Control Resonant: How to Solve the Testing Facility Pearl Soda Dispenser Puzzle

The Testing Facility Pearl puzzle appears during the Unsupervised Science: Shut Down the Experiments mission in Control Resonant. To end the experiment, you have to reset every marked zone in the room to its default object, then trigger the shutdown from the control console.

Quick answer: Change every shifting object into a Soda Dispenser (THIRST STATION), drop one into each yellow floor and platform square, then pull the lever at the main console to shut down the experiment.

What the shutdown requires

The Shutdown Instructions document sits on the desk inside the control booth, next to the yellow monitor and the “TESTING FACILITY PEARL” sign. Read it first. It states that all designated impermanence areas must be in their default state, and that the default state is set as a Soda Dispenser. Only after every marked area holds a dispenser can the lever start the shutdown.

The placement points are the yellow painted squares spread across the metal floor and the raised platforms near the stairs. Each square needs exactly one soda dispenser sitting inside it.

How shifting objects change form

The objects scattered around the room are shifting objects. Every time one takes an impact, whether you throw it with telekinesis or drop it hard against the ground or a barrier, it advances one step through a fixed cycle of shapes.

The form order runs in this sequence:

Crate / Printer
Sink / Cabinet
Stove / Oven
Soda Dispenser (THIRST STATION)

It usually takes up to four impacts to bring an object back around to the Soda Dispenser form. Keep slamming or throwing the same object until the “THIRST STATION” label shows, then it is ready to place.

If a shifting object is already resting inside a square in the wrong form, carry it out, cycle it, and only set it back down once it reads THIRST STATION.

Solve the Testing Facility Pearl puzzle

Grab a shifting object from the elevated metal walkway. Drop or throw it repeatedly so it cycles through printer, sink, and stove until it becomes a soda dispenser.

Carry the finished dispenser to a yellow square on the lower floor and set it inside the marker. This clears the first placement point.

On the way to the stairs, turn the next object around. Afterward, put the dispenser onto the yellow square on the raised metal platform next to the staircase.

Work through the remaining objects across the walkway, corridors, and lower areas. Move any misplaced sinks, stoves, or printers out of the squares so you can isolate the dispensers.

Keep converting and placing until every yellow square, including the corner marker and the one near the console wall, holds a soda dispenser. No square can be left empty or holding the wrong shape.

Return up the stairs and cross the barricades back into the control booth. Interact with the lever on the control console to start the shutdown.

How to confirm the shutdown worked

When every square is correct and you pull the lever, the game shows a Quest Log Updated prompt and the sealed door opens. If the lever does nothing, a square is still empty or holds an object that is not a soda dispenser, so check the room again and re-cycle that object.

With the door open, run up the stairs into Evacuation Zone 5, break the obstruction inside, and collect your rewards.
