The Soap Bubbles Art

Megumi AKASHI Hokkaido University

Abstract

The Soap Bubbles Arts are art works drawn by flows on a film of soap bubbles.

Gravity, a breath of air, heat, evaporation of water, and Marangoni effect cause complex flows on the film and we can see flow patterns shining like a rainbow with illumination by a light in a dark room (Figure 1).

A method of drawing the soap bubbles art is as follows. First you simplify a drawing you choose (Figure 2). Second you put it on a ramp and illuminate the drawing in a dark room. Third you set the film of soap bubble near the ramp and you can see iridescent flows on the drawing projected on the film. Finally you enjoy seeing the scene and taking pictures to leave the scene as your work. Because the flow is unstable and you never see the same scene. I think this is the most important point of this art.

I produced some works using drawings of great painters. For making “The scream of convection” (Figure 3) from “Scream” by Edvard Munch, I modified naturally appeared flows by heating the frame of film to express the scream of nature. In addition to this, I made “The land scape of convection” (Figure 4) from the drawing of Vincent Willem van Gogh and “The lady of flow “(Figure 5) from “La Gioconda” by Leonardo da Vinci with challenging of some ways to generate additional flows.
