Teeth

Teaching Ben: "You have to brush your teeth or they will rot." So we end up with the egg/vinegar experiment! If you don't know what that is, you put a egg in a cup or jar, then you pour the vinegar over the egg till its covered. then you let it sit for a day or for like 6 hours, then take it out and feel it. "Thats what happens to your teeth if you don't brush them good." was the warning!!!
