Because the carbon dioxide produced (coke is a carbonated beverage) fizzes up and explodes due to the surface area of the mentos. Remember all reactions, apart from nuclear reactions, occur on surfaces. For the same reason, vinegar and baking soda react likewise. There is very vigorous bubbling looking like an explosion due to the rapid evolution of carbon dioxide.
