hi guys um this is my weather project I am making a barometer so the stuff I needed for this project is a piece of paper a marker pen a pencil or strong piece of tape a needle a balloon rubberband and a glass jar not a rhythm I need this straw and because it's glued to the blue and so if the balloon gets pushed down I'm pushing it down it goes higher push if it gets pushed out it go slower I've only measured it three times one two three starting point with number one then it goes to number two then I went to number three number three was just a few hours ago um but I knew first the first one with the starting point so would I believe this needle was here for it's good to get exact point I believe the needle there is a good day for that point so the reason why I needed the rubber bands hold bloonan and this this is been uh pretty fun actually pretty fun actually making this project I liked how we had the player grips and do it thank you guys
