Tim gets his feet wet again, with more of his water based toys!
Instead of the drinking bird, we have a drinking dinosaur! This is a simple heat engine, and you can explore how it works here - en.wikipedia.org/wiki/Drinking_bird
A snow globe that has hair in it instead of snow, and a man with very little hair. Shake the globe and see how much hair you can deposit on his head! The toy is called 'Over the Hill & Losing It!'
A handy gadget to like your stamps. Of course this was for older stamps that had glue on the back. Nowadays stamps are self adhesive. So sadly our handy gadget is now redundant...
A glass spinning top with a conical shape and a coloured liquid inside. When you spin the top, the liquid rises up to the wider part of the top, due to the centrifugal force, and you can see that there is now no liquid at all at the bottom of the top.
A column of water inside a Perspex tube. Inside the tube there is a buoyant ball, which floats to the surface every time you invert the tube. Because there is such a small gap between the ball and the side of the tube, the ascent of the ball is very chaotic. There is an air bubble beneath the ball, which is unable to get past the small gap!
Finally a Japanese automaton. A fish bowl, sitting on top of a book with the title 'My Fish'. In fact the batteries and motor are all hidden inside the book! Switch it on and a rotating magnet inside the book causes a small magnet to rotate inside the bowl, and since this is tethered to a fish, the fish seems to be constantly swimming around.
