Static Electricity- Triboelectric series // Homemade Science with Bruce Yeany

[@sinterniels]

You are one of the few teachers who understand that teaching through experiments or using objects, is the best way

[@YeanyScience]

I've always found it was the best way for me to understand

[@brandonejem8620]

Once again you've return to teach me something amazing! I wish other people could see just how amazing your videos are!

[@orioni]

Dear Mr Yeany. Thank you for sharing all of your demonstrations. I thoroughly enjoy watching your experiments, even as a 34 year-old.

[@YeanyScience]

HI Stijn, glad to hear yo enjoyed them

[@jacksonsinger6503]

The fact that its Homemade science means i can repeat (some) of your experiments and its gonna be really cool!

[@adamoliver82]

Hi bruce, your videos are so great and your passion is very admirable. once my son is old enough, he's one year old, I can't wait to teach my son about science using ideas and experiments that you demonstrate. Thanks for all the good stuff.

[@YeanyScience]

Glad it will help

[@Guishan_Lingyou]

Thanks for making these wonderful videos! I look forward to teaching some of these lessons to my son once he gets a little older (he's one now). In the meanwhile, little gaps in my own knowledge (that I didn't realize were there) are getting filled in while I'm being entertained at the same time. You are a great teacher! (Other people have commented that you deserve more viewers, which is true, but nonetheless it is no small thing that many thousands of people are watching and learning from you!)

[@adamoliver82]

looks like me and you have something in common paul!

[@NathanSeeley]

I'm Definitely putting "Questions Are Essential" on my wall at home!!

[@Hirudin]

Great video, thanks a bunch for putting it together! I'm going to watch this one a few more times so that I can (hopefully) absorb the information.

[@energycrafts8206]

Hi Bruce, Very nice demonstrations. In your short video you have almost covered all of what a college text would cover, except for the math. I believe the science of electrostatics has been relatively dormant for far too long and there are great advances waiting to be had in the future. Electrostatics is a diamond in the rough in terms of technology. Someday our what we call "advanced" electric cars using brushless motors may be thrown in the primitive scrap heap for an advanced version of Ben Franklin's electrostatic motor. Ironic, in that it is also the very first motor ever invented over 200 years ago. According to Franklin, it was not feeble or impractical as one might think of electrostatic toy motors today. He said it was able to turn a meat loaded "spit." So there was some torque there. With a serious research directive who know how far we could go with today's knowledge of insulators and dielectrics. An electrostatic motor in principle can be superior to any other type as it can not only convert energy more efficiently, but can also be made both from usually cheap insulating materials rather than expensive metals and also the materials can be far lighter for the same horse power rating. It might even make gas engines obsolete too. The students today may be the very ones to make this advancement and who knows it might have been sparked by your classes and wonderful teaching skills.

If only I had such fun and interesting teachers when I was growing up...

[@PlanGIV]

Hey Bruce, Amazing demonstration once again. It's like... a kind of magic... ^^ Thumb up and best greets from France!

[@YeanyScience]

Hi PlanGIV, nice to hear from you again

[@vloggersvlog8386]

is ye dead

[@mcesmy]

Awsome and inspiring as usual. Please keep them coming!

[@cjprowe5]

We need more teachers like you

[@aaronmcdaniel5893]

Love your videos they give me a way to show my kid cool things

[@wolfkillerkobe]

MY HAND WAS IN BRUCE YEANY'S VIDEO! 2:09

[@YeanyScience]

Hi Adriel, hope you are enjoying your summer. Sorry there'wasn't more of you in it.

[@Protegit]

Questions ARE essential!

[@DrNaz]

I love your vids prof!!

[@YeanyScience]

thanks Dr. Naz

[@jostheise1789]

if we would have such a physics prof it would be awesome and it would be interesting and not just boring theorie...👍🏼

[@sciencetoymaker]

Wow, so many cool, kinetic demos and great explanations! Do you find that you have to anticipate the humidity of the air when planning some static electricity activities? In other words, do they work out better in winter, when the air is dry? Do you think your school's air conditioning mitigates humidity problems even in summer?

[@YeanyScience]

Hi Slater, with static demonstrations the dryer the better but I can't anticipate the weather and schedule accordingly. While the air conditioning may help, our school doesn't turn it on during during the summer when no one is in the building. I'm working on a few more videos on static electricity and set up a dehumidifier in the room a few hours before I start does the trick.

[@thanhheu4129]

Thank you for making these resourceful videos :D Please keep doing what you're doing, it's inspiring and help many including me in their understandings and experiments :D

[@teexplicofisica]

saludos de Argentina Bruce!

[@Eliphas_Leary]

Und Grüße aus Deutschland! :)

[@MinecraftRosarino]

Vamos otro argentino

[@chrisw3834]

Pretty cool, thank you for sharing. I have seen a power generator/battery charger using this technique.

