Moving Particles with Vibration, Making the Chladni Plate 

Mehdi! Thank you for the shoutout! This was epic, and hilarious as usual. I can’t believe you even attempted to move the particles, that’s EXTRA. Btw, you stumbled on some really interesting physics at 5:25 that I may or may not have already been thinking about for a future video….

"Let's fast forward to the future to see how it worked." "FKK, IT'S NOT WORKING!" I love this channel.

Everytime he uploads im glad he didnt die

Wife gets home Wife: where is all our salt Electroboom: I have absolutely no idea

I love this man's artistic use of the F-word. His art form makes him seem not vulgar while cussing every two seconds. Also he has good science content.

Freaking cool man! This episode was so good, I think it deserves a standing wave. I'll let myself out

1:13 I think that is the calmest I have ever seen Electroboom XD

0:35 now that’s music.

"Let me increase the amplitude so the vibrations are more visible" True fans: *stiffen in excitement*

I'm from China. I got here using VPN. Many people do the same for "political sensitive" videos banned in China. But I'm here for watching a guy testing his resistance with live wires and showing graphs, formulas I once struggled with during my college days. I now work in IT industry so I don't touch sine waves and care about grounding anymore. But your videos always bring back my good old memories in the college labs where I sweated hard each time before I try to connect some wires to another or turn up a switch. Since the China-US trade war began I found it's becoming harder to get out. Many VPN and foreign IPs are being blocked more frequently than before. I have to switch VPN service every another week or so. But I think all these worth it.

Hi ElectroBOOM, the other day in engineering (before school ended haha), my teacher started talking about Kirchhoff vs. Faraday’s voltage systems and asked if anyone knew about it, and I had seen your video about it, so I raised my hand and said what I knew from your video, and my teacher was really impressed! So thanks! :)

9:56 “I’m a bit afraid of resonating glass” says the guy who sticks his finger in 120V sockets without any hesitation...

This is the content I subscribed for. Golden comedy

What I realized after watching this video is that the outro is just his unibrow forming a standing wave!

I'm a life-long engineer, and although I initially thought you were a bumbling dangerous goof, I now realize you are brilliant and very entertaining. Thank you.

0:36 I almost died laughing 😂🤣

10:00 "Seems like its making these crack lines" *Proceeds to rub nose*

"I'm seeing more viewers from my Chinese and Iranian views so the VPN is clearly working." LOL

11:57 I can see this becoming a method for separating granulated materials by density. You could take a small sample to know what materials are present, then tune it to separate the materials.

Everytime I watch an electroboom video I keep wondering if a *FULL BRIDGE RECTIFIER* will be used or not

He accidentally invented the Sonic Cocaine Line Maker! The Levitating Coke Line Maker is in development...

Wow, no capacitors were harmed in the making of this video. However, a speaker and a glass plate were most definitely harmed. 😂😂

Mehdi, I've found your channel as well as its content to be glorious, it takes nothing less than a genius to create content which is not only informative and entertaining, but also something as a viewer you want to see and inherently learn from it, personally I am a big fan of learning the ways something works through experiencing how it fails also, it gives me insight to recognize when something is not operating the way it should, because I've experienced the ways it doesn't or shouldn't work. I'm learning without even trying! If you ever read this comment, I want you to know that I am someone who's been struggling to learn about electricity for years and now, through your content, I am finally starting to understand it. I can finally call a truce with electricity and create a path to understand it. I appreciate your hard work.

Your videos are so much fun and so educational! As an older engineer still building lots of stuff, I still love watching your videos. You would be a wonderful professor at a university! And I never get tired of waiting anxiously for the high voltage discharge or burn shriek!

did you plug that speaker straight into the 120v outlet??? lmao!!!

0:36 *BZZZZZZRT* Mehdi: FUUUUUCK! Looks like ElectroBOOM is a speaker too!

