Soda explosions!
CYSF · 2025
Overview
I will test how high an explosion will be if we put mentos in different types of pop!!
Hypothesis
I think that when I test Coke it will explode 1 metre, then Sprite will explode 1.5 metres, and A&W Root Beer will explode 2 metres? I'm just guessing...
Research
A&W Root Beer sprays highest. Coca-Cola sprays 2nd. Sprite 3rd. 4mentos in 1 710ml coke bottle sprays highest and 3 mentos in a coke bottle sprays 2nd highest 2 mentos sprays lowest.
Variables
Different types of soda and number of mentos.
Procedure
So first I will put a rain jacket on, then put 1 mento in a Coke bottle and measure how high it exploded, then repeat the process for Sprite and A&W Root Beer. Then see which one made the highest explosion.
Observations
All brown coloured sodas spray higher than not brown. A&W Root Beer sprays lots of bubbles after explosion. Coca-cola reacts fastest to the mentos.
Conclusion
The more CO2 there is in the soda the bigger the explosion (all)
The more Mentos
