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:

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?

You can find copper sulfate in their "Chemicals & Metals" section...

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.
Oh yes - thanks for reminding me of that (long forgotten) L
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
