In grade school we did some experiments where we soaked pennies and rusty nails in soda. We would check on them each day and take notes on what we saw. The activity was designed to deter us from drinking soda, but the results were shiny pennies and cleaned up nails. It made me want to drink more soda to clean the gunk off of my teeth.
