Multicolor elephant toothpaste reaction

A spectacular outdoor experiment where several buried containers are filled with colorful reactants to create giant eruptions of elephant toothpaste. As the reaction begins, vivid streams of foam in red, blue, yellow, and green burst upward from the ground, rising higher than a person and merging into a rainbow-like cascade. The dynamic display of expanding, multicolored foam transforms the landscape into a living artwork of chemistry in motion.
