Video Overview

  1. Take a straight straw and cut it in half . Take one of the half straw and again cut it in half.
    • Take a straight straw and cut it in half .

    • Take one of the half straw and again cut it in half.

  2. Bend one of the small straw in half. Nip the corners of  bent straw. Nip the corners of  bent straw.
    • Bend one of the small straw in half.

    • Nip the corners of bent straw.

  3. Cut both the ends of the straw diagonally. You now have a straw having a diamond shaped center with diagonal cut ends. You now have a straw having a diamond shaped center with diagonal cut ends.
    • Cut both the ends of the straw diagonally.

    • You now have a straw having a diamond shaped center with diagonal cut ends.

  4. Take the other small straw and diagonally cut both the ends of the straw. Insert this straw in the diamond hole made in other small straw. The looks like fan of turbine model. Insert this straw in the diamond hole made in other small straw. The looks like fan of turbine model.
    • Take the other small straw and diagonally cut both the ends of the straw.

    • Insert this straw in the diamond hole made in other small straw. The looks like fan of turbine model.

  5. By using thin binding wire pierce hole on the other side of the diamond. Make hole on the other side by repeating the above step.
    • By using thin binding wire pierce hole on the other side of the diamond.

    • Make hole on the other side by repeating the above step.

  6. Take another small straw and using scissors make a hole at the center by piercing sharp end of scissor. Repeat the above step for the other side of the small straw. Now insert this straw  on the diamond hole created on the other straw and then insert thin binding wire .
    • Take another small straw and using scissors make a hole at the center by piercing sharp end of scissor.

    • Repeat the above step for the other side of the small straw.

    • Now insert this straw on the diamond hole created on the other straw and then insert thin binding wire .

  7. Make 1-2 small loops at the end of the wire by using thick binding wire for looping . Similarly make 1-2 loops at the other end  of the fan easily moves around the two loops made. Similarly make 1-2 loops at the other end  of the fan easily moves around the two loops made.
    • Make 1-2 small loops at the end of the wire by using thick binding wire for looping .

    • Similarly make 1-2 loops at the other end of the fan easily moves around the two loops made.

  8. The wire inserted through the fan should be straight between the two loops. Bend  thin binding wire (about ~ 5-6 cms) where the fan loop ends  of wire at right angle . Bend 2 cms of thin binding wire again at right angle .
    • The wire inserted through the fan should be straight between the two loops.

    • Bend thin binding wire (about ~ 5-6 cms) where the fan loop ends of wire at right angle .

    • Bend 2 cms of thin binding wire again at right angle .

  9. Take a thin binding wire and pierce a hole  at the top end of half straw. Insert the thin binding wire attached to fan from open end of the straw so that the wire protrudes out through the straw.
    • Take a thin binding wire and pierce a hole at the top end of half straw.

    • Insert the thin binding wire attached to fan from open end of the straw so that the wire protrudes out through the straw.

  10. Tape the ends of wire and straw. Tape the ends of wire and straw.
    • Tape the ends of wire and straw.

    • By blowing air through the straw , turbine spins.

    • Make sure the holes made in small straws are large enough.

    • The small straw and the half straw should be should be linearly aligned.

    • The wire should be straight and not bent so that there is turbine rotates freely in between the two loops made.

    • The wire pierced through the half straw should be fixed properly and must not move around.

    • Will the speed of rotation increase /decrease by adding more blades ?

    • Will the length of thin binding wire make a difference w.r.t Speed of the blades ?

    • Try to produce sound by nipping the corners of the straw in "V" shape (Oboe ).

    • Is it possible to produce sound as well as rotation of the blades at same time ?
