How to Build Your Own Barometer! Easy project to track weather changes.

In this video I show how you can easily build a barometer out of items you may already have on hand around the house and start tracking air pressure changes that can help you predict the weather. The material list for this project is: Materials: -plastic cup, glass, or can -9" or 12" balloon -wooden skewer or straw -foam board or wood -scissors -glue and tape -pen A glass jar or metal can will work better than a plastic cup, but the rigid plastic cup I used for this project works fairly well. The balloon is cut and stretched over the top of the container, then a wooden skewer or straw is glued to the middle of the balloon. As air pressure changes, it will force the balloon membrane up and done, causing the pointer to shift up and down as well, and allowing you to track air pressure changes. For best results, build the barometer when the air pressure is near average, and not while a strong high pressure or low pressure is located overhead.
