ELECTRIC SPINNER FOR TEACHERS
DESIGNED BY US
This unit designed by us, helps to demonstrate Newton’s discovery that white light
is made up of the seven colours of the rainbow (spectrum) it is battery operated
and simply press the small red button and the disc will spin round fast, probably
faster than the hand held spinners mentioned earlier. So the disc will go even whiter
than the others. Good for demonstrating without having to make anything up. Comes
ready to use. You just supply the battery.(1 x AA)
