The Slow Mo Guys teamed up with Caltech physicist Peng Wang to capture an extraordinary video of light traveling through a bottle, using a camera capable of recording at 10 trillion frames per second—around 20 million times faster than their regular equipment. The stunning 2,000-picosecond footage shows light in motion, a feat made possible by Caltech’s Compressed Ultrafast Photography technology. Since the camera only detects light, the bottle was added digitally in post-production.

Viewers were left amazed by the surreal clip, describing it as “mind-blowing” and a rare glimpse into a phenomenon that happens faster than the human eye can comprehend.

In related news, Italian researchers recently achieved another light-based breakthrough: they created a “supersolid” form of light—an exotic state of matter that flows like a liquid but maintains the structure of a crystal. Both advancements push the boundaries of how we understand and manipulate light in physics.
