Science - Should I drink Soda

We are having so much fun with our anatomy study.  We are not doing all of the experiments listed but we are doing some of them.  This one was tons of fun.  We looked at how soda effects tooth enamel.

The basic experiment suggested placing a hard boiled egg in cola to see what happens since the shell of an egg is very similar to the enamel on our teeth.  We went farther. We wanted to see specifically what in the soda might be hurting the enamel, the sugar, the carbonation or the carmel coloring.

We put one egg each in regular Coke, Diet coke, and seltzer. We watched them and tested them every few days over the course of two weeks.

 The final results were very surprising.  The cola colored the eggs as expected but the seltzer totally ate through the shell.  So the results showed Froggy that even without sugar or carmel coloring, carbonation is bad for your teeth.
