A couple of dozen octopuses at aquariums around Europe have been given Rubik's cubes to play with. It's not to find out of they can solve them (although it would be SO cool if they did), but to see if the animals favor one arm (or two) over the others. Visitors will be asked to observe which arm they use when playing with the puzzles. The results will be used for research, but also to make the octopuses' lives easier and more enriched.
