I would store coke in a cold place if I were to do that experiment xD
Diet Coke
Refrigerated cooling is far better. The reason being is that if you want a 'real' cool on a hot day evaporative cannot provide this. Once the temperature rising over 30 then evaporatives performance is serverely let down. On the other hand refrigerated pro vides you with a total reduction in temperature and provides you with better comfort
mentos really work better
mentos
Bkng soda vinegar is a CHEMICAL reaction, a chemical change occurs giving CO2 and water. The rate depends on the conc. of your vinegar, temperature and the surface area of the soda (fine powder)Mentos/coke is a PHYSICAL reaction, no chemical change occurs (though sugar dissolves and eventually hydrolyses to glucose, but this is incidental). The same thing happens with Mentos and carbonated water.CO2 dissolved in the coke is released by a process called nucleation on the surface of the mentos.A rough surface is better than a smooth one, so this might be a useful area to investigate for your project.The mentos reaction is probably fastest under most conditions, and you can experiment with temperature, acid strength, different types of Mentos (some are smooth and are rubbish), fizzy drinks with different amounts of sugar dissolved, lots of variables are there if you think about it.
Refrigerated tap water may taste better than non-refrigerated tap water because the colder temperature can enhance the perception of freshness and cleanliness. Additionally, refrigeration can help mask any unpleasant odors or tastes that may be present in non-refrigerated tap water.
Because the chemicals in diet coke react with the chemicals in the mentos, Normal coke has the same chemicals that mentos has, that is why you need to have a positive and negative to react, Normal coke and mentos is positive and positive.
You get a 2 litres of coke (Diet Coke works the best) and leave the cap off in an large, open area and put three~four of mentos (mint ones are better than fruit flavoured ones) in and then it will make a coke geyser.

they both work
Because heat contributes to accelerated and better protein (or enzyme) activity.
Yes, they definitely are.
