Why do people get so worked up over Michael presenting some of the videos? We all come here just to see Keith after all xD

jk Brady, we all love you too ^_^
Brady found a way to not be on camera in Objectivity. This was inevitable, but glad the videos are still being made. I really love this channel.
thatsoliz fear not - Brady will return! - James
I love it when Brady and Michael collaborate on a video. Two of my favorite RUclipsrs in the same video? Amazing!
Vincent Killion Michael's a top man and a great friend to us....

It was such a brilliant idea to start this channel, Brady. Science meets history in one of the most rewarding places for such an endeavor.
This video truly sparked my interest. Though I was quite shocked to find that Brady is "taking time off" by...doing more work, it does strike me as rather odd. I may need to recharge after so many puns. No, really, I deserve to be grounded.
E Hernandez Some of these puns were so bad you deserve the capital pun-ishement
Jacob Raymond I think you need to lightening up

I'm sorry, that was awful
E Hernandez With a capacitance for so many puns, how could you resistance?
More Brady Haran Michael Stevens collaborations please! :)
I love the look on Keith's face when Brady (or in this case Michael) make silly puns.
I really enjoy all of the channels Brady does, but this one really sort of provides the icing on the cake. On the other channels we hear about the research which has been done and the scientists who did the experiments, but with Objectivity you get to see the actual things the experiments were carried out with, or the actual notes written by the giants of science as they reasoned out how the world works. As an American, I never really knew much about the Royal Society until these videos, and now it's absolutely a place I want to visit before I die. I imagine I would feel a lot like a Christian might when visiting Jerusalem, or a Muslim in Mecca; sort of a 'holy land' of science. Thanks so much to Brady and James for making these videos, to Keith for his vast knowledge of the artifacts under his care, and to the Society in general for opening your doors and vaults to share these incredible pieces of scientific history.
How wonderful to hear (and see) the details of the experiment from Franklin's pen directly!
LOL 1:40 He 'conducts' this experiment indoors. Good one.
David Galvin Haha I get it. It's like a composer conducting an orchestra and Ben Franklin was a big fan of music. Very clever you are.
"No I'm not."
The results were quite shocking
I always disconnect my antenna cables before a storm. I often hear the _snap_ of electricity arcing inside the cable's plug, getting faster with the approaching storm. Each time there is a strike the arcing slows down, only to increase again until the next bolt.
RMoribayashi The antenna feed line is acting as a capacitor. The electrical activity associated with storm is charging in that capacitor until the voltage builds up to where it can jump the gap between the antenna conductors. That discharges the capacitor until the electrical activity charges it up again. naturally the rate of that cycling will vary as the storm approaches or moves away, as will a the storm changes in intensity
waswestkan That reminds me of a teacher I had who used to leave a well charged capacitor lying out for curious fingers.
"Well, it's certainly a very dangerous thing. Never, never try this at home."
Have a graduate student try it for you :P
Or just go next door
Oh well.. But people did know that conductors exist.. That electricity goes through some materials and not through others??
Was electricity being produced yet..? If not, then how did Ben Franklin know about the conductivity of the String and key...?
Plus, the Objecti-"V"-ty collabs are great... Keep 'em coming...
Aditya Khanna Yes, electricity was known and frequently studied in home laboratories at the time. They were aware that certain metals (e.g. copper) conducted electricity particularly well, and had just begun to work out, in rough detail, some of the laws describing electricity and magnetism. The Leyden jar Michael mentions had been invented about four years prior to this experiment. The earliest serious study of electricity and magnetism was conducted nearly 150 years earlier by William Gilbert, who coined the New Latin term "electricus" (from which the English word "electricity" is derived).
Wait a second, all Franklin showed was that a wet string will gather static electricity. If this same exact experiment had been done without any lightning around, as long as the string was wet, the same results would have occured. If lightning actually hit the kite, no matter how wet the string was, it would have disintegrated immediately and the guy holding it would have gotten a shock, depending on how much of the lightning would go down the string, since it's a terrible conductor to begin with. The fact that he can get static from the key to his finger means that it wasn't from the lightning at all.
***** Thanks for the advice, so I went and did some more research and looks like I'm not really wrong. You're basically dealing with a van de graaff generator. The effects described are because of the triboelectric effect, and it causes something known as electrostatic kite line discharges.
