|How Not to Clean Pennies|
So we cleaned pennies again and then experimented with baking soda and vinegar and experimented with rinsing and not rinsing them (not rinsing leads to blue/green oxidation spots). While at Target, I found a workbook of science experiments in the dollar section and purchased it to give us some guidance. You can also find Kids Science Experiment Books on Amazon.com.

|Our "Lava Lamp"|
I like these types of experiments that use items I have in my house and are mostly inexpensive. For cheap baking soda for experiments, we replaced the baking soda containers in our refrigerator and saved the old baking soda for her experiments.
