Make a Copper Sulfate and Zinc Battery - "Gravity" Design





Introduction: Make a Copper Sulfate and Zinc Battery - "Gravity" Design

About: NurdRage is a dedicate group of science nerds trying to further amateur science with direct how-to instructions in video format. We saw what was already online and we thought "we could do better".....

We make the classic copper sulfate and zinc battery using the incredibly easy "gravity" battery design approach. Great for science fairs and similar projects this battery can be used to explore many basic concepts in batteries.

All the components can be gotten from our previous videos:

Copper sulfate:


Sulfuric acid:

More information on the chemistry can be googled under the term "daniell cell"

    I believe it's sold in hardware stores to deal with roots in pipes, in agriculture to kill plants and by aquarium and pond suppliers to kill algea.

    ive bought some recently from bunings hardware in aus under the gardening section (used for pH levels in some plants i think) so try a gardening shop or your local hardware

    Excellent scientific experiment, with an optimal explanation. Is it possible to use a semipermeable membrane? If yes, how could it be made?

    hey nurdrage you know about chemicals right? well can you tell me what i can do with copper chloride if you know please.thanks

    ignore this instructable and the image then, it only makes sense if you can watch the video.

    i went to a friends and watched it but i still dont know what i wanted to is it reading in millamps or amp?
