This is a rather devious (read hard...very hard) puzzle by master puzzle designer Wil Strijbos. The puzzle begins with a metal disk impaled with a solid spike. Just free this disk! Well... that is only the beginning. Just like the mysterious blue lotus, more perfection lies within.... No banging, wrenching, magnets, or tools are required. Just patience, careful observation, and close attention to every nuance and movement this puzzle makes. Blue, like the lotus, this is perfection itself. Manufactured of anodized aluminum... and guile. Happy Puzzling!