Normally this isn't a problem for most people flying kites to worry about because the string is an excellent insulator, but if you use a silk string, you're just collecting static electricity from the air, and extracting it from the other end. On a humid day, there's a static potential of 10,000v per METER, so a 100ft string can have a potential of 300,000v on it.
The reason that people got killed attempting his experiment is because their kites actually got hit by lightning. Ben's was just in the air collecting static electricity.
I have absolutely nothing against Mr. Franklin, I just watched this new video, and it peeked my curiosity, so please feel free to point out where I'm incorrect on my assumptions.
Eugene S I am thinking the same thing. Static electricity kind of makes sense, lightning makes no sense as it would have destroyed the kite and possibly killed the guy holding the string if it continued along that path.
Frank Force Lightning *IS* a discharge of static electricity, so you're coming up with a false distinction... Lightning is just a larger charge of static electricity being released. Science *STILL* does not know exactly why the large charges build up in the water/ice particles before a lightning strike.
Dracolith1 Yes, but Franklin didn't use lightning is the point. The electric discharge came from a buildup of static electricity from the air on the string, not from the lightning bolt hitting the kite. The point is that we're taught that he discovered that lightning is also electricity because his kite was hit by lightning, but look again at what he actually says. He never actually talks about the lightning even once, he's just talking about taking a kite out on a windy day with a silk string, then you can collect static electricity from the AIR (not lightning).
Also, we do know what causes lightning, its just a collection of static electricity in a cloud caused by the movement of air, water, dust, and ice particles in the air. I'm not sure why you think we don't know what causes it because it's fairly well understood at this point.
The point is, watch the video again and notice that Franklin's only talking about a slow static discharge from the string, and NOT that his kite is being hit by lightning and bringing that lightning down to him to touch with his finger. At 2:40 -"And the filaments (static discharge), will be attracted by an approaching finger"- he's not talking about the lightning, but about the static built up in his string causing a steady discharge onto his finger. He never says ANYTHING whatsoever about lightning hitting his kite other then the fact that he does his experiment during "thunderous" weather, which just means windy and maybe thunder, he never says "thunder storm", or "lightning", or even "storm". Everybody ASSUMED that he was talking about lightning because of his later saying that lightning=electricity and because this experiment was based on his previous experiment describing how to make a lightning rod, but what he actually proved is that lightning is caused by a static discharge in the clouds/air, and that you can easily capture some of that static electricity. NOT that lightning=electricity because a bolt of lightning hit his kite, the electricity ran down the string, and he got shocked. It's the rest of the world that assumed that's what he meant, even though he never actually even stated it. (At least not in the paper shown in this video).
Eugene S Lightning did not need to strike Franklin's kite for his experiment to confirm his hypothesis that lightning was electricity, but it could have ---- you have no proof that it didn't. "cloud caused by the movement of air, water, dust, and ice particles in the air." We don't actually know that, scientists are still studying the matter and attempting to figure out why that is; what you gave is not the consensus among scientists. It is just one of the possible explanations that has been proposed, and that short statement is oversimplistic and doesn't account for how the charges build up in the first place.
You should've said "These findings are SHOCKING!"
1:40 "Franklin says he conducts this experiment...." I see what you did there.
Interesting. Of course, everyone has heard of Franklin and his kite, but I don't think many people are aware of the scientific breakthrough it was.
Thank you for helping me with homework through an entertaining video 😁📚
The "Philadelphia Experiment"? That rings a bell...
Lol... This is the only pun made so far that has actually made me chuckle
Mike Thompson The trick is that it wasn't meant a as a pun. It really reminded me of this: en.wikipedia.org/wiki/Philadelphia_Experiment
I had the exact same thought! xD
Best channel ever!!!
I was hoping to see the key.
Eyy!! Michael!
'lynden' jar. Making a note here: Huge Success!
i love these informative videos. and Micheal make awesome videos as well. MORE!! I NEED MORE!! LOL ^_^
3:22 Leyden Jar perhaps?
This is really an awesome channel
Awesome
Michael sounded much less scripted this time, but Brady still just seems so much more natural.
Has anyone re-attempted the experiment??
On the positive side, my trust in you, Mr. Stevens, has strengthened.
Why is the museum guy touching the paper with ungloved hands? Isn't the point to keep finger oils away from objects so that they don't degrade?
Leyden jar.
A Leyden jar stores electricity, it doesn't make it.
i demand "Moar" objectivity! dose the British Royal society have any documents on pre columbian america, canida, central america, or south america? documents of the native codex from the miya inca or aztect??. or even viking accounts of exploration before the rest of europe?
