To make this Bottle Ballerina you will need an old plastic water bottle, cutter, wooden sticks, straw, glue and other odd materials. First cut the bottle with a cutter in almost two equal halves. Cut parallel strips on the base part. Cut around 16 such petals which can be bent outwards to make blades for a fan. With a hot needle poke a hole in the base of the bottle. Press fit a stick in this hole. Also apply some glue. Now bend these petals outside and then twist them like the blades of a fan. 
Cut similar vertical petals in the top part of the bottle. Make a hole in the lid and press fit a stiff straw as a bush / bearing. 
Now assemble the two parts. Stand the part with the bottle lid on a table. Place the other part with the fan blades on top. For this you will have to put the stick in the straw. This will complete the assembly. 
The top part is a rotor with blades and if you keep it under a fan it will start SPINNING. You will also find that the lower part also shakes and dances. 
Decorate the model with color tape. On placing under a FAN the top rotor spins very fast and smoothly. In America half a billion water bottles are chucked away every week. So this model would be mean good recycling.
When placed on a table the rotor spins fast and the lower portion also dances in unison.
You can also place a Ballerina on the central stick. Then this toy becomes a Spinning Bottle Ballerina. What fun! This work was supported by IUCAA and Tata Trust.
