Seeing as there is so much talk about the weather here in the UK I figured I use all that weathertalk and do something productive with it. I've got a bunch of weather realated projects lined up for us to do. Today we made a barometer we took pictures as we went along.
Here's what you need
-1 long necked bottle-
-cd pen or label to mark the water level
Make sure the bottle and jar fit wel together
Fill the jar with enough water so it just touches the opening of the bottle
add food colouring to the water. Don't ask why I had pink I don't know, it was pink or yellow, and the yellow wellwould have caused a lot of potty talk lol!
put the bottle back into the jar
Stick the two together with tape and mark the water level with a cd pen or stick a label on the side and mark the water level on there.
Now just check the jar and mark the water level as and when it changes
