[00:00:00]This cabinet opens when you push it closed.

[00:00:02]The push drives a hidden plunger inward loading a tiny spring behind the door.

[00:00:08]A sliding pin is the memory. It drops into one notch of the heart-shaped track holding the plunger back. On the next push the pin finds the exit ramp. The loaded spring kicks the door out. So the next click lets you predict the pop.
