The Bottle Turbine is an amazing toy designed by Durga a school girl. All you need to do is to mount a freely moving turbine on a bottle lid. There is a white straw fixed in the middle of the lid for the air to come out. The card sheet turbine is mounted on a flexi wire. If you blow through the lid air will come and the turbine will spin smoothly. Now fix the lid to the bottle mouth. This will be the whole assembly. Stand the bottle upright and squeeze the bottle repeatedly. Air will be expelled from the white straw and it will spin the turbine. It is an enjoyable game.
Next you cut the base of the green bottle and repeatedly move it up-and-down in a larger bottle filled with water. As the green bottle moves down air would once again be expelled from the white straw thus spinning the turbine. It is a glorious toy. In the end you just need to release the green bottle. It will slowly sink down – expelling air from the white straw and turn the turbine!
