Conditions for Bubble – Spitting
– Condition 1: There is air in the pig's belly. If used multiple times, need to shake out the water in the pig's belly, just like shaking a mercury thermometer.
– Condition 2: Use freshly boiled water. If the water temperature is not enough, the air in the pig's belly and the external water pressure can't form a strong pressure difference, and it can't spit bubbles.
