Well today using a plastic bottle we are going to make a simple and delightful spinner. Here you can see the boy playing joyfully with the spinner. To make this bottle spinner you will need a throwaway plastic bottle, scissors, needle and decorative color tapes. Let's make a hole in the bottle with the needle about 10 centimeters from the base. Then cut the bottle all along using a small scissors. This way you will get a plastic cup. The propeller will be made from this plastic cup. Now you can mark 10 equally spaced lines. And then cut these 10 equally spaced lines on the lower end of the bottle. Start from the rim and go right up to the base. Now once you have cut all these 10 petals, flatten them, open them and flatten them. It will become like a flower with 10 petals. Well you can decorate this fan using colorful tapes, stick various colors of tapes on these petals. And finally you will have to twist each petal to give them a curvature and make them into actual fan blades. Now the propeller is almost ready. If the bottle base is convex, then it is easier for the propeller to spin. Place the convex part of the propeller on the cut bottle mouth and place a hole assembly under a sealing fan. Soon the propeller will be spinning fast. Now the beauty of this dynamic toy is that it is made from a throwaway plastic bottle. And such a toy can be made accessible to the poorest child on earth.
