The Thinking Bucket.

What do you think is happening inside the bucket?
Well, great Thinking Bucket!! Loved it. How do you make one?
We thought the whole process was through displacement. Fluid poured into funnel. Fluid enters vessel(bag) and causes displacement of water sitting in container. Water then flows out of small black pipe. Simple!



We think that there is a bag in the top container which holds the coloured fluid. this bag expands and pushed the clear water ou of the top contatiner into the jug.