Whatever happened to that kite? Where is it now?
Well Michael ,
Lyndon-Jar or Leiden-Jar, that is the Freudian question...
the thumbnail looks like a bug baked into a cookie.
Dunno what's up with these guys I personally love Michael's appearance everytime even though Brady's doing a fantastic job as well!
Like for Micheal and Brady! :D
I am a little bit confused. Did Franklin only observe these effects after the kite was struck?
Amazing Intro, and I'm not even being sarcastic
did he touch the paper with the gloves?
I’d have gone for shocking over electrifying
Awesome video :-)
Guests on objectivity is an awesome idea! Get destin! And Dirok from verstoblihgvff
We need a pun every single episode

yOu sEe iT rIgHt
I was such a dumb kid flying a key on my kite but thank God I never was able to fly it during a storm lol
Beny Franklin did not invent experiments either, but stupidly copied them from books ... which he bought from a touring magician in his city
Leyden jar
Day of the Tentacle : )
Why does Keith need no gloves?
Qermaq the gloves are more of a joke rather then needed
Qermaq It is meant to be a joke.
Why is it in the RS? Shouldn't it be in the Smithsonian Institute?
historian must discrediting him he did not invented electricity
Erp -- he's no Brady... :-)
His pun was shokingly predictable, couldn't he have come up with a more enlightning alternative?
shocking
Does anyone know (or have any idea) how did Franklin come up with the experiment?? What was he thinking when he came up it it???
No views... never seen that before.
That too on Brady's video... That does feel odd...
(***Heavily breathes in & out***) I am so surprised they didn't make a pun about Ben Franklin...that is frankly(!) quite disappointing...
Ooh.. I have never seen the "no views before"
(Yup.. Probably, first comment...)
If I wanted to see Vsauce, I would have subscribed to Vsauce.
Ksynix Q You seem a little grumpy :D
Ksynix Q he is a little bit less Vsaucy in these, but still..
Ksynix Q Lucky for you, this is not Vsauce. This is objectivity, a channel that I think Brady Haran is in charge of, and thusly can do whatever he pleases with. Bringing on Michael Stevens is, in my opinion, perfectly within his power.
Simon WoodburyForget What's your definition of nerdy and geeky?
Simon WoodburyForget brandy?
Was Benjamin Franklin a fello of the royal socity, I severly doute he was.
Abyssaljam He was a fellow, he was elected in 1753.
aa thanks
Abyssaljam Why the fuck would you doubt one of the most well know scientists of the day was a fellow of the royal society?
UlyssesKrunk because he's a ninja
FFS, Mr. Haran. I enjoy several of your vlogs. Is it so much to ask for a journalist to not lie nor manipulate?
I really dislike Michael, his interest in things will never look like more than an exaggerated and superficial front.
Why does England have this document!!! This should be in AMERICA, where all the greatest history of the world is at! I can't believe Obama would allow this to happen!!
Well, Ben Franklin WAS a member of Britain's Royal Society IIRC, so it makes some sense. Still, it is unfortunate that's not on display in some Pennsylvania museum.
i wonder how much of this is scripted
sooooooooDark none of our videos are scripted - we just roll the camera and go for it! Besides, when the objects are this awesome there's always lots to talk about.. Of course my most important job is to ensure that ALL puns make it through to the final edit - good or bad. - James
Just noticed this-- Sorry for the necro! Is Dr. Grime a contributing collaborator of non-numberphile channels still?
Go away vsauce, i didn't subscribe to your channel for a reason
iddn Because Vsauce is too edgy and smart and mind opening for you?
You are really missing out not subbing to Vsauce, he covers A LOT of ideas in each video. You aren't just learning 1 thing when you watch one of his videos.
Vsauce is one of the best science channels on RUclips. SciShow Mental Floss Vsauce2 Vsauce3 SmarterEveryDay Veritasium MinutePhysics MinuteEarth Numberphile CrashCourse
Thank you all for your great contributions.
Oh sorry, thy royal pain in the arse, King of RUclips! Didn't know all channels had to get approvals for the self employed surfs decisions to do collabs with their pals.
I'm sure if you had friends with an all most 10 000 000 subscriber fan base, you would throw them in a vid or two too.
USA USA USA
vsauce sucks.
Whatever happened to that kite? Where is it now?
I would imagine the kite got fried, LOL.
