DIY Newton's Disc : Step-by-step Instructions

Newton’s disc is a circular disc made out of 7 colors: Violet, Indigo, Blue, Green, Yellow, Orange, Red with the equal partition. The disc turns out to white when rotated at speed. With this, Sir Isaac Newton has proved that white color is a combination of 7 colors and so it is called Newton’s color disc or disappearing color disc.

Draw a circle on a card paper using a rounder. Divide it into 7 similar parts using a protractor.

The radius of circle should be 7cm & the angle between two lines should be 51.4 degrees.

Color the parts with VIBGYOR colors.

Cut the disc out using a scissor.

OR you can download the disc, print & color it as given.

Snap the circuit: Power + Motor.

Connect the gearless motor with the Motor Element.

Connect power bank with Power Element using USB cable.

Pierce the disc using a compass into the center of the disc and then insert the shaft of the gearless motor. Just take care that the hole remains tight to the shaft to make the disc rotate at adequate speed.

Arrange the disc with the use of blocks if required or you can carefully hold the geared motor using your thumb and fingers. Turn the power ON.

This way, Newton’s Disc is one of the practical ways to experiment with white light and its colors. It makes it easier for the kids to understand the composition of white light and how we can get white light from the colors of the rainbow.
