How to Make Paper Circuits | STEM Activity

[@emilybrackett2840]

Perfect. I wrote it all down in notes, and I subscribed to "Science Buddies".

I feel a Rudolf the Red Nosed Reindeer project in my future. Thanks for this.

[@thatwoomykid]

My friend actually made one before

[@pattycarr8289]

Thanks!

[@meowchistisimoo]

TYSM! This helped me so much for the project for my school, i'll sub

This paper circuit is awesome

[@shelleydumire8135]

Great video thank you!

Can I use anything instead of coin cell battery

[@jananimccausland1114]

Very useful video - thank you so much for posting. Can the LEDs be any length or does it have to be a specific length? I don't know what to order for my school.

[@Science.Buddies]

5mm LEDs are the most common and they're what you see in this video - the 5mm refers to the diameter of the LED, not the length. 10mm or "jumbo" LEDs are also common and will work the same way.

@@Science.Buddies Thanks for posting. This is THE BESTTT!!!!!

[@TheBenjibd]

And we can make it with different colours . And it makes light . It make colorful . And beautiful colours. I will make some of the paper circuit.

Great, i have one question related to copper tape wire pls help me out, I M using 3mm copper tape but its not working properly. So my question is how much mm is sufficient for smooth flow of current while using copper Tape pls help me out. .

[@Science.Buddies]

Hi - the tape does not need to be very wide, 3mm should be fine. You need to make sure all parts of the circuit are in firm contact with each other and that the tape doesn't have an insulating layer or film on top, if it does you need to scrape that off.

hello sir, i tried this paper circuit for some diy project but my paper circuit not working i tried many times, i m not from science background, could u plz help me and guide me

[@Science.Buddies]

Hi - if you are a student doing a school science project, you can ask for help on our website: www.sciencebuddies.org/science-fair-projects/ask-an-expert-intro

Thank you for this video

Thanks

Yes

I encountered the multicolor light issue! I stumbled across this video while looking up something else and had no idea I was going to be so validated on this particular issue! My red and yellow lights would light up but not white, or blue, or green! But the lights all worked individually. I didn't know if I had dud lights or poor connection or not enough power or the wrong polarity or what! How do you combat this issue so you can have multi colored lights? I wanna make a thank you card for someone who invited us over to watch their fireworks. 🎆 🎇

[@Science.Buddies]

Hi - you could make two (or more) separate circuits in the same card with two different batteries, and keep lights with similar voltages on separate circuits.

Thank because i am in 5th grade

Thanks so much for ruining science class for me
