Bottle Puzzle (Glass Liquid Sound) — Floor 3

The bottle puzzle is the Glass Liquid Sound Puzzle, reached after leaving the Floor 3 elevator through the blue Triangular Stone door. The puzzle asks you to match the tone of a bell on the bar counter by adjusting the liquid level in a giant glass pitcher.

1. Pick up the first Bottle to the left as you enter.
2. Step into the bar and collect Bottles from the bar table, behind the counter, and in the bathroom.
3. Ring the bell at the counter once and listen to its tone.
4. Fill the giant glass pitcher with Bottles until its tone is close to the bell's.
5. Hit the pitcher with the Wrench to test the tone.
6. Use empty Bottles to remove liquid until the pitch matches the bell's exactly.
7. When the tone matches, ring the bell again — the glass shatters and drops a USB Cable.

The exact tone sequence is randomized on each playthrough, so the number of Bottles you add or remove changes run to run. The Wrench is required to test the pitch. See Wrench weapon for the pickup location.

The USB Cable dropped at the end combines with the USB Adapter picked up near the boarded door above the dining room to create the USB Charger used in the projector room puzzle.
