Suspended in space
I love the ephemeral nature of the soap film, and this quality is enhanced by seeing it suspended amongst more tangible objects.
As can be seen from above, quite a large area is now illuminated, thanks to help from a friend in the workshop. I still need to sort out exactly how to position the camera, but it was wonderful to watch the flow over a large area; how for instance descending flow interacted with flow rising back up from the bottom.
The dynamics of the flow are also interesting at the boundaries .. below is an image showing how the soap attaches to the string and the bubbles. The shape of the flow seems to be determined by these boundaries.
Below is a close up of streaming downwards from the bubble layer, top, defined by the scalloped edge
