Here is something I had not heard about until today: it appears that water infused with tiny bubbles (and I mean really tiny, with diameters near the wavelength of visible light), has many useful properties. My first glimpse of this was here. I’m curious to learn more.
Here’s a remarkable statement (my emphasis):
Some studies have shown that fish raised in an environment with fine bubbles more than double the weight and size of fish in a control environment.
Crikey! It’s getting hard to keep up.
