Divya Raja Mrs.Vinklarek Pre-ap Biology 8 December 2014 title introduction The theory of coke and mentos has been around for a long time, its usually known for its reach of high heights. Many theories has been made about this experiment like the dimples on the mentos which causes the soda to explode. Which is actually true. The dimples provide a place for the carbon dioxide to latch on and undergo a physical reaction. The little dimples on the mentos are also called nucleation site. Soda is primarily composed of sugar, flavoring, fructose, and preservatives. The substance that makes soda bubbly is invisible carbon dioxide which is pumped into the bottle using tons of pressure. The purpose of this lab was to find out weather the 5 different …show more content…
It started to fiz more. Sierra Mist 5.32 seconds It exploded but at the end, it started to overflow for a little while longer. Sprite 4.36 seconds Schweppes 6.78 seconds It took the longest of all to die down. …show more content…
I stated that dropping four mentos in each bottle of soda than the geyser of the regular coke would react the longest. As you can see above in the data table and the graph the coke was fourth in place with the time of 4.56 seconds. It shows that the schweppes took the lead of the longest time for the geyser to die down after 6.78 seconds. The lowest time was 4.36 seconds for the sprite to stop reacting. I would of thought that the sierra mist would of stood in last place because it mainly consist of water but proving that it didn't, it was the third fastest as the geyer died down at 5.32 seconds. Diet coke turned out to be the seconded fastest at the time of 5.86 seconds. In my opinion I was concerned that my results were inaccurate probably being that I didn't drop the mentos in at the same time as I did the others. discussion In this experiment I didn't have any major problems doing this lab but this wasn't what the plans were. The original plan was to create dry ice and and figure out whether or not the dry ice will work efficiently in hot water or cold water. I was suppose to make dry ice by taking a fire extinguisher and shooting it into a pillow case. Results showed that yellow sand came out and not dry ice. I realized that we had to have a specific extinguisher, the CO2, and there wasn't any other way to make or find dry ice. The only thing I was left to do was to start a new lab.
