Introduction

Variant of "Light - Newton Pencil Spinner", made using a twig instead of a pencil

    • Use the cutter with utmost care. Always make sure you are cutting away from your body with only a max of 2 cm of the cutter blade exposed. Use a solid surface (floor or table) when you are using the cutter and do not cut in the air. While cutting, place the items as far away as possible from other parts of your (or others’) body.

    • Handle the scissor with care

    • Be mindful of the all pin

  1. To make the notches, place the cutter at an angle over the twig and press down steadily so as to get a slanted cut
    • To make the notches, place the cutter at an angle over the twig and press down steadily so as to get a slanted cut

    • Make another cut with the opposite slant, about 2-3 mm away from the first cut so that the cuts meet near the core of the pencil and you get a neat `V’-shaped notch

    • Leave a gap of about 2 mm between the notches

    • Cut different kinds of spinners/fans, using cardboard (rectangular, circular, star shaped etc), each having a diameter of 5-8 cm

    • Make a hole in the centre of the fan with a paper puncher

    • Insert the pin with the fan at the end of the twig where you have made the notches. Note that since the twig doesn’t have an eraser, inserting the pin presents a different challenge. Inserting the pin directly into the twig should be possible, but if that’s proving difficult, you may use tape to stick the pin onto the twig

    • This will show you that in essence you can make this toy even on a simple pencil, one without an eraser

    • With one hand, hold the twig as far away from the notches as possible, but with a firm grip. In the other hand, hold the ice-cream stick piece very firmly and rub it back and forth, with pressure, on the notches. The fan should start to rotate fast and freely.

    • Holding the ice-cream stick too loosely and far away from the notches

    • Notches are not deep enough

    • Notches are too far apart or too few

    • Notches are not at the end of the twig

    • Fan is too big/heavy.

    • Hole in the fan is too small or not centred.

    • Not rubbing with optimum speed, pressure or vigour

    • How can you change the direction of rotation? Try applying pressure at different zones of the notches to see if you can change the direction. Also try rubbing from one direction and not the other.

    • Can you make it spin even if you hold the pencil vertically?

    • Which kind of fan goes the fastest?

    • Compare the speed of the spinners to those in the Primary Tactivity
