What did they write?(Coke)
• How often do you drink cola ?
• We can do a experiment to find out the carbon dioxide • content in different cola , like coca-cola , pepsi .....
• and therefore we can recommend a "healthier" one (or the one which have a bad taste ^^) to others .
• The problem we have to solve is how to test dissolved carbon dioxide ? distillation ? or others?
• Please discuss and share your idea ....^^
