The Straw Turbine is one of the simplest rotating toys. You need a stiff straw, a needle, tape and a bit of copper wire. Cut a 2-cm piece from the stiff straw and poke a hole in its centre with a long needle. It should be through and a neat hole. Then wind the copper wire on the needle to make a small loop. Weave the other end of the wire in the centre hole of the spinner. The wire loop will act like a stopper. Then wind the wire once again on the needle to make another loop or stopper. Between the two wire loops will be the small wire axle on which the spinner will spin. The SPINNER is now ready.

Make a small hole in the long straw and weave the long copper through this hole. Tape the wire on the straw. Thus the Spinner will be attached to the Blowing Pipe. Ensure that the Spinner rotates freely on its axle. On the blowing through the plastic straw the small straw spinner will rotate very fast. You can also make a turbine with 4-blades This work was supported by IUCAA and Tata Trust.
