In the 1950's Frenchman
Arthur Granjean tinkered away in his basement on what he called L'Ecran
Magique, the Magic Screen. Voila! He showed the world its first Etch
A Sketch at the 1959 Toy Exhibition in Nuremburg, Germany.
Behind the glass screen
framed by the familiar red plastic lies a mixture of fine aluminum powder and
itsy bitsy plastic beads. The two knobs control a pointy stylus--hidden beneath
the glass--that scratches the aluminum off the screen, leaving behind a black
trail. Turning the Etch A Sketch upside down and giving it a good shake
smoothes the powder evenly across the screen, with the help of the plastic
beads. Ooh la la!
To save a drawing, the Ohio
Art toy manufacturer's technical support team simply says: Don't shake the Etch
A Sketch. But Etch A Sketch experts can permanently save true pieces of art by
emptying the aluminum out of a frame.
