Experiments 2
video clip of oscillating pentagonal frame
The majority of bubble film experiments in the period 1993-1995 were performed on electromechanical apparatus where one side of the geometric frame was fixed. A variable speed AC motor drove a rod attached to the hinged support structure of the bubble frame. While oscillations were not distributed equally to all sides of the polygonal frames, the elasticity of the bubble film compensated for the restriction during cycles. Other apparatus (see photo-Experiments) included acoustically driven modes of vibration with supporting stand.
The following frames show the wide variety of phenomenon recorded from these experiments of both curved and flat bubble films.
evolving large ring and nucleus
inflow of fluids in rotating 3-arm spiral changing to 2-arm system
evolution of 3-arm system to 2-arm (note-angularity of arms)
rotating 'propellers'
more propellers and rotating rayed nucleus structure
rotating stars in curved pentagonal frame and oscillating fluids in 7-sided flat frame
cyclonic/ring-type rotational waves
more rotating and oscillating cyclonic sections
oscillating multiple bubbles and micro-bubble films
colliding fluid streams in bubble film
more colliding streams
colliding nuclei (without any interactions)
