I have a science project to do and I need to know why so many bubbles flow when you mix coke (especially diet coke) with mint-flavored mentos. I want an answer thats both scientific and sort of simple. thx!

There is an episode in the first season of Numb3rs where they explain exactly how it works. Try renting it from your local Blockbusters.

The Mythbusters provided a number of factors. It must be diet soda. It is believed that the chemicals that provide the sweetness affect the reaction. The general roughness of the mint is beleived to seed the bubbling process.
The reason this happens is due to a chemical process called nucleation. Bubbles of carbon-dioxide nucleate shortly after the pressure is released from a container of carbonated liquid. Nucleation often occurs more easily at a pre-existing interface (heterogeneous nucleation), as happens on boiling french fries or on string used to make rock-candy. So-called mentos-eruption are a dramatic example.
The surface of mentos (not the colored ones) contain thousands of small indentations (nucleation sites). Each indentation allows CO2 to form and be released from the liquid. Because the number of indentations is high, CO2 is released in great quantity and all at once. Aspartame (the sweetener) also plays a role. The colored mentos have a glazing on the surface, which smooths out the indendations, thereby making nucleation difficult.
Regular seltzer or soda water doesn't work because the CO2 already wants to leave the solution and can easily do so. The sweetener in the diet coke holds the CO2 in solution better, which makes for a more violent reaction.
ii Just Googled it

it is not scientific but coke a cola is some bad *** stuff it will eat a penny in a matter of days and if you have battery acid corrosion on your car battery post then if you pour coke on them then it will clean them, so I'm sure that coke will be an acid like effect on most anything

its the carbonation in the soda that interacts with the ingredients of the candy,kinda the same way with alka-seltzer and water.
