My Mars Medical Project is an Anti Cavity Contraption aka the ACC. The purpose of the ACC is to prevent cavities in the mouth area. The material the ACC is composed of is named Ninjaflex. The object that I have created also retracts back into the base to reduce the volume that this object takes up.To work the Anti Cavity Contraption, you must first put toothpaste on the bristles. Second, insert the object into the mouth. This part is crucial! It will not work if the second step is not completed! Lastly, rub over teeth vigorously and make sure the paste is covering all teeth. If used correctly, the ACC should prevent mouth cavities.
