  • Hey it's me Destin, welcome back to Smarter Every Day.

  • There's only few times in your

  • life when you look at something and

  • you're like: 'You know, this can't be a thing,'

  • But it is a thing!

  • This video is just like that. We're going

  • to look at an invention today by Nikola

  • Tesla, but the thing is, it looks just

  • like a video game, but I assure you this

  • video is real. Before we check that out I

  • want to go look at a couple of

  • contributions he made to society as

  • soon as he emigrated to the U.S. in the

  • 1880s. If you've ever done a

  • patent search on Nikola Tesla you'll be

  • amazed. It's all there! Pumps, guidance,

  • power distribution, fluid propulsion,

  • wireless energy, and a super important

  • one: motors. Tesla created a multi-phase

  • AC generator system that first proved it

  • could work at the Ames Hydroelectric

  • Power Plant in Colorado. This led to Tesla

  • teaming up with George Westinghouse and

  • creating the first large-scale AC power

  • plant at Niagara Falls, which was a huge

  • deal. If you haven't seen, it this really

  • cool statue of Tesla overlooks the

  • Canadian side of Niagara Falls. My

  • favorite part of the statue tells how

  • it came up with the idea of AC power.

  • He said he was walking in a park in

  • Budapest with a friend when suddenly the

  • idea of rotating magnetic fields

  • came to him like lightning so, he drew it in the dust.

  • Speaking of lightning, Tesla carried out

  • incredible experiments with high voltage

  • arcs in Colorado Springs. One such

  • experiment involved making this circuit.

  • There's a power supply which charges a

  • capacitor and when the capacitor fills

  • up in arcs across a spark gap, which

  • dumps that energy into a primary coil.

  • A secondary coil is tuned to the same

  • frequency for resonance, and then boosts

  • that voltage, and there you have it. Lightning.

  • There's a company called One Tesla

  • that makes do-it-yourself

  • Tesla coils that you can buy and assemble

  • all by yourself as long as you know how to solder.

  • My buddy Philip works at a

  • nuclear plant, so since we're dealing

  • with high-voltage, I got him to come over

  • and help me out. These things are super

  • cool and a great place to start if you

  • want to build your own coil. Instead of

  • using a spark gap like Tesla did, this

  • thing uses a really fancy inhibitor

  • circuit that lets you do really cool

  • stuff. You can load MIDI files onto an

  • onboard SD card and it will play

  • whatever song you want.

  • I wanted to hear it play O Fortuna

  • (buzzing in the tune of 'O Fortuna') Whoa!

  • (astonished noise)

  • Obviously, the next step was to try to impress the kids.

  • (buzzing to the tune of 'Super Mario Bros. - Main Theme')

  • (laughter)

  • (tune continues)

  • That is so cool

  • (tune continues)

  • (laughter)

  • after this we started trying to

  • methodically probe the limits of the

  • system to see what it was really capable of,

  • but I got a little too confident, and in my

  • excitement I started to do things with

  • the manual tells you not to do.

  • Looking back at it this is kind of funny,

  • because you can see the exact second

  • when i go from pure geek joy, to instant regret.

  • (rapid, high pitched buzzing)

  • Are you seein' this?

  • Oh it broke!

  • I broke it and I feel bad about that,

  • because I knew what I was doing, I over

  • drove it I probably broke the rectifier

  • or the igbt and I'm sad. It's a DIY

  • coil, though. We can fix it quickly, but

  • instead of working on it why don't we go

  • visit a guy in my hometown, who has a

  • website dedicated to Tesla coils. I

  • found him today, have never met the dude,

  • about to go be best friends with this

  • guy. he's got a little bit larger coil.

  • Let's go get Smarter Every Day.

  • This is Cameron Prince. He runs the number one

  • Tesla resource website on the

  • Internet called teslauniverse.com. He

  • provides tesla coil performances, and he

  • also happens to live directly across the

  • street from my aunt and uncle.

  • This is a little bit bigger than mine.

