Can you die from eating Mentos and drinking Coca-cola at the same time?

No, this is an urban myth. It’s true that putting Mentos into a bottle of Coca‑Cola will cause an impressive fountain of soda to erupt from the bottle. In fact, carbonated water, sparkling wine and other soft drinks will have similar effects. However, you won’t get the same effect from eating Mentos after drinking Coca‑Cola. The eruption you get when you mix Mentos and Coca‑Cola is caused by the rough coating of the candy, which results in lots of bubbles forming rapidly on the surface when it’s placed in a carbonated beverage. But the coating begins to dissolve the moment you eat it. So you won’t get the same reaction in your stomach.
