video of Briggs-Rauscher oscillating reaction.

Have you ever seen a chemical reaction that makes a solution change color? Probably. But what about a solution that changes color and then changes back, not only once, but many times? Sounds pretty exotic! Whereas most chemical reactions only move in one direction from reactants (starting chemicals) to products, in these rare oscillating reactions, the reaction products appear and disappear for a number of cycles. Because the products are colored, the solution appears alternately blue, then… Read more
