The One Doctor
Diet Coke and Mentos eruption
The One Doctor is a Big Finish Productions audio drama based on the long-running British science fiction television series Doctor Who.
The Sixth Doctor and Mel come up against an impostor Doctor and his companion Sally-Anne.
A Diet Coke and Mentos eruption (or Diet Coke and Mentos geyser) is a reaction between a carbonated beverage and Mentos candies that causes the beverage to spray out of its container.
The numerous small pores on the candy's surface catalyze the release of carbon dioxide (CO2) gas from the soda, resulting in the rapid expulsion of copious quantities of foam. Although any carbonated beverage will produce a similar effect, the reaction was popularized using Diet Coke for seemingly producing the best results.

Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells in an effort to produce energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering, and agriculture. Today, most of the food energy consumed by the world population is supplied by the food industry.
