how about a weight on a string (pendulum). You can make it hit a ball and send it rolling.

Sources of potential energy are stored in gravitational or that of a spring. By going down a slide, a child starts wtih no speed and gain speed at the bottom, which is turning potential energy to kinetic. Attach a bob to a string forms a pendulum. The bob has the highest speed at the bottom, where its potential energy is least.

A pendulum. Hold the weight up at a specific height, then release and watch the pendulum swing. As it passes the bottom of the swing it is changing kinetic energy back into potential energy.

A PENDULM. TIE A BALL TO THE END OF A STRING AND LET IT DROP WHILE HOLDING THE OTHER END OF THE STRING. WHILE THE BALL IS STILL IN THE AIR NO MATTER AT WHAT DEGREE, IT WILL STILL POSSESS BOTH KINETIC AND POTENTIAL ENERGY. ONCE THAT BALL HAS REACHED THE LOWEST POINT (WHICH SHOULD BE PERPENDICULAR TO THE FLOOR) IT IS THEN WHEN THIS "MACHINE HAS PURELY KINETIC ENERGY.
IM AN ENGINEERING MAJOR AND THINK THIS IS SIMPLE YET A PERFECT DEMONSTRATION OF BOTH KINETIC AND POTENTIAL ENERGY.
GOOD LUCK

Bounce a rubber ball that starts a marble rolling downhill that trips a switch that turns something on.
