Wow. Sir u r still here!! I pove the way u teach. 11 yrs ago sir 🙂🙂🤗
I also just watched the 12 years old
why being apologetic about not wearing masks
If anyone has a sense of history and they look at the publication date, they will ask "Why did they hold this during the middle of a pandemic?" The obvious answer - that it was held before the pandemic - won't be obvious to some. So, you post the clarifying comment to avoid needing to do something like this...
The 2021 episode of everyone’s favourite yearly series!
Such an awesome teacher. Breaks things down so they’re easier to grasp, and understand.
true
This man is still going after 12 years, wow... You're amazing!
3:57 teacher: "plastic makes good-"
student: "plastic!"
They're not wrong.
What I learn :
-Negative meets Negative they don't stick
-Opposite charges stick
-Lightning is more hot that the surface of the sun
-It takes to second for a sound to travel 1 mile
-I failed basic science & math
-I need to go back to school
Lol
5 seconds for a mile
You are here after the 10 years later recommended video 💢
Maybe
How’d you know
Yes
Becuz ur too
He has became opd
Very expensive piece of scientific equipment
(Two pieces of plastic and a clip)
14:31
Teacher: "if it's negative and it's attracted to this what's this?"
Student: "positive"
Teacher: "how could this be positive?"
Student: "because it is"
"protons."
One atom says to another, "Hey! I have lost an electron." The second atom says, "Are you sure?" The first atom says, "Yes. I'm positive." (My apologies: old physics joke.)
"What's the largest thing around?"
-YOU!
"Uuhhh not me 🙄 what's the largest thing around?"
-THE EARTH!
"YES! I'm not larger than the planet thank you very much"
Wow that got me omg 🤣🤣🤣🤣
This guy explained it better in 15 minutes than my tech teacher did over the course of 9 months
(also that little "fly, be free, go!" with the packing peanuts was peak comedy)
The best session of physics teaching I ever attended. So impressed and happy!
Love watching your videos they’re so helpful in learning some pretty tricky concepts
such a refreshing style of lecture presentation
You are a awesome teacher.
We need more teachers like you😍😍😍
an
I love this hahahaha, I wish more teachers made explaining all concepts more entertaining!
Loved the way you teach
Love these lessons
Simply wonderful 🥰
Dude.. i love you! If everyone gets teacher like you, students interest in physics will be increased exponentially!
I'm 54 years old and I'm finally understanding electricity! I can't wait to see your other videos!
Great job, thank you for your hard work!!
The great and mighty, Steve!
Not to be TOO fanboyish, but your enthusiasm in teaching does Carl Sagan proud. 👍
Wow... i just saw your 10 year old video and came here to find this new video! Sir, please keep up the good work
10:41 "not space we all would be dead" :)
this man is gonna help me not fail electricity.
Oh my god great different from 12 years before and now but fun is always there 🧡🧡
My favorite teacher ever
This dude is sutch a good teacher tho.
well, My fav. online teacher is getting older. thank you Jefferson for making our study so easy🙂
Very good explanation 👏
You are a Great real teacher. Hope you are doing well.
So far, so good. Hope you're doing well as well.
11 years later and still teaching students. What a legend
Funny demostration
This dude is just AWESOME
Wow. This person uploaded a prequel to a 10 year old video today. (21 Hours ago when I'm viewing it)
“Swiggy delivery service has left the chat”
Worked for Star Wars... sort of.
@@JeffersonLab Lol, yes, yes it did 😂
I see a fan right here
I’m in 10th grade from india , all my portions make sense with such explanation. It’s genius ❤️
I watched you 10 years ago....here you are still very passionate.....#proudtobeateacher
Electricity and statically driven charges wonderful.
Amazing
At the end he is like: "Should a person touch it?"
But touched it several times before in the video.
yeah but he only touched it when the other dome was in contact with the first dome, so electrons from the main dome travelled to the earth thru the second dome and didnt affect him. if he wouldve just touched the dome directly he wouldve been electrocuted.
@@dripcat5940 He touches it directly here: ua-cam.com/video/ubZuSZYVBng/v-deo.html

teacher: plastics make good?
Student: plastics....
😆
I learned more in this one video than I did in a whole year of high school.
Thank you teacher
Nice to see this guy 11 years later
Timing it right is the key .
hats off to science sir❤
I'm Always Waiting:")
Wow this is a bit of an shocking experience lol
Plastics makes good "plastics (from behind)" 😂😂
I love the guy in the backround saying random stuff
thanks
#good_one👌🏻
Nice
4:01 Plastics make good...
Random genius: p l a s t i c
Alright ladies and gentlemen today we learned
*Plastic makes good......plastic*
"Fly! Be free! Go! 😂😂😂
14:33
+How'd this get to be positive?
-'Cause it is.
And we called that "The Science"
Lol i like how he is acting and making students paniiiikkk whenever he tries something new🤣
2:08 i also thought same when I heard charge accelerator
Nice video
Thanks!
This is how all science teachers should be.
Mr. Jefferson... Just a small indispansable question : Is all of that magical actions came out of a coincidence? 🤔
After some poking around on Google, I think his name is Steve Gagnon. He is just awesome!
"Plastics make good...PLASTICS"
The kid who said that is a genius
He's channeling his inner Mr. McGuire.
Hail Legend 🙌 🙌 🙌 🙌.. true hercules..
I need more videos like this one!

