可樂coke+mentos

It is the deit coke will make the highest ejection.
It is because the sudden rapid formation lots of bubbles. As one
drops Mentos to a 2-litre diet coke, the rough surface of the Mentos
providing the sites for generating bubbles. As the Mentos sink down
to the bottom, the bubbles increasing a lot. The carbon dioxide in
the coke also make the ease to form bubbles. The sweeten aspartame,
& gum arabic reduce the surface tension of the coke also help to form
& stablize the bubbles. With all conditions together bubbles burst out
in a very short time hence resulting a coke spray eruption.
