According to Viktor Schauberger, spiral, vorticial motion enhances water life giving property. Falling water droplet spins as it encounters air resistance, it is also in spiral, vorticial motion. So I made a hole in the cap of a bottle of water and inverted it.
Lo and behold, a vortex forms at the top of the aquarium sponge and flickers as the water drips.
How do know that it is life giving? Should I turn off the filter and all aerations? What's IV drip anyway? Why drip?
NOT A VORTEX, JUST A REFLECTION. NOTICE, NO BUBBLES.
