Do you have a barometer in your preps?
Finding out the weather forecast these days is as easy as turning on the TV or checking your phone. That wasn’t always the case, though. In the hundreds of years before television and even radio, people used more rudimentary devices to predict what the skies would bring in the coming days.
One of those tools was the barometer. Once common in aircraft, ships, and ordinary households across the world, it predicts approaching weather by measuring changes in air pressure.
