Copper Sulfate Crystal Apartment

Do you love crystals enough to coat every surface of your apartment with them? Artist Roger Hoirn sealed a first floor flat and poured ~90,000 liters of hot supersaturated copper sulfate solution into the apartment. Did the technique work? Judge for yourself! I found one youtube video that shows a child in the flat and another that sort of pans around the apartment, or if you happen to be in the Elephant & Castle of London, go have a look. You possibly don't want your dwelling to be covered in blue crystals, but you can easily grow some copper sulfate crystals of your own.
