and filmed the sharks under water. It was an incredible experience. Then we came back on the surface to tag the sharks.

I used a nitrogen membrane and Stirling cryocooler to liquefy nitrogen out of the air. For this video I partnered with Starbucks to celebrate their Nitro Cold Brew. Order one here: https://starbucks.app.link/derekmuller

Making liquid nitrogen is hard - in fact up until 150 years ago scientists doubted whether it was even possible to liquefy nitrogen. In 1823, At the royal institution in London, Michael Faraday first produced liquid chlorine, kind of accidentally by putting it under high pressure. He similarly liquefied ammonia.

Borrowing a mixture from Thilorier in France, a combination of dry ice, snow and ether, he reached a temperature of -110C. By 1845 he used this mixture plus a hand pump to pressurize gases to liquefy all the known gases except six, which included oxygen and nitrogen. These became known as the “permanent” gases.

A French Physicist Aimé compressed oxygen and nitrogen in tanks and then lowered them into the ocean over 1.6km deep, where the pressure got up to 200 atmospheres. Still the gases didn’t liquefy.

Only at the end of 1877 were the first droplets of liquid oxygen and liquid nitrogen produced, by Cailletet in France. He first tried oxygen by compressing it up to 300 atmospheres, cooled to -30C, but that wasn't even enough to liquefy oxygen. But when he suddenly released the pressure, the expanding gas cooled, he estimated to -200C and he saw a mist and then droplets slide down the walls of his vessel.

It's amazing how far we've come in that now I can purchase a helium-based cryocooler. It compresses and expands the gas to absorb heat from the tip of the cold finger and eject it into the surroundings at ambient temperature.

Evidence Facebook's revenue is based on fake likes.
My first vid on the problem with Facebook: http://bit.ly/1dXudqY
I know first-hand that Facebook's advertising model is deeply flawed. When I paid to promote my page I gained 80,000 followers in developing countries who didn't care about Veritasium (but I wasn't aware of this at the time). They drove my reach and engagement numbers down, basically rendering the page useless. I am not the only one who has experienced this. Rory Cellan-Jones had the same luck with Virtual Bagel: http://www.bbc.co.uk/news/technology-18819338

The US Department of State spent $630,000 to acquire 2 million page likes and then realized only 2% were engaged. http://wapo.st/1glcyZo

I thought I would demonstrate that the same thing is still happening now by creating Virtual Cat (http://www.facebook.com/MyVirtualCat). I was surprised to discover something worse - false likes are coming from everywhere, including Canada, the US, the UK, and Australia. So even those carefully targeting their campaigns are likely being duped into spending real money on fake followers. Then when they try to reach their followers they have to pay again.

And it's possible to be a victim of fake likes without even advertising. Pages that end up on Facebook's "International Suggested Pages" are also easy targets for click-farms seeking to diversify their likes. http://tnw.co/NsflrC

The aurora borealis or northern lights is one of the most spectacular natural displays on the planet. Theories about its origins have been debated for centuries and common misconceptions persist that the aurora is the sun's rays scattered off ice crystals in the high atmosphere. In truth, the light is created more than 100km above Earth's surface as high speed electrons and protons ejected from the sun in a solar flare or coronal mass ejection collide with air molecules in the upper atmosphere. The charged particles from the sun excite air molecules which then de-excite by emitting light. The display is most common around the north and south poles because the Earth's magnetic field deflects the solar wind from the equator to the poles. Here the magnetic field dips towards the Earth's surface, channeling the charged particles into the atmosphere.

What happens when nylon rope is wound around a spool and pulled horizontally to the right? Will the spool go to the right, to the left, or does it depend on how the rope is pulled?

This is the sixth track from the album Karl Jenkins & Adiemus The Essential Collection, 2006. This is from Jenkins's piece Requiem.

This song seems to reflect a earlier time in my life. An age when people were happier just being themselves. If it wasn't on the news, then we didn't know about it and no one had to worry about offending one another. People smoked in the supermarket, and at the ballgame, and on the airplane and no one ever complained. And just for the record, I inhaled a lot of that second-hand smoke.

Letra: (Daniel Calveti y Rojo)

que piense en ti esta sociedad,
que piense en ti aquel que viene y va,
que digan que tu eres el Señor,
que piense en ti toda mi ciudad

De Norte a Sur
que las naciones bajen un pedazo de cielo,
que abrasen la humanidad
De Este a Oeste
que los gobernantes digan
que la paz se encuentra solo en Ti
Tú eres esperanza
eres medicina
y nuestras crisis en ti encuentran la salida

que piense en ti esta sociedad,
que piense en ti aquel que viene y va,
que digan que tu eres el Señor,
que piense en tu toda mi ciudad
que digan que tu eres el Señor,
que piense en tu toda mi ciudad
ahhhhhh
ohhh

De Norte a Sur
que las naciones bajen un pedazo de cielo,
que abrasen la humanidad
De Este a Oeste
que los gobernantes digan
que la paz se encuentra solo en Ti

Tú eres esperanza,
eres medicina
y nuestras crisis en ti encuentran la salida

Eres esperanza,
tú eres medicina
y nuestras crisis en ti encuentran la salida
uohhhhh que piense en ti toda mi ciudad
que piense en ti esta sociedad,
que piense en ti aquel que viene y va,
que digan que tu eres el Señor,
que piense en tu toda mi ciudad

que piense en ti esta sociedad, Jesús,
que piense en ti aquel que viene y va,
que digan que tu eres el Señor,
que piense en tu toda mi ciudad
