Drones vs Lightning ⚡

At the University of Manchester's High Voltage Laboratory, we see what happens when a DJI Phantom 3 drone gets hit with an electrical impulse of 1.4MV - basically, a lightning strike. Actually, two Phantom 3 drones. We had a backup. Thanks to the team at the High Voltage Lab! Here's their side of the story: http://www.mub.eps.manchester.ac.uk/science-engineering/2017/04/10/drone-vs-lightning/ And here's a teardown of the drone: http://www.mub.eps.manchester.ac.uk/science-engineering/2017/05/11/inside-the-drone/ The University of Manchester's YouTube channel: https://www.youtube.com/universitymanchester You can also follow on Twitter: The HV Lab http://twitter.com/HighVoltage_UoM Vidyadhar Peesapati http://twitter.com/DrViddy Manchester Energy http://twitter.com/mcr_energy School of Electrical and Electronic Engineering http://twitter.com/eeemanchester Main camera: Fraser Cottrell / http://www.frasercottrell.com Edited by Michelle Martin / @mrsmmartin Audio mix by Matt Gray...

How To Make Parabolic Mirrors From Space Blankets - NightHawkInLight

Parabolic mirrors are useful for everything from solar power to telescopes to holographic projection. They're usually very difficult to make by traditional means, but this video takes a different approach. Check out my sponsor Rayton Solar here: http://bit.ly/Rayton-Solar With their incredible silicon cutting process via a particle accelerator they're able to make solar panels with virtually zero waste and a higher efficiency result. AN OFFERING STATEMENT REGARDING THIS OFFERING HAS BEEN FILED WITH THE SEC. THE SEC HAS QUALIFIED THAT OFFERING STATEMENT, WHICH ONLY MEANS THAT THE COMPANY MAY MAKE SALES OF THE SECURITIES DESCRIBED BY THE OFFERING STATEMENT. IT DOES NOT MEAN...

Making Artificial Earthquakes with a Four-Tonne Steel Ball

In Göttingen, Germany, there's a four-tonne steel ball that can be raised up a 14-metre tower -- and then dropped in less than two seconds, crashing back to earth. It makes tiny, artificial earthquakes: here's why. Thanks to all the team at Wiechert'sche Erdbebenwarte Göttingen! You can find out more about them here: https://www.erdbebenwarte.de/ Three things I had to cut out of this video, because they didn't quite fit into the story or because I couldn't film them: The reason the steel ball survived two world wars is because the university's records listed it by use as a "rock-ball", not by composition as...

Science vs the Weather: Salford's Energy House

At the University of Salford's Energy House, all the energy use is monitored and controlled, allowing researchers to experiment with all sorts of insulation and energy-saving techniques. But how to control for factors like sun, wind and rain? The solution: put the whole house inside an environmental chamber: a building inside a building that means the weather is controlled, repeatable, and part of the science. Thanks to all the team at the University of Salford's School of Built Environment: you can find more about them, and about the house, here: http://www.salford.ac.uk/built-environment/research/research-centres/applied-buildings-and-energy-research-group And they're on YouTube here; https://www.youtube.com/channel/UCe4nyWoHW3jkNXOyqldsHYQ This video edited by Michelle Martin (@mrsmmartin) I'm...

How The Arecibo Telescope Could Help Save The World

The radio telescope at the Arecibo Observatory in Puerto Rico can do something that most radio telescopes can't: it can transmit. And that's useful for something other than sending messages to the stars: it might just help save the world one day.

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!

This Video Is 2D And 3D Simultaneously: the Pulfrich Effect

Hold on tight, because with a stabilised camera shot and a pair of sunglasses, you're about to see a video that works in both 2D and 3D at the same time. The technique's called the Pulfrich Effect, and this is how it works. The BBC's terrible 90s Doctor Who special, Dimensions in Time, can be seen here, complete with its Noel Edmonds-filled framing: https://www.youtube.com/watch?v=NQCeMIQpFBc Camera and sound: Matt Gray / http://mattg.co.uk 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

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.

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,...

Gender Neutral Pronouns: They're Here, Get Used To Them

http://tomscott.com - @tomscott - Grammatical gender is a silly concept. So I'm about to go against my vow of descriptivism, and risk being run over by the Linguistic Mafia's bus, and say this: it's a silly idea. [The line about "the first sentence of the video" is wrong: it's not actually in the first sentence of the video. I cut that line, and forgot about that second line. Whoops.]

Why This “Zero Calorie Sweetener” Isn’t Zero Calories

The final video of this run is from Alex at Technicality Studios! Go subscribe: https://www.youtube.com/user/TechnicalityTime Splenda is a "zero-calorie sweetener", at least in the US.
