Pieces bob on the waves, bubbles rise. Drag anything to splash it around.
Google Underwater sinks the page into a blue ocean: the pieces bob on the surface, bubbles rise, and everything you throw makes a lazy splash back to equilibrium. Press Dive above and drag things around — it’s the most relaxing member of the gravity-trick family.
The story of the trick
“Google Underwater” (sometimes “Google Gravity Underwater”) became a viral search alongside Google Gravity in the early 2010s — fan-made physics demos of the Google homepage hosted on mirror sites. The underwater version added buoyancy: instead of falling, elements float with a gentle wave motion, and searching was rewarded with fish swimming across the results. Google never made it official, which is why it survives on pages like this one.
How buoyancy is faked on a screen
Three ingredients: a slight upward acceleration (the opposite of gravity), a sine-wave nudge so pieces bob rather than rise in straight lines, and heavy damping so throws die out like moving through water. Add rising bubbles on a loop and the illusion is complete — your brain fills in the rest.
More of the family
Google Space removes gravity entirely, Gravity drops the page in a heap, and Askew just tilts it enough to make you doubt your monitor. All self-hosted, all playable.
What is Google Underwater?
A browser physics trick where page elements float and bob as if submerged, with bubbles rising — a fan-made demo in the Google Gravity family.
Does searching Google show the underwater effect?
No — it was never an official feature. The effect lives on independent demo pages; ours is self-hosted and playable above.
Can I move the floating pieces?
Yes — drag and release. Water damping slows every throw, so pieces settle back into a gentle bob.
Why do the pieces bob up and down?
A sine-wave offset is added to their position each frame — the same simple math behind most floating animations on the web.
