- This video demonstrates how to construct a working model of Alexander Graham Bell's first telephone. This phone was constructed in 1876 and supported Bell's successful patent application for the first telephone.
This seems deceptively simple. I always thought the principle behind the phone was magic.
LoL
is it possible to use ordinary drinking water? For telephone.
same here
@@putnik805 add salt to water and it will be more conductive or add hydrochloric acid not too much, but use it in open area because you will produce chlorine gas
@@putnik805 no because it wouldn’t have any conductivity
When I tried building this, I needed to add salt to the vinegar in order for it to work. Furthermore, the signal is so strong, I can hear the message very clearly!

@@putnik805 uhh, i dont know.
Hello kind sir. I am wondering if there could be interference with this device: The microphone picking up the sounds the speakers make which auto amplifies.. ?
Nice! I tried this! It’s 100% clear! Thank you for saving me for helping with communicating
@@putnik805 You should have an ionic solution in order for the current to be run through. Drinking water is a poor electrolyte since it contains little to no dissolved compounds. A table salt solution will work fine, but keep in mind that running current through it will cause it to release toxic chlorine and explosive hydrogen gas. In my opinion, the best choice would be a non-active metal sulfate, such as copper (II) sulfate. It won't release any toxic compounds in the air.
I'm in a rabbit hole now, really trying to educate myself on things we take for granted because we're born into an era that already has everything invented and perfected, not really needing to understand the principles behind them! This is soooo cool! As an African American woman in my 20s, I want to acquire and understand these everyday things. So grateful for this video and the eloquent, detailed, easy-to-understand set-up of it. Thank you for posting!
You isn’t a rabbit hole
@@MikeSalcedosGadgets lol wHAT?
In 2002 the American Congress recognized the Meucci's invention as "the first telephone".
Impressive! I work for a telephony company and never knew what the original design looked like
We must understand the primitiveness of all this. The light-bulb was not even available yet. Speakers and Microphones, and amplifiers were not available or thought of yet, and the record/recording machine was only being considered about this time. So in a way, Bell also invented the first speaker and microphone. It took quite some time about 50 years, till we have the coil/magnet speakers and microphones of today.
Was there even rubber for the diaphram? Or were they using leather or paper or something?

This is an important video because it discusses the pioneers original thoughts .. ty
Wonderful video and tutorial. I was clapping for you, when i heard the device work.
its amazing to see how pepole managed to make theese things shame that nobody really knows about the pepole who made it cause they deserve more credit
Sir you always rock, all of us learn a lot of Physics concepts from your excellent videos. In only 10 minutes duration video, you teach us all those excellent concepts, which our University Teachers can't teach us in a 4-years Bachelors Degree program. Sir may you always live happy, healthy, wealthy, respected life with your family and friends. We always love you Sir.
K. I made one. How do I install Angry Birds?
lmao
Hahahaha
Place some fake bread crumbs around the mouthpiece

I'm glad I found this historical and educational film on blackberry phone devices
Is is always a pleasure to watch your videos. Thank you!
With all our pre knowledge and advanced technology, this is obviously still difficult to pull off for the average person. You.even needed to use a tester which Graham Bell didnt have. And it's still a challenge.
*THIS PROVES ALEXANDER GRAHAM BELL WAS A GENIOUS!!!!!!!*
So true
Dude they were way beyond genius. It's hard to even imagine the level of creativity, faith and determination. Beyond way beyond genius. Smart smart smart people weren't even close to close as genius as these guys.
Well acually Meucci invented the Phone...
Please keeping adding awesome videos like this. Always great to watch them!
Thank you for posting this, I find this very interesting and cool!
Most amazing is, I think, is Mr. Bell's idea of convertining vibrations in a conducting liquid into an electric current. Thanks for th video.
The inventor of the telephone was invented by the German Johann Phillip Reis who built his telephone in 1859. The first sentence was (translated) “The horse doesn’t eat cucumber salad”. In 1861 he gave a new model of his invention the name “Telephon”.
Woah! That's so cool! I'm definitely going to try making one of these. Never would have thought the principle behind the first phone was so simple. I'm a bit curious how it would have sounded if, instead of a speaker, you used the electromagnet with the metal switch(is it like a relay? )
So?
Did you make one?
I have a book from 1888 called "the farm and household cyclopædia" in the book there's instructions for a telephone. Here they are
To Make a Cheap Telephone. Take a wooden tooth-powder box and make a hole of about the size of a half crown in the lid and the bottom. Take a disk of tinned iron, such as can be had from a preserved meat tin, and place it on the outside of the bottom of the box, and fix the cover on the other side of it. Then take a small bar-magnet, place on one end a small cotton or silk reel, and round the reel wind some iron wire, leaving the ends loose. Fix one end of the magnet near, as near as possible without touching, to the disk, and then one part of the telephone is complete. A similar arrangement is needed for the other end. With this one can converse at a distance of about 100 yards
Hello.. Do you have a model that you made before on your channel that can be viewed to try to identify it to learn how I can make one. Thank you..
