An egg works well for this experiment. Leave it in a jar of cola for an
hour, a day, or a week. We set up multiple jars to show different
variables. For one jar, pull the egg out of the cola as you go and use
toothpaste and a toothbrush to clean it. The message about brushing is
made very clear.

so we all know about the classic activity of shining up a penny using
soda (or pop or whatever you call it where you live). Unfortunately, as
a demonstration for how soda is not so good for your teeth, it kind of
contradicts itself--to young children, it demonstrates that soda makes
things shiny and clean! Even the explanation that the soda ate away part
of the penny is not going to overcome the image.
So...what's a good substitute? Something that will look pitted and
nasty? And is ideally white so it "looks like" a tooth? We tried to get
some real human teeth, but it seems that's not really legal. (Who
knew?!)
thanks as always my science geeky cyberfriends,
