Did you know humans have up to 32 teeth?

We even have lots of different types that do different jobs. For example, our canine teeth are for tearing meat whereas our molars are for grinding our food. Today we have set up on experiment linked to teeth hygiene. We have placed some hard boiled eggs in vinegar to observe what happens over a few days. The shell on the egg acts like the enamel on our teeth, both protect. We made some predictions about what will happen. What do you think? Some of us thought the shell will go soft, some thought the shell will dissolve and some thought it would crack.
