Hi, I'm Tom Scott. These are some of the things I've made and done. They'll probably come back to haunt me in a few years' time. (Want to get in touch about anything? Use the "contact me" link below, not YouTube messages!)

G-Forces, Gliders, and Graveyard Spirals - - Time to learn about graveyard spirals, while trying not to be in one! I was so far outside my comfort zone for this. Thank you to Bruce Duncan from the Edinburgh University Gliding Club, who got me safely up and down again, and to Alistair Hammond from the Loughborough University Gliding Club, who managed to talk me into experiencing serious G-forces for the first time in my life! We launched from Bicester Gliding Club. I'd seriously recommend giving it a go if you can!

Sinking Ship Simulator: The Royal Navy's Damage Repair Instructional Unit - with many, many thanks to the Royal Navy and everyone at HMS Excellent! How do you train sailors to save a sinking ship? Sure, you can teach them the theory, but there's no replacement for having to hammer softwood wedges into deck and bulkhead splits that are spraying cold, high-pressure water in your face. At HMS Excellent in Portsmouth sits Hazard, a Royal Navy Damage Repair Instructional Unit (DRIU). Every Navy recruit who's going out to sea will have to go through something like this -- and on a much harder level than we did! But then, they'll have...

Big Industrial Simulators in Finland

Mevea Simulation sit in Lappeenranta in Finland, and they may well make the greatest industrial simulators on Earth. I had to go check them out. They're at BEHIND THE SCENES on the Park Bench: And no, this isn't a sponsored video: I found out about them, emailed them out of the blue, and they were nice enough to agree to show us around and use their contacts to get us to the steelworks! (See the behind the scenes video for more!) SOCIAL STUFF: Twitter: Facebook: Instagram: Thanks to Matt Gray for directing! Twitter: Facebook: Instagram:

Ships, Mines and Magnetism - - This weekend, the Royal Navy was offering public tours of HMS Defender, one of their new-generation Type 45 destroyers. It's an astonishing ship: about 8,000 tonnes of steel and high-tech equipment designed to defend an entire fleet against air and missile attack. There's another type of attack it's more vulnerable against, though: the sea mine. And by luck, there was a good example of mine defence docked a little way upriver...

700 Flavours of Soda Pop: Galco's in Los Angeles

Welcome to Galco's Soda Pop Stop, and the wonderfully knowledgeable John Nese. Thank you to John for his time, and to all the team at the Soda Pop Stop! You can visit them here: In Highland Park, in Los Angeles, sits something that most business analysts would say couldn't exist any more: an independent store selling soda pop. 700 flavours of it. There was so much I couldn't include in this thanks to my dodgy camerawork -- the create-your-own soda section, John's absolutely perfect recommendation for a soda I'd like. But hopefully I got all the important parts! If you're...

Controlling An Airport From 80 Miles Away

London City Airport's getting a new control tower: but it's just going to be a large mast with 14 high-definition cameras on it. The actual tower will be 80 miles away, in the headquarters of NATS near Swanwick. It feels questionable: but is it? Thanks to all the team at NATS: you can find out more about the new tower here: Edited by Michelle Martin, @mrsmmartin London camera by Matt Gray, I'm at on Twitter at on Facebook at and on Snapchat and Instagram as tomscottgo


TechZone ► Perhaps you've heard that lately planes are flying way too slow. After all, if you can launch a Tesla into space, why not make planes a little faster? Some people think that it is the fault of lazy engineers and designers who don't want to create something better. It is an interesting opinion, but the answer to today's question is a little more complicated. So, are you ready to discover why modern aircraft are slow? Fasten your seat belt and put your seat in the upright position. Have a pleasant flight and... let's get it on!

Is It Dangerous To Talk To A Camera While Driving?

I'm visiting the University of Iowa's National Advanced Driving Simulator, to answer a question: how unsafe is it for me to vlog while driving? Is vlogging while driving dangerous? The team at the simulator are the experts to ask.