Hello Mehdi. I have 2 suggestions for this: (1) Maybe it is possible to set the input wave generator with a variable phase shift. In this way, you will be able to change the phase shift and, in turn, move the position of the zero point of the wave. You can then change the phase shift manually (with a knob) or else use a ramp generator to control the phase shift linearly. (2) In your experiment, the salt was stuck moving left-right around a point maybe because the COMBINED WAVE was too fast and the salt could not follow. Imagine the combined wave being a sea wave and the salt being a person on a surf board. If the wave is slow enough for the guy to follow, then the guy would be able to ride the wave without problems and continue to move in one direction ... But if the wave is too fast, the surfboard would be slow and it would eventually end up on the peak of the wave and then on the other side of the wave, therefore moving backwards (down the trailing side of the wave) ... Following this reasoning, maybe your combined wave was trying to push the salt to the left, but then the wave was too fast and its peak went past the salt which means that now the salt was on the falling side of the wave which made the salt move to right until the next wave came to repeat the process. It would have been good to try to slow the COMBINED wave using F1=100Hz and F2=100.1Hz (rather than 101Hz) to make the combined wave travel much slower. Actually, it would be interesting if you make such a test for point 2 as a follow-up video : )

Your videos helped me 2 years ago with passing my exam in electronics... Now I study IT and once again you are helping to understand some aspects. Thanks mate!

How to break glass without damaging and also without cutting instruments 11:14

The best video I have seen in years. I became fascinated with the Chladni figures decades ago, and I'm still in love with them.

The speaker plugged into 120 volts AC was hilarious!!.😂👍

10:02 "Seems like it's making these crack lines, *sniff* *sniff* " So that's how he survives those shocks.

Nancy, the house speaker 🤣 You had me laughing in waves! That was hilarious, always make those references they are the best

Beautiful experiment MR. Thanx!!!

I have always loved your videos!!!

"We learn through disappointment" - ElectroBOOM, 2019 😄😄😄 This needs to be on a t-shirt.

I found you from a RU-vid compilation and I never cared about electricity until I found your channel, amazing fun to watch videos. Thank you for making these amazing videos!

I love you! This is such a cool chanel!!!! 😍😍😍😍And the information is so well explained ! I'm excited 😁made my day

A sound is absorbed when moving to a more dense mass and reflects when the mass is less. If you have a circular poster board with a more dense material like nylon plastic on it's out perimeter the sound generated will be absorbed into the the poster board then will enter the plastic then will reflect within the plastic reflecting back and forth within the plastic without reentering the poster board. Great video Mr Boom

Singlehandedly saving golden era of youtube. Thank you mr. @electroboom

" Let me just connect it to my subwoofer" * Russian hardbass intensifies *

Omg!! You won't believe how many times I wound back to watch that speaker light up! Just brilliant!!

Very interesting. Nice job of explaining

Hello sir.. You educate us with humor and exciting to learn more.... You are genius to do this kind of stuff... Moving of particle is awesome.. You always getting shock but not worrying about it.. Inbetween your puns makes me laugh... As always your video are interesting... Thank you sir....🙏👍😊

your wife: *where the fricc is our salt?????*

7:52 what you hear: 331hz what i hear: sound from avengers endgame theme

This was an nice Education video it helped me thanks!!

I've literally been binge watching all your videos 😂

2:21 OMG I spit my coffee on the computer xD Don't do that!!! hahahahahahahaha

Hey Mehdi! I really have no clue or knowledge about science stuff, but seeing your videos especially at 5:30 gives me interest in physics and other science stuff and not to mention it's inspiring!

Mehdi: "when you excite the magnet" Speaker: BRRRRRRRRRRRRR

I’ve been watching this channel long enough to know the second you brought out that pane of glass it would be broken by the end of the video

Your old persian subscriber here. Since you had 100k subscriber.

This is amazingly cool looking!

Thats awesome, the spots of salt inbetween standing waves that you showed reminds me of patterns i see with magnets with ferrofluid and ferrocell and also water vortices

"You learn through disappointment." - I died there. Priceless knowledge related in a funny way. Keep it up Mehdi. Awesome work.

11:11 "Let me increase the amplitude, so the vibrations are more visible..." *Glass breaks*

Nothing but awesome ! As always !

This is a wicked cool project, seeing physics in action is beautiful! If I was a high school physics teacher, I would definitely try to build this because it might make some kids interested in physics.

4:50 perfect way to make ur coke line :D edit: wtf 100+ likes lol ty guys finnaly someone thinks im funny😐

Honestly, I'm suprised that speaker even survived for a small second. 60Hz sounds great

As a music lover and making my own equipment... I realy enjoyed watching this movie clip... Nicely explained... In word and graphics.. .thank you for sharing and let people learn.. 👍❤️

You made me cry with such an amazing experiment. It really shows how wonderful can science be.

