DIY Electroscope - Indy Labs #25 (At Home DIY Science)

[@fxirytrail]

Videos like these helps out students struggling with their projects.. Thankyou so much for posting this.

[@hazarikajoibobhandar7173]

Thanks a lot. You helped my daughter to do her project.

[@MrLundScience]

Hey, no problem. That kind of thing is EXACTLY why I made these videos! So cool that you were able to use them! I'll admit, they haven't been that popular, but I'm not deterred by that. It's for the few who find a good use for them, that's why I make them. That, and I love doing them. Thank you very much for taking the time to give me that quick feedback. It is very much appreciated!

MrLundScience what else can I use instead of this rod. Something that can be carried to school.

[@MrLundScience]

If your concern is with something being perceived as dangerous, I may have an option for you. As long as it's conductive, you can swap out the rod for other materials. One option could be to make a much smaller rod that sticks out of the lid at the top and the bottom, but not as much as to be seen as dangerous. At the bottom end, make it a hook, but then, make it a chain of metal paperclips that hangs down. You could also glue the rod in place with a hot glue gun. If it doesn't seem to be able to easily come out, it may be seen as less dangerous. Also, you can bend the top end of the rod sideways so it doesn't seem as pointy, and still put the aluminum foil ball at its end. The aluminum doesn't need to be pointed in an upwards position for this to still work. Did that help?

[@ivangrgic8537]

Thank you. You helped me for my school project

[@MrLundScience]

Awesome! It's school projects, among other things, that I made these Indy Labs for. Glad it helped!

[@joelfelosopo5130]

Does the size of the aluminum foil matters?

[@Peachy_Artz]

I have a question.. When you said we can do any kind of rubber plastic stuff could you give an example?

[@MrLundScience]

High density polyethylene.

[@KrisPierson]

Getting ready to do this with my kids. They’ve asked good questions about inductive charging since they got some small robotic toys for Xmas that use that tech. Question: the ball of foil - density, packing, size ...are these factors to explore?

[@MrLundScience]

Sweet! The next Indy Labs will have some further static induction happening, so your kids will likely not want to miss that one. Should be out in one or two weeks...but we'll see. It's Science Olympiad season in full swing, so I am absolutely swamped. As for the ball of foil, it's only there to increase the surface area that gets exposed to the charged object. Changing any variable that lessons the surface area will cause you to need to get the charged object closer to the aluminum foil. More surface area is better. If you are increasing the density of the aluminum foil by crumpling it up tighter, that would reduce the surface area, and you'll likely have slightly less dramatic results (but still results, none the less). So, as a fan of testing out variables, I'd say yes, it is an area that could be explored, but spoiler alert: It's not likely to produce better results. But it would still help them understand the principles better, I imagine.

What type of paper did you use?

[@SamudraFlavorsYT]

normal paper or paper we use to write on

[@alexstrouse6333]

Could you do a video on lumens and how to Measure them? And you would think if the air is dry that electricity wouldn’t work as well over wet air.

[@MrLundScience]

Hey now, that's a great idea! May I ask, what brought lumens up for you? Why is it that you wish to measure how much light something puts out? I'll look into this for sure. Just know, there's many videos already shot that will be edited and out first, so give me time, but I'll see what I can do! Thanks Alex.

[@alexstrouse6333]

MrLundScience Well what brought it up was a guy on youtube said his homemade flashlight gives out 36,000 lumens but he was using 9v batteries and 9v batteries can’t give out that much power and people were calling him out on it that he was wrong. Then i was seeing so many different answers to how much lumens he was actually putting out and i want to really have a accurate reading of how many lumens a flashlight is putting out instead of sticking to peoples word.

[@MrLundScience]

It's on my list of things for Indy Labs to do some research on. I've passed it on to the R&D department. We'll see what can be turned up and delved into. Thanks for the suggestion!

[@alexstrouse6333]

Thank you! can't wait for the video.

[@kylelindberg7771]

@@MrLundScience 3 years later... I guess you gave up on that idea?

[@MrLoserTree]

Amazing video!

[@votebakri]

Can I use aluminium wire ?

[@MrLundScience]

Pretty sure that you can. Some, in fact, do this experiment not with the pencil lead covered paper, but with aluminum foil pieces. I just find that they change shape or rip a little too easy. Point being, though, that aluminum is conductive enough that you should be able to get equal or very similar effects.

[@VideoStudiowithWalter]

Nice..

[@MrLundScience]

Merci!

[@robeldebe1279]

And can i use different wires

[@TSulemanW]

Nicely, use gold more better than aluminium

[@mjgamingzone730]

Can i use simple copper wire

[@khristinebahnweg5145]

Fun!

[@MrLundScience]

Hey, thanks! I hope you try it out. Great for kids and adults alike!

[@bluesapphire6184]

Cant move the aluminum, i dont know why🤧

[@robeldebe1279]

Thanks it helped i am gona share your video to my freinds

[@endashawendashaw5328]

why did u put the paper clip please

[@joelfelosopo5130]

Does it really work because I tried it and it is not working?

[@shooshe8211]

Why do I have to use plastic for the lid and use a glass container?

[@MrLundScience]

You do not have to use only those materials. Other materials are options. What is important is that the materials chosen are electrical insulators.

[@wheezz]

Will a Snapple bottle work it’s plastic

[@sohan8587]

Hlo it is osssum

[@Gio-du2bl]

Mine doesnt work.. why is that??

[@baladityaverma5033]

Mr Lund: American: Wow good name Indian Bangladesh and Nepali:💀

[@refill9737]

This doesn't work

[@MrLundScience]

I'm sorry that you didn't have success with this, but being a science teacher who has done this as a demonstration for 14+ years, I promise, it does indeed work if set up is done correctly.

[@refill9737]

Ye mb i realised the mistake I did and fixed it
