Push the red button to start a motor which demonstrates one cycle of the single pop bumper in slow motion. Push the blue button to put the two pop bumpers into action.
The single pop bumper moves through a cycle slowly bringing down a metal ring to push the ball away and then resets. The bumper pair demonstrate how quickly the cycle happens in real time. When the ball rolls back onto the skirt switch, it activates the bumper for another cycle.
Electromechanical Music Box
Push the yellow button on the front of the exhibit to energize the cam motor and start a cycle. One cycle is a complete 360-degree revolution of the cams.
The Galton Pinball
Launch balls by pulling back on the spring-loaded ball shooter at lower right. Feed balls to the shooter lane using center plunger. To reset the exhibit pull and hold plunger on far left until all balls drain to the bottom.
The first ball hits the number one pin and falls either to the left or to the right. That’s the same probability as a flipped coin landing heads or tails. As all the balls fall down, they hit each pin as though it was a coin toss... making the bell shaped grouping of balls at the bottom.
This self-running demonstration shows the reset cycle of an electromechanical pinball machine. This design was pioneered by the D.Gottlieb & Co. pinball manufacturer. The Visible Pinball and the game it was based upon, Surf Champ, both use this reset cycle design. This computer animation was produced by American Steve Fury and graciously loaned to the Pacific Pinball Museum to help interpret the Visible Pinball. A second video demonstrates the inner workings of a flipper mechanism’s two-coil system also used in these games.
The bells, chimes and bumpers are magnetic and can be placed wherever desired on the playfield. Pull and release the plunger to launch the balls.
Notice how your arrangement of the obstacles interact with the descending ball.
General laws of physics can be studied through this exhibit. Make music with the placement of the different tones.
