Why do Smarties react when they are put in soda?

Answer 1

Soda makes smarties dissolve because the acid molecules gets to the sugar in the smarties, therefore, that much interaction and energy soon die down in the smarties and fade away (dissolve). It disolves because it is suger? I really do not know why! smaties are a soft compound and carbon in soda breaks the cels apart like acid. facts: soda makes the botom of your toungue sting but only for sec.

Answer 2

The soda will rapidly foam as if shaken.

It is not a chemical reaction, since Smarties are mostly sugar (dextrose) which the soda already has if it is not artificially sweetened.

The rough surface of the candy (as with Mentos) creates nucleation points for the super-saturated carbonation of the soda. The carbon dioxide gas comes out of solution more rapidly than it ordinarily would, until the partial pressure of CO2 in the drink is the same as in the surrounding air (the soda goes flat).
