In Ai Apartment No.4 Middle School, Lv Ziqiao did a coke experiment.

Coke with mentos becomes a fatal "boiling coke", but adding salt is acceptable. In fact, it is not the contents of mints that make cola spew out, but the structure on the surface of particles that makes the dissolved gas in cola form bubbles. You can try the following methods. First, find a tube slightly smaller than the bottle mouth of cola, put mentos or salt in the tube, block the tube mouth with a piece of hard paper below, put the tube above the bottle mouth, pull open the cardboard to let the sugar or salt in the tube slide into the cola quickly, and at the same time, insert a part of the tube into the bottle mouth, and cover the gap between the tube and the bottle mouth with your hand, so that the cola will be sprayed out of the tube.
