 * DETERMING IF THE TEMPERATURE OF MENTOS AFFECTS THE HEIGHT OF THE GEYSER **

Jillian J. Cary academy

The purpose of this experiment was to see if the temperature of the Mentos affected the height of the geyser. It was hypothesized that the temperature of the Mentos would affect height of the geyser. The method to conducting this experiment was to incubate and freeze Mentos. Next, drop them into different kinds of soda. The final step was to see if the temperature of the Mentos affected the geyser height. The results of this experiment were incubated Mentos in Diet Coke: 3.25 cm; incubated Mentos in sprite 44 cm; Incubated Mentos in Orange Fanta 33 cm; frozen Mentos in Diet Coke 99 cm; frozen Mentos in Sprite 49 cm; frozen Mentos in orange Fanta 34 cm; Room temperature Mentos in Sprite 49 cm; room temperature Mentos in Orange Fanta 34 cm; room temperature Mentos in Diet Coke 3.25 cm. Two more experiments were conducted testing if soaking Mentos in different liquids and of different temperatures. The results in the second experiment were soaking Mentos in ammonia for 24 hours, the whole Mentos dissolved; soaking Mentos in lemon juice for 24 hours, the whole Mentos dissolved; soaking Mentos in vinegar for 24 hours, the whole Mentos dissolved; soaking Mentos in oil for 24 hours, none of the Mentos dissolved. The third experiment results were soaking Mentos in microwaved soda for 24 hours, the whole Mentos dissolved; soaking Mentos in frozen soda for 24 hours, the whole Mentos dissolved; soaking Mentos in room temperature soda for 24 hours, the whole Mentos dissolved.
 * ABSTRACT **

It was found out that sometimes the Mentos stuck to the Mentos dropper if the Mentos dropper was not cleaned out. Also sometimes the Diet Coke went really high and sometimes it only went 10 cm. In the Mentos dropper there were holes and the soda went through the holes. Future experiments could be adding different types of candy to soda and seeing if it makes a geyser. Another future experiment could be adding dry ice to soda and seeing if the geyser is higher than Mentos.
