ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.
*****************************************************************************
With did this as an experiment in our Citizen Science area... using real teeth!
We submerged teeth in flasks containing a variety of substances (water, cola, OJ and coffee) and asked visitors to compare the effects.
Teeth were attached clear string and could be raised up above the level of the fluid for observation.
To increase the gross factor, we included magnifying glasses so the staining and decay could be observed up close.
Sourcing teeth: We called one of the dental professors at a local university.
You can also try your local dentist.
