Did you know you can make a strong bridge from eggshells? Walk on raw eggs like Housing a Forest. Make a model mouth using biscuits, marshmallows, jam and peanut butter. This disgusting activity is one of 60 Gross Science Experiments you can find in my latest book, GROSS SCIENCE. Or, how about trying one of my other very eggy experiments!!

Test the acid levels in your favorite drinks with pH test strips, then soak shark teeth or eggshells in each drink to see if the acid weakens tooth enamel. Try it! Can the acid in drinks really weaken your teeth? Watch on. You Will Need.

The bacteria in the plaque produce acids (represented by the lemon juice and vinegar in this experiment) that can eat away at your tooth enamel. As your enamel weakens, bacteria can eat into your tooth, forming the dreaded cavities. Without proper treatment for cavities, tooth decay can continue and destroy your tooth.
