Inside The Giant American Freezer Filled With Polar Ice

Welcome to the US National Ice Core Laboratory in Denver, Colorado, where there's a giant freezer filled with 20km of ice cores from Greenland and the Antarctic. Here's why. Thanks to everyone at the US National Ice Core Laboratory! You can find out more about them here: http://icecores.org/ The Ice Core Laboratory is supported by the National Science Foundation: https://www.nsf.gov/ Edited by Michelle Martin, @mrsmmartin I'm at http://tomscott.com on Twitter at http://twitter.com/tomscott on Facebook at http://facebook.com/tomscott and on Snapchat and Instagram as tomscottgo

G-Force, Jerk, and Passing Out In A Centrifuge

Thanks to the Starrship team for arranging this! I'm also over on their channel, flying with the Blades: https://www.youtube.com/watch?v=iWY3-1gOrxk • At the Royal Air Force training centrifuge in Farnbrough, pilots learn how to avoid G-LOC: g-induced loss of consciousness. Let's talk about g-force, about jerk, and about how to keep circulation flowing to your brain. FAQs: * Isn't 3.6g a really low g-tolerance? * Yep. Turns out I would not qualify to be a fighter pilot. The average range for g-tolerance is 4-6; no-one was expecting me to pass out. The centrifuge team do not deliberately try to G-LOC people! To be fair,...

Tilting an Icy Floor Until You Fall Over: WinterLab

If you're in Canada, you need good winter boots. But how do you know whether they're actually safe, or whether you'll fall over the first time you step on ice? This is WinterLab, part of the Challenging Environment Assessment Laboratories at the Toronto Rehabilitation Institute, where they're testing winter shoes with science. More about the lab and their ratings: http://www.ratemytreads.com/ Thanks to Evan from Rare Earth for being camera op! https://www.youtube.com/channel/UCtGG8ucQgEJPeUPhJZ4M4jA Edited by Michelle Martin (@mrsmmartin) I'm at http://tomscott.com on Twitter at http://twitter.com/tomscott on Facebook at http://facebook.com/tomscott and on Snapchat and Instagram as tomscottgo

The Bizarre Plan to Drain the Mediterranean: Atlantropa

Herman Sörgel wanted to create the largest civil engineering project the world has ever seen: a colossal dam across the Strait of Gibraltar, lowering the Mediterranean sea. There were, of course, a few problems with this.

It costs 70 MILLION dollars per kg! But why?

Sometimes science can be expensive!!! I frequent deal with stable isotopes which can happily reach tens of thousands of dollars per gram. In this case ~$70 000 per gram for 41K. In this case I only had about 1/3rd of a gram. Now it might seem like a lot, but bear in mind this is not really something you can sell. The market for 41K in the entire world is almost nothing. Indeed the only thing that gives it value is it costs so much to make it. Thankfully, this stuff did good work! We got some of...

We Sent Garlic Bread to the Edge of Space, Then Ate It

The title says it all, really. Thanks to Barry from My Virgin Kitchen - go see him cook and test three different garlic breads here: https://youtu.be/jYPYbIO9BLE - and to Steve from Random Aerospace, http://www.randomengineering.co.uk/Random_Aerospace/Welcome.html ! Pull down the description for more details. This started as a conversation in a pub a few weeks ago, and turned into one of the more ridiculous videos I've ever done. We send home-made garlic bread skyward on a balloon; exposed it to the stratosphere, 35km up; successfully returned it to earth in a protective box; and then ate it. It tasted... cold.

A Nuclear Waste Dump You Can Walk On: Weldon Spring, Missouri

In Weldon Spring, Missouri, there is a strange, grey, windblasted seven-storey pile of rocks. It's the Weldon Spring Site: a nuclear and toxic waste dump on the site of an old uranium processing factory. And you can walk on it: it's technically a tourist attraction. That was going to be the whole of my video... and then I did some more research.

