Mentos Lab

Question:
What combination and inputs (pop/candy) will make the pop shoot out the highest?
Lowest?

Knowledge Probe:
● When mentos combine with a carbonated drink there is a chemical reaction causing an explosion/fountain.
● Fruit mentos have a glossy finish while mint mentos do not.
● Diet coke works best because it has different ingredients than other sodas.
Hypothesis:
I think that diet coke and mint mentos will have the highest explosion/geyser. Materials:
1.
Diet coke
2.
Diet Mountain Dew
3.
Mountain Dew
4.
Diet Pepsi
5.
Vernors
6.
Mint mentos
7.
Fruit mentos
8.
Skittles
9.
M&M’s Procedures:
1.
Place four mentos into tube
2.
Place note card over tube and make sure you flip tube over
3.
Open pop and make sure you carefully align tube with the pop
4.
Make sure you carefully slide the card from the tube and drop the mentos inside
5.
Repeat these steps however many times you want depending on if you’re changing the combination of either soda or candy. Variables:
Independent variables­ Combination of inputs dependent variable­ Height and fountain
Controlled­ amount of candy, placement, pop amount, wind (hopefully), temperature.

Conclusion/explanation:
Claim­
Highest fountain­ Fruit mentos/Diet Coke
Lowest fountain­ M&M’s/Mountain Dew Evidence­ diet coke and fruit mentos were 2.1 meters tall and others were less and
M&M’s and mountain dew had no reaction and others were all taller. Scientific Reasoning­
a. Not a fair test­ not enough…
