Diet Coke+Mentos = An Awesome Chemical Reaction!
Enjoy the show! There are many gret videos of the Coke + Mentos reaction on this site. Careful, though... they're homemade, so be sure to preview them before you show your classes!
Mentos and mint lifesavers have a compound in them called gum arabic, which chemically makes it easier for bubbles to form, by reducing the surface tension.
If you have a liquid that is supersaturated with gas (like soda, which is pumped full of carbon dioxide), a nucleation site is a place where the gas is able to form bubbles. Nucleation sites can be scratches on a surface or specks of dust - anywhere that you have a high surface area in a very small volume. That's where bubbles can form. Mentos seem to be loaded with nucleation sites.

Matter: States of Matter
Did you know the ancient Greeks first identified the three states of matter? Read about how the molecules differ in solids, liquids, gases, and plasma. View photographs and watch how the molecules move in each state. If you're really interested, read about a recently discovered fifth state of matter!
