Etch A Sketch drew with aluminum dust held by static charge
André Cassagnes turned clinging powder into a no-parts drawing toy; Ohio Art's $25,000 bet became the top-selling toy of 1960.

the move
In the late 1950s André Cassagnes, a French electrical technician, was working with metal powders when he noticed something odd: press a mark into a coating of aluminum powder and it showed through the other side of a translucent plate. The powder clung to the surface by electrostatic charge — and that cling, he realised, could become a mechanical drawing toy with no spare parts.
He called the invention L'Ecran Magique, the magic screen, and introduced it at the International Toy Fair in Nuremberg in 1959. Most manufacturers passed, deciding he wanted too much money. The Ohio Art Company took a second look and paid $25,000 — more than it had ever spent on a license — renamed the toy Etch A Sketch and began mass production later that year.
The mechanism was brilliantly simple: aluminum powder and tiny plastic beads are sealed inside a clear screen; two knobs control horizontal and vertical rods, and the stylus where they meet scores a line across the powder on the reverse side. Shaking the toy erases the picture, so it never runs out and never needs parts.
Saturation television advertising made Etch A Sketch a must-have for Christmas 1960, and it became the top-selling toy in the United States. More than 100 million have been sold, and Spin Master acquired the naming rights and design in 2016.
why it works
- Static charge needs no battery, motor or refill — the physics is the product
- Two knobs map to x and y, so any line is drawable by the user
- A shake resets it, which is both the eraser and the hook for endless redraws
- Ohio Art's $25,000 license bet was repaid by a decade-defining toy
what transfers
Use the physics people already have in their hands: a phenomenon that needs no power supply or replacement parts becomes a product that never breaks and never needs refills.
what came after
Etch A Sketch sold more than 100 million copies, was named one of the most memorable toys of the 20th century by the Toy Industry Association, and got a second life through Toy Story appearances. Spin Master acquired the rights and design in 2016, and the electrostatic drawing screen still works exactly as Cassagnes designed it.
