Voltaic Cell Battery Kit
Make your own battery with this voltaic cell kit! This voltaic cell kit is a good springboard for your own science fair project on battery power. You will learn how chemical energy is converted to electrical energy as you experiment with vinegar, lemon juice and other electrolytes. This voltaic cell battery kit includes a clear plastic battery jar, copper and zinc electrodes, all hardware needed, and instructions. You supply vinegar or other electrolytes you'd like to try.
You can also purchase optional aluminum, iron, or carbon electrodes to make a battery with different electrode combinations. You can measure the voltage and amperage produced in your voltaic cell experiments using a digital multimeter.
These questions might help you come up with a good science fair project:
- What household electrolytes (liquid for conducting electricity that you put in the jar--like vinegar or salt water) are most effective for producing electricity?
- What electrode combination is most effective for producing electricity?
- How well does a carbon rod work as a positive electrode?

Great experimentReviewed By: Heather Gerber I ordered this for my ~8 year old son's science fair project. It is very cool, but not without a few challenges. First the pluses:
*electrodes are long lasting
*my sons is testing various electrolytes and comparing the amount of current they generate, this device makes it easy for him to be consistent in his set-up (always the same size electrode, easy to fill the cup to same level each time, etc.)
*has a "real" scientific 'feel' and look to it, which my son is thrilled about
challenges:
*the clamps that hold the electrodes are a little tricky to deal with. It is easy to accidentally loosen the nuts and let the electrode fall into the solution. Not a huge deal, but a little annoying
*I have had to attach the electrodes each time he uses it because of the clamp issue. It is difficult to get the electrodes at a proper height and get them clamped tightly.
*while it comes with a wonderfully detailed booklet describing voltaic cell experiments, including the chemistry behind them, it doesn't have a 'basic set-up' guide (i.e., how to tighten/loosen the clamps, the proper way to seat the electrodes in the clamps, etc.). Again, not a HUGE deal, but definitely has made it tougher for my son to be self-sufficient in his experimentation.
Overall, I would recommend this--just be prepared to fiddle with it a little to get it right.
