Over the weekend, I mixed up two batches of Charmy-based bubble juice. One was diluted at 33:1 (water:detergent) and the other at 50:1. Both used 1/4 heaping teaspoon guar/liter of water and 1/2 heaping teaspoon Rumford baking powder.

Time: 8 am. Temp: 65F. Humidity 70-75% RH. Sunny.

The 50:1 was able to make some 20+ foot tubes with a nominally 32-inch (actually 29 inch) top-string modular loop (rayon mop top-string, BBB twine bottom). Closing 20 foot tubes was not a problem. I could get four or more nice-sized spheres per dip. The colors of all were rich and weighted towards green/red indicating a thick soap film. With a 72-inch top-string loop, it was very hard to close bubbles as the film popped (at the front) on closing. At this dilution, the giant bubbles were not terribly practial. The tubes maintained their rich color through their entire length.

This was a good session to demonstrate how dilution influences color. The full-soon washes out the color -- so the colors do not appear as vibrant as in recent sessions that were done on cloudy mornings.
