1st Class went outside to demonstrate the exploding diet coke and mentos sweet experiment. It was like an oil geysher . How does it happen?
The Mentos serves as a little factory and launchpad for bubbles—supercharging the normal bubble-formation process in the Coke. The mint’s rough surface has thousands of tiny pores, ideal for lots of bubbles to form. As the bubbles grow they float up to the top of the Coke. The process keeps chugging along, creating more and more bubbles until it explodes out the top of the bottle in a foamy overflow.
