Quantum physics is fundamentally weird, so much so that we need thought experiments of hidden cats in boxes and metaphors of spinning coins to even begin to comprehend its laws.
Yet even in our classical world, where physics is more intuitive, shades of quantum behavior can be represented using relatively simple scenarios.
Researchers experimenting with tiny droplets of oil running down two adjacent channels in a bath of vibrating fluid have discovered that the behavior of the droplets matches up with a famous quantum thought experiment.
