To test a barometer, you can compare its readings with a known reference, such as a reliable weather station or another calibrated barometer. Alternatively, you can perform a simple water displacement test by measuring the height of a column of mercury or water and ensuring it corresponds to the atmospheric pressure. Additionally, you can check if the barometer responds appropriately to changes in altitude, as it should show a decrease in pressure when ascending and an increase when descending.
The mercury barometer was invented by Italian scientist Evangelista Torricelli in 1643. Torricelli's innovation allowed for accurate measurement of atmospheric pressure using mercury as the working fluid in a glass tube.
The humidity can vary depending on the location and weather conditions during a rainy day. Generally, humidity tends to be higher on rainy days, but it may not necessarily be at 100 percent. It's best to check a local weather report for specific humidity levels.
The ideal humidity level for painting is typically between 40% and 70%. Humidity levels outside this range can affect the drying time and adhesion of the paint. High humidity may cause paint to dry slowly and potentially lead to issues like mildew, while low humidity can result in rapid drying, making it difficult to achieve a smooth finish. Always check the paint manufacturer's guidelines for specific recommendations related to humidity.
If the barometer shows a steady drop in air pressure, it typically indicates that a storm system is approaching. Lower air pressure is associated with unsettled weather, including increased winds, precipitation, and potential storms. Therefore, tonight's weather is more likely to be stormy rather than calm.

I don't have real-time data on barometer readings. You can check your local weather forecast or a weather website for up-to-date information on barometric pressure readings for your area.
You can measure weather using a thermometer, a barometer and an anemometer or other tool of choice.
Hygrometer.
To reset a mercury barometer after travel, first ensure the barometer has settled to room temperature. Then, carefully check for any air bubbles in the mercury column and gently tap the barometer to release any trapped air. Finally, adjust the mercury column height to match the current atmospheric pressure by turning the adjustment screw if needed.
A barometer is a device that measures atmospheric pressure, which helps in forecasting weather changes. It is used to monitor air pressure changes to anticipate approaching storms and predict short-term weather patterns.

You can measure humidity in your backyard using a hygrometer, which is a device specifically designed to measure humidity levels in the air. Place the hygrometer in a shaded location, away from direct sunlight and sources of moisture, and check and record the reading regularly to track changes in humidity over time.
