Apologies for the poor quality of the images and video; I'd left my camera in the car, and so only had my flip phone. ** Here's something randomly fun - I discovered that I had two partially-used bottles of hand sanitizer. I decided to mate the bottles so that I could get rid of one. I figured that by the time I got off shift, they'd be done. They weren't.  If you look closely, you can see that the material in the top bottle is still in place at the "bottom", right where it should be. The only thing I can figure is that somehow when I put them together, I did so in such a fashion that the air pressure from the bubble actually pinned everything in place instead of letting it flow. I did scrape off excess material from the pump mechanisms on the rims of the openings, so perhaps that allowed for an airtight seal of some sort. The only way for me to get things to flow was by pulling the bottles apart and squeezing the top bottle (see video), then putting them back together: Odd, eh? |

I would be inclined to suspect surface tension was also involved.

Here's the highly scientific explanation.
The stuff's too thick.

there's a phenomenon called "perched water table"
common wisdom used to be that you would line the bottom of a flower pot with gravel with the intention that it would help it drain better.
studies determined that not only would the water not drain out of the soil, better; the wet zone in the soil would be the same size - meaning that in a 12 inch deep pot full of soil with a three inch wet zone, all adding another three inches of gravel would do is raise the wet zone to six inches off the bottom. - basically, it wasn't that the bottom of the pot was stopping the water getting out - it was that the water didn't want to flow out of the bottom of the soil layer.

Also, part of my Filter plant on my pond utilises air-stones to create flow.
Air pushes water UPwards, so an airstone below the outflow from the filters will help mix up the filtered water with the existing water, and increase the flow of that, which helps circulate the pond.
MB/s did do an excellent thing with a large rig to show water circulation inside a bubble field didnt they?..

If I remember right, the myth was you cant swim in "Fizzy" water, because you will sink. It was disproved, because it just wasnt valid. |
