Below, you’ll learn how to make a simple weather barometer. 1) Set the glass jar on a straight, firm surface. 2) Cut the balloon so that you have a nice round part left, without the long end. 3) Stretch the balloon so it fits over the mouth of the jar nice and tight – the tighter the better. We do not want a loose, saggy cover.

2021年11月3日 · You can use a barometer to forecast weather, especially if you combine measurements with temperature and wind speed readings. Here are two easy ways to make a homemade barometer using simple materials.

A barometer is an instrument used to measure air pressure as it varies with distance either above or below sea level. Italian scientist Evangelista Torricelli invented the barometer in the year 1643. He studied the characteristics of mercury when placed in a vacuum and used that theory to develop the first barometer.

2024年4月14日 · In this project, we will make a balloon barometer, also known as an aneroid (air) barometer, using a glass bottle, a balloon, a wooden skewer and a measurement chart. It will help you understand air pressure in a fun and easy way.

When you observe a barometer, a drop in air pressure suggests that poor weather is approaching, while rising pressure indicates improving conditions. Monitoring pressure changes can provide you with a simple yet effective way to forecast the weather. Building Your Own Barometer
