You must separate all pieces and then put them back together. Named after the first satellite put in orbit, this laser-cut wood and metal puzzle was originally designed by Leonard M. Lyon in 1891 and later adapted by Jean-Claude Constantin. The outer ring appears to block any attempts to remove the inner ring, no matter which way you turn it. It seems impossible, but it can be done!
Jean-Claude Constantin lives in Germany, where he designs and manufactures many different laser-cut wood puzzles, as well as metal puzzles and magic tricks.
