When you stop and think about bubbles, you realize that they’re everywhere: in the dishwasher, on the top of your beer, on the crests of waves, in the saliva between your teeth, and, of course, in bubble gun toys.
That means the physics of bubbles are important in all kinds of scenarios. With that in mind, researchers from the Université Paris-Saclay in France have made an intriguing discovery about the film surrounding bubbles.
This film can, in some cases, be up to 8°C (14.4°F) cooler than the environment around it, the researchers say. The findings build on previous investigations into how changes in temperature can trigger the thinning and evaporation of a liquid film.
