Salt water Lemon juice Soda water Try making batteries out of other things, like potatoes or fruits. Volta found that this wet stack of “dissimilar metals” created a small electric current, and this current could be drawn off through wires and used for experiments. How can you make electricity from simple objects around the house? How does the amount of salt in a solution affect the solution's ability to conduct energy? We use batteries in everything - from IPods to cars. In their experiment they tested baking soda, salt, vinegar, and lemon water, and they concluded that the salt solution is the best conductor of electrolytes. The water not only separates the salt molecules one from another, but also separates the chlorine and sodium from each other. The copper and zinc metals act as positive and negative battery terminals (cathodes and anodes). At this temperature, all of the water will evaporate leading to an open circuit condition.
