If I could please get a picture or diagram of the final product of this project: https://www.sciencebuddies.org/science- ... p087.shtml. I have followed the steps provided in the instructions, but I think that a diagram or picture of what the final product is supposed to look like would clear a lot of confusion. THANKS!

Hello Annny,

I'm assuming that you'd like to see a picture of the completed apparatus for the project. After some searching I found a site with a few photographs of the paper towel salt bridge and pencil electrodes.

Also I found a video showing the same type of salt bridge. During the video the students demonstrate some modifications to the experiment as well.

I hope this helps and good luck with your project. Please post again if you have more questions.
