Coke and mentos volcano?!
Answers:
All CARBONATED drinks have reaction with mentos(the one which is not waxy,smooth on its outer surface)
When the candies come into contact with the liquid, a reaction causes the formation of foam at a rapid rate.Diet Coke, in combination with the gelatin and gum arabic ingredients of the Mentos, all contribute to formation of the foam.
The structure of the Mentos is the most significant cause of the eruption due to nucleation. Myth-busters reported that when flavored Mentos with a smooth waxy coating were tested in carbonated drink there was hardly a reaction, whereas standard Mentos added to carbonated drink formed an energetic eruption, affirming the nucleation-site theory. According to Myth-busters, the surface of the mint Mentos is littered with many small holes, allowing CO2 bubbles to form very rapidly and in great quantity, in turn causing the jet of foam.
