Pubity on Instagram: "😲 Oxygen can look shiny underwater because tiny bubbles bend and reflect light much more strongly than the surrounding water, creating bright, mirror-like surfaces. The smooth bubble walls act like miniature lenses that catch light and send it back to your eyes, so even a small cluster can appear silvery. This effect is especially noticeable when bubbles rise quickly or gather on surfaces, making the oxygen seem to sparkle underwater. (@norinsmarine via ViralHog) #surprise
