Watch this video to the end. Don’t worry about stopping it or something, you’ll manage to read the few lines below while things build up. Do you know what will happen?

Now, if you’ve seen this before at your local science center, then you may not be surprised at what happens. You may have even seen it somewhere on YouTube and know what’s coming.

Still, can you explain to me in a non-trivial way exactly why things are happening like this? 😉

See, you don’t need to delve into quantum physics before things become unintuitive and rather weird. Case in point: fluid dynamics.
