Jake Taylor : And the flash was born

Angelo IV : that class seems fun... until they take the exam

IJN Yamato : Not gonna lie, when he put his right hand on it and went "boo!" I jumped out of my seat

Namjoonie's Expensive Girl : Why am I not dead? I ask myself the same question.

jacob mitchell : this guy is an awesome teacher! i already knew all this but the way he was teaching was very entertaining so I watched it anyway.

Zangetsu999999 : I wish I had a teacher like this guy.

Mystic Moose : if i had a teacher like this in high school i would probably have invented teleportation by now

bahaaldin hmeidan : Wish he had online classes

TheGreatSheikh : There's clearly something good about this guy since I watched the whole video without getting bored

Simba916k : The science teacher we all wish we had..

Playboiiamoud : Its funny because today i was in the front row and while he was doing this everyone said hey, its not on! and he said i know its not on 😂 crazy how he said the same thing 5 years later

RobbieFPV : That teacher is awesome. I knew everything in the video already but I still very much enjoyed watching it. +1

samsoulee : That's some good teaching !!!!!

nygeek64 : Wow this teacher is amazing..

aZa : awesome! i wish i had a teacher like him :)

Creole : most of the comments are about how they wish this guy was their teacher. i wish he was my teacher too

Nicolas Fernandez : I couldnt understand the reason why he is not dead

Lukemeister : Wow, this video really jolted me awake. I love his spark of creativity!

TheGentleUncle : How was the current so low? Isn't it like connecting a human load on a 200.000 V source? Wouldn't the current occur through Ohm's "law"?

Anony Mous : Truthfully I didn't learn anything until the end. I thought a lightning rod was supposed to provide something for the lightning to physically strike and follow all the way to ground without going through one's house and potentially electrocuting someone and/or starting a fire. I had no idea it diffused the charge in the immediate area to prevent a strike in the first place.

supaH : I finally have a reason to watch youtube videos over going to school.

connor nicholls : I would love him as my science teacher

Joseph De Mello : So I should have a lightning rod at my house?

Kushothe : 120V? We have twice that in Europe.

I'm Juxie : 200,000 volts? 200,000 subs? Awesome coincidence.

Nathan Brown : Now touch something that is 30 volts and 200,000 amps. Lol

TheCuriousEngineer : This is one great video. But I still have one doubt. V = IR is the equation we use everywhere right? The question is how 120V outlet can kill you but 200,000V can't? I know that 120V gives out high current while this VdG with 200k V gives out less current. But if the human body resistance is same for both cases then what is the factor which determines how much current comes out from the respective volts? 120/R is much less than 200k/R provided R is constant which is human body resistance.  In this video, there is 200k V terminal and other is ground terminal. The man connects these two and current passes through him yet nothing happens but if he does the same for 120 V outlet, that will instantly kill him. So again what is the factor which limits the current if not the body resistance? I try to relate this to water body. A lake full of water (voltage). If we tilt the lake, water flows and that's current. Now how much current flows will determine if a person will be flooded with water or be safe. But still cannot figure out how current is different if R is constant. Please help :)

SwafflesYT : He's really good at teaching this stuff.

Ten Craziest : one of the few good prices of content on youtube

Aaditya Acharya : I need a phy teacher like him!

Edward Deaney : Do people not understand voltage? You can't have a single point which has zero volts; voltage measures potential difference, which is a relative term not an absolute one. The reason he is 'at 200,000 volts' is just because his charge state is higher than the ground's by a certain amount, not because he is at a level. He could be have a PD of 200,000V from the ground, but if he touched something that had a PD of 100,000V from the ground, he would only have a PD of 100,000.

Surkee : This guy is amazing. Only teacher I've seen in my entire life that doesn't make me sleep. I always had problems with electricity chapter in 6th grade because our teacher would never explain us stuff. Now all that mystery I had is gone because I watched an 8 minute video. Amazing.

ryanhayn : If his body has a given resistance of say 10k ohms, then 200,000V / 10,000 ohms = 20 amps. 20 amps should kill him. What's limiting the current?

The Dapper Llama : Wow, this dude is a great teacher! I actually learned quite a bit.

Info Geek : awesome..wish India had such professors

Lelle _123 : I wish I had good teachers...

RaikouX : Glad this was in my Recommended

wardstone1 : What a great teacher..

Dadycoool : I participated in a Van de Graaff demonstration when I was 10 at a Science Camp. There were two of us up there: me and a girl. She was touching the generator and I was holding a fluorescent light. It was pretty cool, and when I looked at the girl, her hair was sticking up spectacularly. Much more entertaining than seeing this instructor's hair.

99 Peons : even though it's all justified scientifically, he's a pretty brave dude for doing all that lol I wouldn't

Rami : This is more funny than being educational

RoniusMaxed : I just found out how to shoot electrons from my finger tips

Guitarfollower22 : Why is this on my suggested list? Why did I watch it? I don't really care about the preceding questions, I enjoyed this video. Thank you YouTube

Michal Korejtko : what if u jump?

B.W.S.K. : Should a person touch 200000 volts? Depends on the person - I have a list of people who should...

NateDogg : He looks better with the hair up

MalePrivilegeIsAMyth ChangeMyMind : THIS is how you teach kids, not reading this off a book or having them read it off a sheet of paper.

Bayan Zabihiyan : so in case if someone doesn't know. Voltage is the potential or difference of strength of two sources. current is the amount of electricity. Imagine a river, voltage is the incline, current is the water, and resistance is the width. without voltage (incline), no current (water) will flow no matter the resistance. adding voltage increases the flow. now if you go under a water fall will a super high voltage ( elevation) but little water (current) you will survive. same if you have a lake (lots of current) but no incline (voltage you will live). with both you will die. voltage forces current through the resistance. I hope I made it clear for some people.

Thefarmhelp : Why are there 120 volts in us sockets? Here in Sweden (I think in all of Europe to) it is around 220-230 volts. More energy efficient!

Lerquian : i'm studying electrical engineering and this video helped me to understand better what voltage is (in real life, not just in concept)
