Follow the Bouncing Ball

A drop makes waves – just like quantum mechanics?

This simple experiment creates a surprisingly complex coupled system of the driven oscillator that is the oil and the bouncing droplets. The droplets create waves every time they hit the surface and the next bounce of the droplets depends on the waves they hit. The waves of the oil are both a result of the bounces as well as a cause of the bounces. The drops and the waves, they belong together.

Does it smell quantum mechanically yet?

This looks pretty cool (watch the video in the link) but I share Bee’s skepticism that this explains QM; it reproduces a few of the basic behaviors, but that’s a far cry from explaining all of it. I think it’s a tendency of human nature to become enamored of what works and conveniently ignore what doesn’t, but as scientists we have to make sure this isn’t happening.
