Popping candy is a kind of recreational food. The carbon dioxide contained in Popping candy will vaporize in the mouth when it is heated, and then generate a thrust force to make popping candy particles jump in the mouth.
The feature and selling point of popping candy is the crackling sound of candy particles with carbonated gas on the tongue. This product became popular as soon as it was launched, and became the favorite of children.
Someone has done experiments. They put popping rock candy into water and observed that there were continuous bubbles on its surface. It was these bubbles that made people feel "jumping". Of course, this may be just one reason. Next, another experiment was carried out: put a little of the unpigmented jumping sugar into the clarified lime water. After a while, it was found that the clarified lime water became turbid, while carbon dioxide could make the clarified lime water turbid. To sum up the above phenomena, it can be inferred that there is carbon dioxide in pop candy. When it meets water, the sugar outside will dissolve and the carbon dioxide inside will come out, creating a feeling of "jumping".
Pop rock candy is made by adding compressed carbon dioxide into the sugar. As the sugar outside melts and the carbon dioxide rushes out, it will "jump". Because the sugar does not jump in the hot place, it will jump in the water, and the same crackle will be heard when the sugar is crushed, and bubbles in the sugar will be seen under the lamp.
