I'll give it a try. Actually I don't think I have ever seen a cloud of any kind since I started using the silverpuppy.

Without using silver? Put something in the water that has a near neutral to slightly negative bouyancy. A small piece of paper well soaked?

I mean, do you put a glass on the heat source and add something to the water so you could see the stirring effect? I have actually seen the effect with flakes of silver in the water when I didnt wipe the electrodes and let it run for about 3 hours. Looked neat. I just wondered what method you used to observe cause I get asked how I know its working all the time and I would like to show those who inquire without having to use silver.

Going the other way with liquid cooling [vs heating], you get pretty much the same central updraft as the cool liquid on the outside edges sinks, forcing warmer liquid up through the center and back around to the outside top. Preheating and allowing to cool works pretty well for stirring, but tends to peter out as the container gets cool too fast. Both directions ..hot to cool or cool to hot..give the same thermal torrid in the same direction. So, if it seems that heat is gaining too much, Let it cool and you still get a thermal stir effect. It's not heat itself that does the job, it's the thermal differential, or difference in heat. Which also means that a cool room adds to the effect.

In a cylindrical vessel heated at its lower end, the steady-state convection will be an updraft vertically along the center axial region, and a downdraft along the periphery of the cylinder except for cooling losses at the top surface. A glass lid will diminish the latter loss, thereby increasing the convection down the inside periphery of the vessel. The result is more stirring without additional heating.
