Make a Copper sulfate and zinc battery - "Gravity" design

video Make a Copper sulfate and zinc battery - "Gravity" design
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: http://www.youtube.com/watch?v=arlYPz3EP7A

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"

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

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.
