okay today I'm going to show you how to make a barometer first you will need a jar make sure it's a coffee jar or or a jar that's heavy enough daughter plastic jar glove sticky tape scissors Arab in permanent marker doesn't matter what size or color paypal and 30 centimeter all up and stop the first you'll get the lid of the jar and the glove side marker and blow to blow up there go down get the permanent mark on put rest of it little me and trace it after you trace it you will be cutting it out and it would look like that after you cut it out replace it on the lid stretch it out and if you need sticky tape get some sticky tape that's it on here then you'll get the rubber band as you can see here as I did earlier good place it then after you did that you'll get your strong an estimate where you cut it make sure I put the pointy then get your permanent marker again and color tip of the straw 20 side then you get the straw and sticky tape it to the top of the jar and you'll do it sticky tape more than once because it's really won't really stay do it at least three times depends how well you sticky tape is and you'll get the paper fold it in half like this place it like that Monica mark mark where if it stays as you can see it's there you'll get your wall up this is the one I've done earlier get your ruler and measure where you marked it and do it at least one to two centimeters I'm thought after you do that you don't um get hiding a bit low load and low and a lot higher than high you can see then you're right no normal time then we measure it see how to bit over um the normal it feels normal the wind pressure it down then if you go to any that forbidden or normal go lower but it's the week it there's hardly any wind go around there or would go up after that you would just to make sure if pass it out and the store comes off just get one little piece hey stop here then we'll go me to a near a wall or outside place the jar where you want it to go and if you against the wall you don't have to do this both you're outside you hold it you try to hold it then or if you can balance you place it there or you can stick it over to the ground whatever you want to keep it up then the wind what pusher it down make it go up I'll leave Olivia's and I our goal was to was to measure the pressure of the year the first time we did it was a success because we use a plastic jar me realize that when the wind picked up it would knock the jar over and then in conclusion we got a new jar replace the outside in the wind with and we placed it in the house and outside it went a bit down to normal and inside it just move like slightly down um thank you for watching since a person I post this on my youtube channel um thank you for watching YouTube fans and thank you for watching out my class and the person who was recording this was Olivia and um thanks Olivia for recording this since too young since you made the first one anyone you want me to buy do it thank you for letting me do this one and then keep watching guys bye