Sir I have been following your channel for a few years now and have watched all of your videos! I really like your videos ,they are very informative as well as show the dangers of using electronics and are ,of course, entertaining .I really have learnt a lot about electronics (pretty much everything) from your videos 👍 I really Hope to meet you someday as a fan and as an Electronic enthusiast . I live in India by the way so if you have any plans of visiting India I would definitely want to meet you. Thank you !

Yaaaaay! Fresh video from ElecroBOOM!

Awesome man. Your videos are highly addictive.

At the end of the video you showed an example of movement through the air. I could imagine this having some very useful applications in industrial automation. Moving particles without the need for conveyors/buckets/etc. You could also probably sort particles by tuning to certain resonant frequencies, and only the important ones float up.

Brilliant. I knew it was theoretically possible but ive never seen it done practically . Thank you .You mad nerd !

Do you have any baking sheets? That would be a large metal flat sheet that you could push harder than the glass panel. :)

very cool, all your videos are interesting! you've inspired me to learn electronics. so far i've built a power supply, a function generator, and a mini theremin.

awesome work continue making videos cool👍

Thanks again for the last coupon code you gave for circuit specialist, I was very glad to use your code as I know it helps you too

Mrs. ElectroBOOM be like "Dammit, where did all the salt go?"

Awsome video. Very Wells explained

Very Interesting experiment.. I do like what you do Brother.. 👌👌👌👍👍👍

0:36 - The ultimate earrape.

9:40 Interesting how the salt cloud changes between being a fine cloud and salt clumps

This guy explains ideas in the simplest way possible , keep it up mehdi, you're the best 💪

4:49 (That Scientific Cocaine Dealer!!!!!!)

I am an Electrical Engineering Student, I love watching your videos.

Informative and entertaining as always. I live for your uploads great content Mr. Boom👍👍👍

Even though you might mess up sometimes you still make your channel laugh and teach us something new, the best channel

Dude your amazing and entertaining Already sub you since 2 years from now

You should open a *_HUMOURINGENEERING UNIVERSITY_* !!!!!

Video out for minutes. Allready 110 veiws. Good job. You are Hilarious and very informative to us unknowing underlings

Im in high school and always had problem wid the concept of standing waves stationary waves u explained it soooo nicely

The effort Mehdi puts into saying Chladni, man if I put even 10% of it, I would top my batch...

Hi Mehdi, I think your 2 speaker setup failed because by gluing down the board at the edges (to the speakers) you fixed the medium's boundary conditions so that reflections are inevitable. If you wanted to try again, maybe glue them the same distance apart again, but use a full size foam board. You'd still get some reflections probably, but then you could try to impedance-match the foam board to the surrounding air by gluing on some wide paper fins along the rim. The waves should couple into the paper, then dissipate the energy into the air, making your whole setup a better approximation of an infinite medium. Then you shouldn't have to worry about reflections

I was expecting the glass to burst into flames! ElectroCUTE's piano playing is amazing! Has she stopped making RU-vid videos?

You remind me of my history teacher and shaping teacher in school many years ago, he could also make us listen because it was fun and educational.

It was really good video on Standing wave and it's application

7:47 when your plate oscillates whenever your wii crashes

8:31 Plate: *vibrates at 330Hz* Mehdi: *Plays music in E Minor* Noice.

By using a lot of ultrasonic transducers, like you mentioned at the end, you can also create certain points where the 40kHz gets modulated to around 200Hz by overlapping. You can actually feel those spots. So you can create haptic feedback by simulating shapes with those spots.

This is a great demonstration of beat frequencies/oscillators.

..................We get a stationary wave with nodes and antinodes, And *THAT'S* *WHY* This video is sponsored by *EXPRESS* *VPN* !!!!! Lmao!

Was waiting like forever for a new video... Huge love from INDIA ❤️

you know, ive watched every video on this channel at least like 3 times but I can't leave

The particle cloud coalescence and disintegration is amazing. Looks like there are some superior harmonics that are able to separate smaller particles and, at different amplitude, overcome electrostatic attraction between them.
