A photorealistic still life featuring a kinetic sculpture chain reaction including a marble run, a pinwheel, dominoes, and a knife cutting butter.

A marble is released from a height and rolls down a spiral ramp. Gravitational Potential → Kinetic 2 The marble strikes a pendulum, causing it to swing. Kinetic → Mechanical Potential 3 The swinging pendulum hits a small ball, propelling it forward. Mechanical → Kinetic 4 The ball rolls down a ramp and hits a lever, causing it to pivot. Kinetic → Mechanical Potential 5 The lever lifts a small weight attached to a string. Mechanical Potential → Gravitational Potential 6 The weight drops, pulling the string that activates a switch. Gravitational Potential → Kinetic → Mechanical 7 The switch turns on a motor, which spins a fan blade. Electrical (from battery) → Mechanical (fan) 8 The fan blows air onto a pinwheel, causing it to spin. Mechanical (fan) → Mechanical (pinwheel) 9 The spinning pinwheel knocks over a domino, initiating a chain reaction. Mechanical (pinwheel) → Mechanical (domino) 10 The final domino hits a knife, which cuts a stick of butter, and the piece falls into a pan. See more