How The Rosetta Stone Unlocked Hieroglyphics

Thanks to the British Museum! Go help choose their first YouTube series: The Rosetta Stone is one of the most famous archaeological finds in history: and it was the key to cracking Egyptian hieroglyphics. And while it took scholars years to work it out, there was one clue in there that helped unlock everything that followed. After hours in the British Museum, I went to explain...

The World Is Slowly Running Out Of Sand

I never thought of sand as a non-renewable resource, but there's only a limited supply: and to make things worse, it keeps getting washed into the sea. At Cape May, New Jersey, the US Army Corps of Engineers have just finished rebuilding a beach: here's why. Thanks to the folks from the Corps for showing me around! There's more about their project here: I'm at on Twitter at on Facebook at and on Snapchat and Instagram as tomscottgo CAMERA AND DRONE OP: Osprey Perspectives, EDITOR: Michelle Martin, @mrsmmartin And thanks to Elmo Keep for linking to the article that inspired this video!

Calling The Police Doesn't Charge Your Phone Battery

In Slough, outside the headquarters of Blackberry, I talk about an urban legend that's almost true: the idea that calling 999, the British emergency number, could actually charge your phone battery. It's not quite right, but it's close. (It's easy to make fun of Slough. There's no second part to that, it's just easy to make fun of Slough.) WEB: TWITTER: FACEBOOK: INSTAGRAM: @tomscottgo

The Front Falls Off: Glaciers Don't Go Backwards

Glaciologists will find this video obvious. Everyone else... well, maybe I slept through a bit of sixth-grade geography, but I didn't know this, and I reckon I should have done. Pull down the description for more! I'm here because of Chris Hadfield's Generator Arctic - go check out everyone else who was on the trip, and have a look at tickets for their show at Massey Hall, Toronto, on November 12th! Thanks to all the team at Quark Expeditions - - who made it possible for us to get there, and whose crew and staff on board were just amazing!...

How The Self-Retweeting Tweet Worked: Cross-Site Scripting (XSS) and Twitter - - It should never have happened. Defending against cross-site scripting (XSS) attacks is Web Security 101. And yet, today, there was a self-retweeting tweet that hit a heck of a lot of people - anyone using Tweetdeck, Twitter's "professional" client. How did it work? Time to break down the code. (Remember the old Myspace worms? They worked the same way.) THE SELF-RETWEETING TWEET:

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: • 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,...

Making an International Standard Cup of Tea

As far as I can find, no-one has actually made a International Standard Cup of Tea - ISO 3103 or BS 6008 - for the internet before. Lots of people have talked about it, but that's easy. Making one? That requires precision... and some specialist equipment. You can buy a professional tea tasting set from this Amazon UK affiliate link: Thanks to Morag Hickman for letting me borrow her workshop for last-minute filming! She makes beautiful jewellery, like ring-keepers, dragon necklaces and rings that looks like ocean waves: Update: someone has found an earlier ISO cup of tea on the internet,...

Unexploded Bombs off the British Coast: the SS Richard Montgomery

BONUS PARK BENCH: -- In the Thames Estuary, near a town called Sheerness, a few dozen miles east of London, lies a World War 2 shipwreck that contains over 1,000 tonnes of unexploded bombs. Is it a risk to the area? Or is it just an interesting historical artifact? The trouble is, no-one's quite sure...

Cold Wars, Cruise Ships, and the Northwest Passage

There are a few communities, up in northern Canada, with a dark history and a worrying future. Resolute is one of them, sat at the east of the once-legendary Northwest Passage. In a few years, it might be a tourist destination. Here's why.

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!

7 Illegal Things To Do In A British Election - - Don't worry: unlike last time I did a video like this, I'm not actually going to attempt to do any of these. I swore off politics a long time ago! Purdah also applies to civil servants, who basically can't do anything public for weeks. All the government departments' Twitter and Facebook accounts will be going very quiet... Thanks to Chris Reynolds for camerawork!