This video is so helpful to understand how do phone works.
Brilliant demonstration. I want to try it. Can you you show us how to connect the battery to this model?
Bell managed to do this without amplified speakers.
Now, that was impressive.
Meucci was the true inventor NOT Bell.
Yeah, an impressive theft.
@@francescomastracchio945 Not Gray?
There needs to be an easter egg. There needs to be an easter egg in the interferences.
I made one! Thank you for the video, wherever you are. We will remember you.
And now we have cell phones gollly how far we've come thank you for sharing❤
Alexander Graham Bell was only credited for it. the real inventor is Antonio Meucci]
Another genius with a sidekick called Watson!
+Ahmar Saeed Maybe this Watson was the inspiration behind the literary one?
Vinay Seth Probably yes!
Thank you for the inspirational video! I learned and am inspired!
You could use this as a microphone.
I can just imagine that a person is online playing a game and uses this to talk, it would have to be amplified a lot though to make it understandable, but still proof of concept
I love all the things in this videos, including the music...gives you the feeling as you are about to make a discovery... (as it's actually gonna happen :-) )
is it possible to use ordinary drinking water? For telephone.
it is the night before the project about Bell's telephone is due, I just stated and this is everything I need to know, thanks!
I noticed a bit of interference in this video's audio and recognized it as a cell phone. As a guitar player, I've heard that many times when my phone was too close to the guitar pickups. I found it a bit ironic, since it's a video about the telephone.
that is amazingly cool. Enjoyed your video
thank u so much very grateful to you Can you please do a vdo on safety measures when working with electricity?
ANTONIO MEUCCI was The Original Inventor of the Telephone Alexander Bell was only 2 years old when when Meucci invented the telephone. Alexander bell was the first person to patent the telephone Meucci sued, and the court case drew considerable public sympathy for the poor Italian immigrant who could barely speak English. But the judge ruled in favour of Bell.
Okay this was a great video with one possible element of confusion. You mentioned that when the Wire W vibrates it creates a varying resistance. I would explain it a bit differently. The Wire W is cutting through the magnetic field of the circuit. Hence, it is causing a fluctuation of the current. Since a metal object moving through a magnetic field produces it's own current. The fluctuating current then goes on to produce sound through the receiver as you explained. I do not see how varying resistance came into this. You are not limiting the current. You are merely breaking the magnetic field with a metallic object. Please anyone, feel free to correct me if I am wrong here.
Great video. Thanks
Thank you for this amazing video. It was informative and inspirational at the same time..!! Slow clap..:)
great video thank you for this experiment.
And electric sound so I believe you can hear on the other. Side also two technical technologies Alexander Grand Bell
can you please tell me how a wire can carry actual human sound wave? I just can't get my head around how sound of a human can be transmitted through a wire.
Human voice, and all sounds, are waves of compressions of air molecules (vibrating at hundreds or thousands of times per second) that travel through the air. The diaphragm and wire are moved up and down from these air compressions. The wire just barely in the liquid and the battery form a "pressure valve" for electrons flowing through the wire. The wire moving in and out of the liquid is like a rapidly adjusted valve (a "variable resistor") controlling the number of electrons traveling though the wire (the "current"). When the wire dips further into the vinegar, this valve (the "resistance") is opened up so more electrons can flow. The pattern of elections flowing (the "current waveform") is now varying with the same pattern as the air waves are (the sounds). The speaker then turns this varying current back into sound waves by an electromagnet (whose strength of magnet force changes depending on how much current is flowing though it) that pushes and pulls a paper cone in the same wave pattern as the current (and the original sound) has, so the sound is reproduced at the speaker.
@@MrA2intl thank you Andrew for replying to my question. When I get home I will read your answer.
Would you mind if I ask follow up questions.
@@MrA2intl thank you very much. Your explaining how the sound wave is transmitted was actually what I wanted to understand. Very clearly expressed and thereby easy to understand.
Great project, I loved the presentation and explanation!
Excellent and very interesting video. Thanks for your work and posting!
Some say a Mr. Gray invented the telephone, and Bell looked at Mr. Gray's "caveat", which was basically a place holder one submits to the U.S. Patent Office, after which time one has a year to submit final patent application. Bell looked at Gray's caveat and then within a couple of weeks he changed his design and made his telephone work. It was known at the time this was happening and there were many court cases about it. Bell started dating a prominent politician and judge's daughter who also had ties and influence at the U.S. Patent Office. He listened to Bell's idea and set up an appointment for him to view Gray's caveat. The Patent clerk was a drunk, owed this man's friend money, and testified that Bell had given him a $100 bill to look at the caveat.
that was great! thanks for sharing! very interesting!
