At Tinka, one of the last surviving marble factories in Latin America, Victor Hugo Chiarlo, has been making little glass balls for more than 50 years. He is trying to preserve a childhood classic that is at risk of disappearing.

“You know what killed the marble?” he asks. “Pavement. Marbles need dirt floors.”

But this art is not dead just yet. Watch Mr. Chiarlo brings a little bit of magic to Argentina as he heats glass to 1500 °C and creates the little spheres that have brought happiness to generations of children.
