Halting the Briggs-Rauscher Oscillating Reaction
The Briggs-Rauscher reaction is demonstrated in three different ways. Catalase from a liver extract decomposes the hydrogen peroxide in an Briggs-Rauscher reaction, stopping the oscillations.

Formation of Carbon from Carbohydrate
Sulfuric acid has a very high affinity for water. It is shown to dehydrate a carbohydrate (sucrose) forming carbon. Sulfuric acid is reduced to sulfur dioxide, which bleaches a rose petal.
In a second experiment, the sulfur dioxide reduces purple permanganate to nearly colorless manganese(II).
