Now for the uncertain bit. When you add the Mentos, the arabic gum and the gelatin start to dissolve. The CO2 is attracted to the rough surface, which is a perfect nucleation site.

至於无法确定的部分是，当你加入曼陀珠时，阿拉伯胶和动物胶会开始溶解，二氧化碳会被曼陀珠粗糙不平的表面吸引，这种粗糙的表面最适合进行成核作用，因此上面会形成？

The products present two different morphologies. We studied the nucleus in the center of the tetrapods by TEM, SAED systematically and finally discuss its growth mechanism.
