Sudden boiling chain science popularization time:

When we brew coffee and boil water again, the pot looks like a static heating process (pictured below).

But we start to put the upper pot into the lower pot (connected to the sudden boiling chain), and we will see a lot of small bubbles spinning around the beads (pictured below).

The size of these bubbles is actually the reference point at which we are judging the temperature of the water. The chemical explanation is that these beads form nuclear points, causing water vapor to begin to accumulate. If there is no sudden boiling chain, because the glass material of the lower pot is smooth and complete, it is not easy for us to detect when the water temperature is getting higher and higher. if we directly insert the upper pot into the lower pot and shake the hot water, there will be a sudden boiling phenomenon. The water in the lower pot will burst up, causing danger. So we usually insert the upper pot and the sudden boiling chain into the next pot of water before the water boils to prevent it from boiling.
