The project found that Coke cracked and blackened the eggshell the most, while vinegar softened and cracked the shell. Lemon pulverized and destroyed the shell. Water alone had no effect, but water with sugar softened the shell. The goal is to identify damaging substances to avoid to keep teeth healthy.