Earthquake proof: Japan building made quake-safe by curtain of cables anchoring it down - TomoNews

NOMI, JAPAN — A giant curtain of special cables is the latest earthquake-proofing innovation to come out of Japan, and it combines both functionality and sleek design. With Japan's location along the Pacific Ring of Fire making it prone to earthquakes, citizens are continually finding ways to protect the country's infrastructure. CNN reports that textile company Komatsu Seiren has created threads made from thermoplastic carbon fiber composite, which are braided to form a strong yet flexible rod that's as strong as iron, but 90 percent lighter. The rods have been installed outside the company's building - draping all around the structure and...

Nuclear Fusion Energy: The Race to Create a Star on Earth

If the processes powering the fusion reactor at the Sun's core could be recreated on Earth, it would be one of the most important events in the history of our species. Nuclear fusion power plants could end our dependency on fossil fuels and provide a virtually limitless, highly efficient source of clean energy. We went to two of the world's leading nuclear fusion research centers—Sandia National Labs in New Mexico and General Fusion outside Vancouver—to see how close we are to bringing the power of the stars down to Earth.

Why California's Musical Road Sounds Terrible

In Lancaster, California, there's a musical road. When you drive over it, it plays the William Tell Overture. Unfortunately, it's out of tune. Here's why. Thanks to David Simmons-Duffin, who figured this out about nine years ago: http://davidsd.org/2008/12/honda-needs-a-tune-up/ -- he seems to be the first to have figured out not just that it's wrong, but exactly what happened!

How Zero-G Planes Work

The European Space Agency offered me a seat on their zero-g plane: it's an Airbus A310 that flies parabolic maneuvers, pulling up into the sky and then arcing back down, giving its passengers about 20 seconds of weightlessness (or "microgravity") at a time. Here's how it works. Some people would have filmed their script on the ground, and just messed about while floating. I decided to go for something a bit more challenging. ** If you're a masters or PhD student from an ESA member state, and zero-g sounds like your thing, have a look at the Fly Your Thesis program: http://www.esa.int/Education/Fly_Your_Thesis --...

The Moiré Effect Lights That Guide Ships Home

I'd never heard of moiré effect beacons until I got an email asking me about them. It seemed like a really clever idea - but it was really hard to research. Or at least it was, until I stumbled upon one magic phrase that revealed its history. It turns out this thing's called an "Inogon leading mark" or "Inogon light" -- Inogon, not Inogen -- and it's a Swedish invention from the 1980s. But there's still a question: why is being used to mark an undersea cable, instead of guiding people home? (Full disclosure: there were some weird strobing effects from the...

The Futurama Theorem

The Futurama episode The Prisoner of Benda features a machine that allows two people to switch minds. The problem is that two bodies can only switch minds once. Fry and Co. goes wild on the mind switching machine and have to resort to some serious math to get back into their own bodies. Our mission in this video is to give a crystal clear explanation of the Futurama theorem. As an added bonus there is also some Stargate mind switching action towards the end of the video.

Why European Clocks are Running Slow, and British Clocks Aren't

Many people sent me this story: it covers my favourite topics of power grids and temporal anomalies. But when the mainstream press have already covered it, how could I add something more? The answer: by adding another pet topic, Unnecessary British Patriotism. And a teasmade.

Making Sugar of Lead

Check out my other channel: http://www.youtube.com/c/NileRed2 Oddly enough, many lead compounds have a sweet taste. One of the most famous ones is probably lead acetate. It is highly water soluble and it looks and tastes like sugar. I'll be making it in two ways: 1) Lead oxide + acetic acid 2) Lead metal + acetic acid + hydrogen peroxide Video links: Explosiopedia: https://vimeo.com/111929288 TheBackyardScientist: https://youtu.be/iYj0sSC-NRc Info reference: https://goo.gl/Xg5TRt Music: Neon Stars by Cypher - https://youtu.be/g-EFSA02Yvc ------------------------------------------ NileRed Shop: www.nilered.ca Facebook: https://goo.gl/uyxvJV Instagram: https://goo.gl/z4hFse Twitter: https://goo.gl/uCmnV4 Patreon: https://goo.gl/3h353G
