* A few prisms, * A sunny day, * Threads to hang prisms.
Hang the prisms with thread near the window of the room in your house. Just see what you did and wonder how it all happened – rainbows all round your room.
Light is not white, but a merge of different colors as in a rainbow. A prism helps to disperse or bring out the different colors and create beautiful rainbow of colors.
The prisms bring out the various colors of lights that we think is white and helps you find rainbows in the room.
