Marcel Wanders: SPARKLING CHAIR 2010. Stedelijk, Amsterdam. “The Sparkling Chair is made out of PET and produced using the same blow molding technique commonly used for bottles of water. After blow molding the legs and seat, the hollow space is filled with high pressure air which creates very strong and structural components.With this technique the plastic usage is minimal and the total weight of the chair is only around 1kg. Finally the legs are screwed onto the shell. It’s as easy as drinking a glass of water.”
