It’s half term in the UK which means that GeekTechV2 and I have had chance to get outside and carry out some science fun. In this case, adding some Mentos to some Diet Coke.
We used 3 bottles (1.5 Litres per bottle) of Diet Coke to see the reaction. The reaction is physical and not chemical, as tiny bumps exist on the Mentos’ shell which as the Mentos falls through the Diet Coke help to break the carbon dioxide / water bonds in the Diet Coke making bubbles, which then want to escape from the bottle. If carrying out this experiment please do so in an open space and please clean up / recycle any waste.
