Such a puzzle! How does the illusion work?
This wind spinner is a solid stainless steel spiral holding a high quality crystal glass ball.
As they spin, the optical illusion appears - the ball appears to roll smoothly down the spiral, yet never reaches the bottom. On opposite rotation, the ball now seems to defy gravity and float weightlessly upwards! They are truly mesmerizing and capture the attention of everybody watching.
Size: Top to bottom 310mm. Diameter of sphere 40mm.