  • "How big is this thing?" Prince: "Oh it stands about nine foot-tall." Destin: "Nine foot-tall? "Did you build it?"

  • Prince: "I did. It's as big as I could make

  • it and fit in the garage."

  • "Really." "Yeah." "So that was the design requirement?"

  • "Yeah that was the design limitation there."

  • Destin: "Is that a capacitor bank down there?"

  • Prince: "Yeah, that's a big capacitor bank."

  • "Dude! That's not a joke!"

  • Prince: "Those came out of an MRI machine."

  • "Really. Is that the most expensive part of the

  • whole device?" Uhm probably." "And do the cats walk

  • around when you're doing it?"

  • Destin: "That would- It would bake a cat, man!"

  • Destin, narrating: Cameron is the real deal. When I was a

  • kid I collected baseball cards and rode

  • my bike. Not Cameron. His life changed

  • forever the first time he saw a picture

  • of Nikola Tesla." Cameron: "when I saw those pictures

  • of him in colorado springs, in his

  • experiments, sittin' in front of his coil,

  • that lightning going around him

  • and then I was hooked. You know most people were...

  • when they were kids, were throwing baseballs

  • and stuff. I had a box of light bulbs and wires and

  • batteries" Destin: "That's awesome. I like

  • it when people are excited about things.

  • This makes it so much more fun."

  • okay here we go

  • (indistinct speech, snapping switches)

  • (loud buzzing, rising in intensity)

  • Destin: "Holy Cow!"

  • (buzzing continues)

  • 'Ok, I got it! I got it!"

  • (buzzing falls off, Destin laughs) "That is ridiculous!

  • (still laughing) Alright. Alright. That's unnerving!

  • Time out. There are some experiences you

  • cannot convey via internet video, and

  • this is one of those. We're talking

  • 20-foot lightning bolts hitting the

  • ground constantly in front of you.

  • This was unreal. My heart has never gone from

  • zero to a hundred in this short amount

  • of time. It was... whatever. I can't explain it,

  • I'm not gonna try." "I can't explain that!"

  • After I calmed down a bit, Cameron asked me if

  • I wanted to see a real-life Tesla gun,

  • which I didn't even know was a thing!

  • He built this thing from a kit designed by

  • his two friends Steve Ward and Phillip

  • Slowinski. Only a few of these things exist

  • in the world, and I apologize for the

  • laughing here, but I was really, really

  • excited.

  • It doesn't look real; it feels like

  • you're in some kind of video game.

  • "How do you control the power output?"

  • "The display right here." "Dude! This is full-on

  • Ghostbusters stuff" "Oh yeah. Totally." "Where do I need

  • to stand?" "Uh, anywhere. I need help with a breaker,

  • that pin there, pull up."

  • (pin clicks) Destin: "Holy Moly! Okay." "Alright."

  • (Destin laughs)

  • Destin: "Where do I need to stand?" "Anywhere." "Oh, dude."

  • (Tesla coil buzzes)

  • "Wow."

  • (continued buzzing) Cameron: "That's super low,"

  • (buzzing stops) "but I can bring the intensity up."

  • Destin: "You know that that feeling when"

  • somebody has a loaded gun around you,

  • only the gun could point anywhere.

  • So I'm going to step back here. (laughs)

  • (deeper buzzing)

  • "Wow. So what's it arcing to? Why is it not

  • coming back to ground?

  • So, that's the primary coil.

  • No you do not have air-cooling on that!"

  • Cameron: "It's water cooled." "It's water cooled?!"

  • Destin: "You know what's unreal to me? I wanted to study Tesla coils, and I

  • started googling, and you live where I live."

  • "Yeah." "That's unreal." "It is." (Destin laughs) "Oh dude.

  • "One more time please." (buzzing and maniacal laughter)

  • ok ok, Let's get ready to do the

  • high-speed. let's do high speed."

