Also the physics of the microdroplets above the hot tea is super interesting.
If you like this, check out antibubbles[0]. I discovered them for myself as a kid, playing around with soap water & pipettes. If you make a glass of water with half salt-water at the bottom, and inject a solution with intermediate density, the antibubbles will settle at the interface between the layers. They can last for several minutes.
