When ever you mix Diet Coke with any amount of Mentos, it makes the soda sort of explode. Why does this reaction happen?

Mentos is not very dense and has air pockets in it. Soda has a low pH and is considered much more acidic than the mentos mint, which is basic enough such that it gets dissolved by your own saliva. When acids and bases mix, fizzing bubbling usually occurs. In this case, carbon dioxide builds up in a sealed 2 liter bottle of soda. The gas is building up and trying to escape, and with help of a little agitation, it ends up bursting through the top of the bottle.

I found it! Apparently it's because the dissolving candy disrupts the surface tension of the water in the soda (any soda, not just Diet Coke). This allows more bubbles to develop faster, and also provides a rough surface on which the bubbles form.

yes.your obesrvation is 100% correct.
It is due to the formation of carbondioxide
