When a printer reports an ink cartridge needs replacing as it is “empty” I wondered how much ink there was actually left in the cartridge.
The answer is surprising – quite a lot. Certainly enough to use in some artistic endeavour.
Fill a few jam jars with water, drop some ink cartridges in and wait for 24 hours. The result is some beautiful, vivid water-based inks to use.
That was the easy bit. The next stage needs a bit more imagination :o)
