Welcome to The Lab, one of the more logic-heavy puzzle rooms in Escape Simulator. This room mixes chemistry, electronics, and robotics in a series of puzzles that require observation, experimentation, and understanding how different elements interact. Here’s how to solve it from start to finish.

---

1. Start with the Color Keypad Puzzle

• Find three colored molecule models (red, white, blue).
  • One is displayed.
  • Two are in a nearby drawer.
• Read the Medical Log on the tablet — it explains that each molecule has a different number of colored nodes.
• To solve the keypad:
  • Red: 3, 3, 2 → Outlier is 2
  • White: 4, 3, 4 → Outlier is 3
  • Blue: 2, 3, 2 → Outlier is 3
• Input 2 – 3 – 3 into the keypad.
• Unlocks a cabinet with a controller and blowtorch.

2. Controller Puzzle: Periodic Table Math

• Inspect the back of the controller to find a glowing panel.
• It shows numbers tied to element abbreviations from the periodic table.
• Examples:
  • O = 8, Ne = 10 (from “ONE” = 1)
  • Th = 90, Re = 75 → “THRE” ~ Three → 3
  • Es = 99, IIX = 119 → “SIX” → 6
• Final passcode: 1 – 3 – 6
• Unlocks controller access to devices — connect to the Robot Vacuum.

3. Clear the Vent with the Blowtorch

• Inspect and activate the blowtorch by pressing the red trigger.
• Use it to trace and melt the grate over the vent.
• Also burn the grate blocking the nitrogen storage room in advance.

---

4. Use Robot Vacuum to Reach Nitrogen

• Navigate the robot through the now-open vent.
• The controls are clunky — guide it to hit the table leg inside the side room.
• This knocks the nitrogen canister to the floor.
• Retrieve the nitrogen and bring it to the main workspace.

5. Craft Sodium Aluminate (for Crystal Recipe)

• Check the recipe: Sodium Hydroxide + Aluminum = Sodium Aluminate
• Get Sodium Hydroxide from a drawer.
• Get Aluminum scraps from the metal recycling bin — use only the small pieces.
• Use the machine:
  • Insert sodium hydroxide.
  • Place one aluminum scrap in the slot.
• Combine to create Sodium Aluminate.

---

6. Craft the Crystal

• Insert both Sodium Aluminate and Nitrogen into the machine.
• Use the provided tiles to recreate the shape shown on the Post-it Note:
  • Start with corner and edge pieces.
  • Continue building out the crystal’s structure using trial-and-error.
• Once completed, drag the crystal slot scanner into position.
• Insert the crystal and begin the repair.

---

7. Craft the Coolant

• Remove the crystal and clear the shape tiles.
• Retrieve Helium from the table and insert it into the machine.
• Use new shape tiles to recreate the coolant’s diagram:
  • Match hard edges, peaks, and troughs as shown.
  • Complete the design.
• Insert the final shape to create the Coolant.
• Plug it into the bottom slot under the central device.

---

8. Escape

• Once both the Crystal and Coolant are installed, the center crystal fills up.
• This unlocks the main escape door.
• Exit and complete the room!

Tips for Success:

• Periodic table matching requires attention to both symbol and atomic number.
• Use trial-and-error on shape-building puzzles.
• Navigating the robot can take a few tries — keep at it!
