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...

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.

Different types of soda and number of mentos.

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.

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.

The more CO2 there is in the soda the bigger the explosion (all) 

The more Mentos

My dad helped me think what to write and my mom helped me print the stuff out. I also used DeepSeek for some research.
