The thermometer can be flung down quickly by using the strength of your wrist. If you can’t, you can put the thermometer in cold water to bring the mercury down quickly.
The most commonly used thermometer is the mercury thermometer, which needs to be shaken down before each use. However, many people feel that they can’t shake it down, but in fact, it requires skillful strength, that is, using the strength of the wrist to shake the mercury down, rather than using the strength of the whole arm.
Because some people’s strength is relatively small, feel unable to shake down the thermometer above the mercury, you can put the thermometer in cold water for a while, so that the mercury inside the thermometer can quickly go down.
Be careful not to throw the thermometer too hard, to avoid throwing the thermometer to the ground, thus polluting the environment. If the body temperature is up to 39°C or above, you need to consult a doctor immediately to avoid hyperthermia convulsions.
