You might think that all that can be done with soap bubbles is for kids. But it has been observed that observing light scattering through soap bubbles produces unexpected results which can lead to insights into complex concepts such as space-time curvature. What’s in it [stoppi] His latest experiment says – creating a “light crab” using a laser and a soap bubble. You can watch the video below, but a fair warning: if only videos with music bother you, you may want to mute your speakers before watching. On the other hand, it almost seems like a laser light show set for music.
The setup is simple and follows the procedure of the 2020 Israeli-American research paper. A relatively powerful laser pointer is connected to a fiber-optic cable through a focusing lens. The other end of the fiber provides light to the soap bubble, where it splits into strands that display something called branching.
Our knowledge of physics is not deep enough to explain what is happening here. However, if you are interested in reproducing this test, it does not seem to be something external. The original paper has a lot to say about this and if it is too heavy for you, there is always a Sunday supplement.
If there is ever a practical application for this, we will see an improvement in the design of the bubble machine. Oddly enough, this isn’t the first time we’ve seen a laser wedding with bubbles.
