Specific Question:
what is the effect of different sodas on the height in cm of the explosion?

Hypothesis:
It is hypothesized that Mt Dew will be the highest.

Variables That Need To Be Controlled:
Geyser tube, same brand of mentos, same size of soda and put the soda in the same place, also used the centimeters in all of it.

General Plan
An experiment was conducted to determine how different sodas react with Mentos. 20oz bottles of Sprite,Diet Coke, Coke,Orange soda, and Mountain dew were purchased. One package of original Mentos was purchased. The experiment was conducted outside the school on the sidewalk. First a bottle of Diet Coke will be set on the sidewalk. The top will be opened and one Mentos candy will be dropped in and the lid will be resealed quickly. The tester quickly backed a safe distance away and their arm was extended above their head. A second tester will be standing approximately 50 feet away to take a picture of the bottle at its highest point. This process was repeated twice with each type of soda. It was important to open the sodas carefully so none fizzed out too soon. It was important to have a flat surface so that the bottles did not tip over. Safety of the tester was ensured by stepping away after the Mentos was placed.

Potential Problems And Solutions
you need to clean the Geyser tube or else the mentos get stuck and you fail your experiment putting different mentos in each trial is hard because of the data the whole pack of mentos should be added for each soda for each trial

Safety Or Environmental Concerns:
there really isn't any safety the only one is, is that if you don't want to get soaked my soda then move out of the way fast but if you do then stay there.

Results
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Five different sodas were used to measure in centimeters the height of soda when it exploded after adding mentos. Diet Coke had the highest explosion, measuring 128 cm, 0 cm,and 235 cm.Sprite had explosions of 63 cm,136 cm and 0 cm. Coke had explosions of 45 cm,0 cm, and 136 cm. Mt. Dew had explosions of 46 cm,70cm,60cm. Orange soda had an explosion of 31 cm,0 cm,and 100 cm. Diet Coke had the highest mean explosion height of 121 cm. The rest of the mean results are: Sprite 66.3, Coke 60.3, Mt 58.7, Orange 43,7.

Discussion
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">The question that ran the experiment was what was the height of soda after putting in mentos. Yes the question was answered. The answer was that Diet Coke worked the best.Diet Coke went the highest, the evidence that was seen was that it starts to bubble and less than a minute explodes. Putting in a certain amount of mentos matter on how high it goes. It was hypothesized that the Mountian Dew would go higher than Diet Coke and the orange would not go that high. Orange soda was the 3rd soda to be the highest, Mountain Dew was the 4th and Coke was right behind Diet Coke. Diet Coke was the best on trial 3 that's when the experimenters put in 5 mentos and for trial 1 they put in 1 mentos and for trial 2 they tryed to put in 4 mentos but it failed, because the 4 mentos got stuck in the Geyser tube and only 2 went in. It was challenging to measure the height of the soda in cm. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">It was challenging because soda exploded everywhere and the experimenters didn’t know where it was exactly.The experimenters didn’t have a choice to change how the design of the soda bottles were. The technology that was used to conduct this experiment were a flip camera to videotape my observation, The experimenters also needed a geyser tube because the geyser tube would make it shoot up straight and faster and also it helped to ensure that all sodas were an equal measurement. A yardstick was also used for data collection, using the yardstick was pretty easy, because it helped the experimenters to measure the soda accurately. It would be beneficial for future experimenters to use these instruments as they proved to be sufficient for accuracy for this experimenter. Therefore it would be recommended to use these same equipment. Looking back at the flip camera footage it was great to see that the experimenters couldn't use any other tools. The knowledge gained through this experiment could possibly indicate that the ingredients of the sodas that were tested maybe worse or better for you because some fizzed more than others and that’s what it is doing to your belly. People who have medical issues may want to know what they are drinking and what it could possibly do to their belly.In conclusion medical professionals and scienctist may continue to research these inconclusions and possibly change the way that these beverages are made. It could very well change the way that these drinks are made if they are doing damage to future generations.