[@michaelt.t.hansen]

Great video. Such enthusiasm.

[@sFeral]

What happens when you put a triboelectrically (both + and -) charged material between conductor plates, and then both of them sandwiched together ? Can't find this experiment anywhere so far

[@MinecraftRosarino]

Awesome vids, i wish i have you as my physics professor!

[@rachclan560]

Wer muss es auch gucken

Hello Bruce, thanks for your videos, really nice work. Could you tell where did you get the accetate strips? Are they commercially availabe for education purposes or do you cut them from something? Are the vynil strips actually vinyl chloride (=PVC) or something else? (this question is rather out of curiosity, I think it's somewhat easy to find flat PVC pieces anyway)

[@YeanyScience]

Some of the acetate and the vinyl strips were purchased through a science supply catalog, I also cut out my own from some sheets that I purchased at a hobby supply store. Yes the strips are vinyl chloride

[@YakovL]

I see. Could you point to the site of the hobby supply store? I've tried to find some at AliExpress but it seems that I use wrong keywords..

[@christigramling7199]

I found your youtube videos recently and love them! I am teaching an ICP high school class for the first time this year. I used your experiment here for static electricity and it was great. Do you have lab reports written for your experiments that include materials, procedure, questions, etc? I would be interested in a resource like that if it was offered.

[@YeanyScience]

Hello Christi, I work with 7th and 8th graders so the work I do is fairly simple. I used to have some higher order assignments for static electricity that I passed on to another teacher. I'll check to see if she still has it.

[@christigramling7199]

Thanks. I did write up my own static electricity lab. We are now in a unit on waves so we will be doing labs on characteristics of waves, sound, color & light. If you have any of you experiments written up I would be interested!

[@christigramling7199]

What you do can easily be adapted to a higher grade level. I would be interested in buying your labs and would think other teachers would too. There are places like teachers pay teacher that you could use. Thanks for the great videos!

[@victorbrazil6558]

You are awesome!

[@vladimirtayzhev4211]

Hi, thank You for this video, very easy to understand, and was very easy to repeat the experiments with my 7 year old son. I ask for a favor: is there any easy experiment to make at home to show my 7 year old son that electrons flow from negative to positive in a circuit with a battery source? Thanks a lot!

[@YeanyScience]

There are quite a few sources available, do a search for electricity experiments for children and you should find some

[@thestout-heartedtears9724]

Great video ! I have never seen this 9:25 !

[@vikramchary9778]

Sir please solve my doubt sir- which is how the insulator losses and gains the electrons when it is tightly bonded with the nucleus to become charge

[@mr.johnzussino6217]

Great video - thanks:)

[@wilsongarnett5015]

I love your videos

[@samashley7174]

so cool

[@EmceeIntricacy]

You're alright you are :)

[@mariazubair458]

Wowwww

[@bojanicgoran]

Very educative, but I need help by someone. I teacher of physics and my colleague , teacher of chemistry have to do project. My part is to simulate ionic bound with pin balls and to do electrolysis of NaCl. I tried with teflon tape, mean to coat pin ball with teflon tape, but no success. Very weak effect, with rubbing teflon with naylon and etc. Does anybody knows the best ball pair ?

[@ofeyofey]

What is the name for the cloth he uses? Sounds like he is saying 'urlon' @3:46

[@YeanyScience]

it is Orlon fabric

[@ofeyofey]

@@YeanyScience thanks for your reply Bruce and thanks for these videos they are fantastic. I try to replicate in my classes.

[@LFPaiser]

10:50 What's that piece of wood with gears?

[@YeanyScience]

It demonstrates a few gears, levers and pulleys. As you turn the knob on the big wheel the operations then waves both flags back and forth but at different rates. Here is a video of it. kzbin.info/www/bejne/fnW9oouvaLV8p9E

[@wilsongarnett5015]

Bruce

[@moonlightsonata3682]

love you video

[@impossiblephysix2633]

Isn't is possible that the electrons go to another position so that the materials attract each other

[@impossiblephysix2633]

I think it because the electrons themselves repel each other and there could be a certain distribution so that this could happen

[@YeanyScience]

I will show more on this in the next video on static electricity

[@ithacaphysicsbus]

It's pretty likely that you are the only person in the history of humankind who has ever levitated something with a flamingo.

[@YeanyScience]

Hi Erik, LOL, I also have a plastic owl, but he didn't work so well today so I left him out of the video. I thought it was a bit more interesting than the PVC pipe. On a separate note, I am interested in visiting Ithaca one of these days and will get back to you on that

[@ithacaphysicsbus]

Yes, we'd love to have you!

[@MrRyanroberson1]

thank goodness you have that aura of innocence.... or this video would be something else entirely.

[@JollyJoel]

LOL that thumbnail
