Abstract

Artists, using empirical knowledge, manage to generate and play with giant soap films and bubbles. Until now, scientific studies of soap films generated at a controlled velocity and without any feeding from the top, studied films of a few square centimeters. The present work aims to present a new setup to generate and characterize giant soap films (2 m \(\times \) 0.7 m). Our setup is enclosed in a humidity-controlled box of 2.2 m high, 1 m long, and 0.75 m large. Soap films are entrained by a fishing line withdrawn out of a bubbling solution at various velocities. We measure the maximum height of the generated soap films, as well as their lifetime, thanks to automatic detection. This is allowed by light-sensitive resistors collecting the light reflected on the soap films and ensures robust statistical measurements. In the meantime, thickness measurements are performed with a UV–VIS-spectrometer, allowing us to map the soap film’s thickness over time.

巨型肥皂膜表征的新设置

摘要

艺术家利用经验知识，设法产生并玩弄巨大的肥皂膜和气泡。到目前为止，对肥皂膜以可控的速度产生且没有顶部进料的科学研究一直在研究几平方厘米的膜。本工作旨在提出一种新的装置来生成和表征巨型肥皂膜（2 m \（\ times \）0.7 m）。我们的设备安装在一个湿度控制箱中，该箱高2.2 m，长1 m，大0.75 m。用各种速度从起泡溶液中撤出的钓线夹带肥皂膜。通过自动检测，我们可以测量生成的肥皂膜的最大高度及其使用寿命。感光电阻可以收集肥皂膜上反射的光，从而确保可靠的统计测量。同时，使用UV-VIS光谱仪进行厚度测量，使我们能够绘制肥皂膜随时间变化的厚度。
