Deluxe Loop The Loop Apparatus

This high-quality apparatus easily demonstrates the transformation of potential energy to kinetic energy. Use the built-in ruler to measure the distance (in centimeters) the ball has dropped from its starting point at the top. We feature a two-sided back drop plastic disk that allows for measurements in degrees or cm when the ball traverses the loop. Includes two steel balls, 1 rubber coated ball, sturdy wood base and instructions.