  • (narrating) "After capturing several videos with the

  • Phantom, I decided I didn't like the

  • lighting. The problem was it was too dark

  • to see the gun, but I needed the darkness

  • to be able to see the arc. Cameron agreed

  • to bring the gun over my house the

  • following day at sundown, so that I could

  • use the sunlight to illuminate the gun,

  • and I used a black backdrop so I could

  • record the lightning bolt coming out of it

  • at 28,000 frames per second.

  • (buzzing)

  • Destin: "Got it. Got it!"

  • (whooshing background noise)

  • (crackling noise echoing)

  • (sudden buzzing)

  • (crackling continues)

  • (noises fade)

  • (sudden buzzing)

  • (echoed crackling)

  • (buzzing and continued crackling)

  • Ok. After watching this slow-mo, and seeing

  • that arc curve back towards Cameron, the

  • obvious next question to ask is: what

  • happens if you get hit?" "He's just

  • casually cleaning his Tesla coil."

  • (buzzing)

  • "WHAT?!"

  • "It's hittin' your hand!" (Cameron chuckles)

  • Destin: "What? Can that go through your heart?" "I mean yeah, but it's so low current."

  • The primary coil on a Tesla coil circuit? Fatal, no questions asked.

  • But on the secondary coil the

  • output is in microamps, which is

  • generally accepted to be safe, but some

  • people still say it's dangerous.

  • Here's the deal.

  • DO NOT do this. A lot of people say this

  • is safe a lot of people say it's dangerous,

  • I just really wanted to touch it.

  • "Ok, ready, ready to trigger the high-speed?"

  • "Ok, Oh God, I'm good, I'm good.

  • it just scared me

  • Okay, go ahead.

  • Okay. Wow, okay. All right. Yeah, it's thing."

  • (guitar music and crackling buzzing)

  • "So after I took that hit, Cameron asked me

  • if I wanted to shoot it myself. I don't know

  • if that was a rite of passage or what,

  • but, um, yes, I would like to throw

  • lightning bolts from my fingertips!"

  • "You turnin' my breaker on? Oh! good grief!

  • This Is like a video game!"

  • Destin: "I can't thank you enough for lettin' me do this.

  • I mean, this is like... the little boy in me is just..."

  • "Wow!"

  • "Okay. I need to give you your gun back".

  • I had so much fun making this video

  • I mean I just wanted to learn about Tesla

  • coils and, all this happened; I'm very

  • excited about this video. Anyway if you

  • enjoyed this video, and you want to

  • support Smarter Every Day then support

  • the people that support Smarter Every Day!

  • there's Audrey from 1 Tesla; I'll

  • leave a link in the video description.

  • there's Cameron at Tesla Universe;

  • leave his link down there, and then the

  • sponsor is Audible.com.

  • Audible has audio books that you can get

  • download for free if you go to

  • audible.com/smarter. I do this every day.

  • I listen to audiobooks on my way back

  • and forth to work. Special treat today,

  • Mark Cipher is a guy that I talked to

  • through Cameron; he's a Tesla

  • historian. He wrote the definitive book

  • on Tesla's life.

  • It's called Wizard, the Life and Times of Nikola Tesla.

  • When I told him I was going

  • to talk about his book in this video, he

  • got so excited he filmed a little clip for me.

  • Hello, my name is Mark Cipher, and I'm the

  • author of Wizard: the Life and Times of

  • Nikola Tesla. When I first learned about

  • Tesla, he was a very obscure figure, but

  • now his name has resurfaced, and he has

  • become kind of pop science icon.

  • Find Wizard: The Life and Times of Nikola Tesla

  • at audible.com/smarter.

  • I'm really excited about that. Thank you

  • very much, Mark. And if you want to support Mark Cipher,

  • go get Wizard at audible.com/smarter.

  • that will support Mark and support

  • Smarter Every Day. You should be

  • listening to audiobooks anyway; it makes you smarter.

  • Anyway I'm Destin. I really hope you

  • enjoyed this half as much as I did.

  • I hope this video earned your subscription;

  • If not, no big deal. I'm Destin, you're gettin smarter every day.

  • Have a good one.

Hey it's me Destin, welcome back to Smarter Every Day.
