Put your finger through a thin soap film and it’ll pop out of existence in the blink of an eye. Physicists have recorded exactly how this behaviour occurs using high-speed cameras to see how the soap film retracts when it is punctured.
How far can this technique be pushed? Is it possible, for example, to release one edge of a flat soap film and record how it retracts?
The conventional view is that this kind of experiment is impractical because edge effects make a perfectly straight rupture impossible.