What specific ammount of voltage does it need for it to work?
And now phones are used for porn and iselfies.
+Martin Godinez What a time to be alive!
Martin ...and without two cups and a string! LOL :-) (double entendre there)
LOL true lmao
I loved this video. Wishing to try this asap.
very nice! thank you; ❤️❤️
Good work.
Wow! Way to go! Great job! :-)
I was learning the OSI / TCP IP model and i became curious about this invention.
The ADHD Mind is a curious one.
Thanks for This.
Phone ringing
Fud: Sorry wrong number
Holly: how’s it going honey
Fud: what are you doing now I thought it was the wrong number
Holly : i’m sorry but it’s not a wrong number so what are you cooking today?
Fud: i’m cooking fish rice casserole
Very intriguing stuff.
Im really interested to know how he even came to the idea that this was possible
I thought the 1st telephone is a string a can
Of course. But we're talking the first true accurate electric phone.
Thanks a lot for upload this video.
The photo shows what I believe was called the gallows transmitter. Drum head with a coil and metal piece in contact with it
Thank you for the excellent existing
Sir I have a doubt...the vessel which you poured vinegar it has to be a copper or any other material
nice lovely work he would be proud 📱📱📱📱
sir, one think but at that time how did they reproduced the sound here as u did by using a amplifier speakers. how did waston heard the voice??????
My Major question is why the wire W from brass rod to suspended membrane wire connected ? You haven't did the same in your experiment also. It might be a Wave W - Hope not Wire "W".
Please explain
What can be used instead of nichrome wire and a copper bowl that contains vinegar?
Very nice👍😍
You probably should have used a high voltage, usually sound systems of the early type were voltage driven, not current driven
Wow so cool !
Hi, they left me a job and I would like to build one, could you tell me the specific materials?
is it possible to use ordinary drinking water? For telephone.
From where do the speakers get current supply...???
I don't see why the water thing was necessary. I thought in microphones the coil and magnet combination just moves up and down in ways respective to the amplitude and frequency of the sound waves that hit the diaphragm that the coil connects to. Why water?
because its science..come on..
That wasn't water, it was vinegar which is about 4-8% acetic acid; an electrolyte solution that allows the flow of electricity. The motion of the metal rod causes a change in current flow, thus changing the amount of current reaching the receiving electromagnet (speakers). This causes the vibration of the magnets in the speakers to be in sync with the input sound waves, effectively transferring sound from one location to another via electricity.
Thanks
I tried to build the same phone, I used plastic paper and a 9.5 volt battery but I have no signal. please can you help me this is for a school project and it would be super interesting for me to build one that works.
Hi, did you manage to finish your project? I'm also trying to make one for the school fair. How did you manage to make yours work?
I really want to attempt this. Are there any tips from anyone whose done it previously?
thank you Sir ,i hope that you make another copy of classics invention
Whats the measurments of the wood
Great video! RIP sir.
Does anyone know what kind of receiver was used back then to repeat back what Bell told Mr. Watson?
Electromagnet with iron tin plate
Beautiful 😊
I always wondered how can I build amplitude modulation...
What kind of Mambrane did you use ..
Wonderful
Meucci era il vero inventore....... upload.wikimedia.org/wikipedia/commons/thumb/7/75/Antonio_Meucci.jpg/220px-Antonio_Meucci.jpg
Where can you buy nichrome wire?
i love your all video love you😘😘😘
Thanks, that is great.
How Alexander think about it???
Liquit mic is interesting device... use lake surface a large mic... ( put electrodes in lake and hear tought amplifier... ) need to try...
What was the power source?
Is the interference supposed to be a joke? :P 'cause you're talking about telephones lol Anyway nice video!

@@putnik805 It works with salt + water
Ok. I've heard of peanuts, but teanuts? The world is a strange place.
i was trying to make a wireless one!! is it possible?😅😅
in which sound wave is converted to mechanical wave then a reciever which convert electric wave to sound wave!!
also trying to make two way😅😅
pls help me!!
Omg 8 years ago!!!
Alex Graham Bell spoke into the telephone? What about the Italian who made a primitive aid for his wife. Surely that was the first telephone? Antonio Meucci.
how did they amplify the signal in the 1880's
Bell did not use the amplified speaker. It is an important difference.
It's just an analog microphone.
What is the name of the liquid?
I think u can just use table salt in water. As long as its a liquid that conducts electricity decently
@@pencilography2025
Oh i see.... Thanks
Amazing now send so.much so many
Because he was in the other room and actually heard him?? 😄😊
