It is a calm and dark night. A water fountain ( shown as a square in center) is trickling.
The water fountain has a saturated solution of castile soap (fine, hard white or mottled soap made with olive oil and sodium hydroxide) with added glycerine at 5% of soap solution volume. A garden hose runs from the pool to natural gas valve at the house.
We crack open the natural gas valve and soon the air is filling with bubbles. Now, turn on colored flood and spot lamps and check out the colored bubbles slowly rising in the air (natural gas is lighter than air).
Perhaps, a few custom colored bulbs with white lights shining through the colored Cellophane? As the bubbles ascend in the sky we turn on a couple of oscillating fans and as they pick up speed switch on the floodlights mounted on fans (our panning light effects).
Time to sit down, relax with a hot or cold drink and think of....bubbles in the night...