Teacher: "Plastics make good..."
One kid: "Plastics!"
Well... they aren't wrong...
Yo it's been 10 years woah
May be 12 years ago but this dude sure still knows his stuff
This isn't from 12 years ago (yet). This was early 2020.

How fast can a jet make it around the world?
GlobalFlyer landed at Salina at 19:50 UTC (13:50 CST) on 3 March 2005, having completed its circumnavigation in 2 days, 19 hours, 1 minute and 46 seconds. As of 2019, this is the fastest world trip in its class at a speed of 550.78 km/h.
The light takes roughly 130 ms to travel around the earth - that is seven and a half times round per second.
sir I have a question that why opposite charge attract and same charge repel each other???
teacher: plastics make good...
student:plastics
dying rn

"Two pieces of plastic 🤤"
sounded like Ryan Reynolds on DeadPool.
ahh yes, plastic makes good plastic
4:00
We've found that plastic is the best substitute for plastic.
OMG! It's two pieces of plastic! They really saved no expenses lol ☺
Today I learned that plastics make good plastics. And something about insulator.
Insulators make good insulators.
He should get best teacher award 🥇
Yes, student in the back. Plastic does make pretty good plastic!
"Plastic makes..?
*P L A S T I C*
They're not wrong...
@@JeffersonLab technically...
Yep. Sometimes, that'll all one has.
Hey Jeff , you got old man....!!!
Beats the alternative.
@@JeffersonLab LOL!!!!
Here before it gets recommended to everyone 10 years later
cewl stuff.
"if you could run at the speed of light you could run around the earth 7 times in a second."
Me: the catch is you'll be a cooked corndog.
What is this instructor’s name? He is a terrific
Electricity doesn't pick the easier way. Instead the least resistance draws the highest current. And the purpose of ground is to draw high current so the circuit breaker kicks in when the safety of conductive casing is compromised.
How come the plastic pieces still repelled each other after putting the nail between them? The nail is a conductor and so are you so how come they didn’t lose their negative charge when you did that? Was the current too slow to discharge the static electricity?
The nail is a conductor, but the plastic isn't. Touching the nail to the plastic doesn't allow for the bulk of the charge to move to ground. If a charge happens to be somewhere other than where the nail is touching, it's difficult for it to move through the plastic to get to the nail. So, the plastic remains charged, even when the nail is placed between them.
Damn video ended on the main cliffhanger, I wanted to see someone touch the dome with the belt in it.
There's a reason why the title includes "A Prequel to 'Should a Person Touch 200,000 Volts?'" The resolution to the cliffhanger already exists in an older video called... Should a Person Touch 200,000 Volts? Links are in the description, or right here: ua-cam.com/video/ubZuSZYVBng/v-deo.html
I wonder what if you would try this experiment out in space with the same tools?
In space? Like, in vacuum? Well, for starters, with the same tools, it would be a very quick presentation as the presenter would quickly die. And, the Van de Graaff wouldn't do nearly as much as it depends on the resistivity of the air to allow charges to collect on its dome.
Thanks for
The kid in the background " we don't know"
Thank you very much.
At 3:05 when you swipped on the plastic , did you become positively charged ?
4:30 if you are positively charged , why don't the plastic become neutral , once you have been connected to the plastic? Normally the plastic should have become neutrale , since the electron can come back to you through the nail ?
1) Probably a bit. His shoes insulate some, so he was probably slightly positively charged.
2) The charges on the plastic really can't move around all that well. The charges can't 'walk' along the plastic to get to the nail. You'll neutralize the parts of the plastic that are in direct contact with the nail, but the parts that are further away will retain their charge.
So, how does the microphone stay functioning while you're touching the VDG? I have a job where I do a science show and I have a talk box on me.
I assume it's because the microphone is behaving like a boat in the ocean. While a boat rises and falls with the tide, internally, though, nothing changes. So, if the microphone's ground is allowed to float, it doesn't matter if the surrounding 'ocean' is at a high tide or a low tide. Internally, a five volt drop is still a five volt drop.
@@JeffersonLab But in your previous video when you were touching the VDG while standing on the stool...why the electrons were getting stored in you but not passing through the microphone's ground connection..i mean shouldn't it behave as a ground connection in your body.
The microphone doesn't have a ground connection.
4:01 me in class (turn subtitles on)
School would have been great if it was like this
👌🏻
i want this guy to be my teacher
would that spark burn your finger if touched (as it is hotter than the suns surface)?
One spark? No. But, if you had a constant arc going for long enough, you'd start to run into trouble.
its been 10 years and NOW you show us the prequel?
Yeah. There were some issues with the original footage that prevented us from using it for this. And it's also kind of a pain to record these things (lots of permission slips/release forms that we don't typically need to deal with, etc...). So... yeah. 10 years. Still a better pace than what they did with Star Wars. We have less CGI, though. Maybe we'll add some background creatures if we ever release a Special Edition.
