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:

Zinc: http://www.youtube.com/watch?v=knc1lSupAwQ

Sulfuric acid: http://www.youtube.com/watch?v=okvvD3-DF9U

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.

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