2. Take the eraser from the blackboard.
3. Zoom out and turn right. Tap on the cork board to the left to see a clue:
4. Turn the cork board over to find a plate. Take it. It has an A on one side and a 4 on the other.
5. Turn right. Zoom in on the top of the right cabinet. Open the left door and move the box to find the lid of an alcohol lamp.
6. Turn left and look up near the ceiling. There’s something up there but you can’t reach it. Use the eraser to knock it down.

11. Tap the blackboard, then tap the desk to see behind it. There’s some words written on the left corner:
12. Also, there’s some kind of mold:
13. Turn to the screen with the cabinets, where you found the lamp. Open the bottom of the left cabinet to see a train. Remember the clue from the table? Trains are aluminum. The book told you that Aluminum = Al. So type Al (that’s a lowercase L) into the keypad on the train and press enter. The train will move.

20. Open the drawer to find another keypad to unlock. Remember the drawing on the floor? Compare that with the plates to get the code:
21. Open the box and take the screwdriver from inside.

29. Inside is a small keyhole. The key you have doesn’t fit it. But I’d you knock off a piece of the key with the screwdriver, it will fit. You’ll hear a clicking sound.
30. Open up the backboard and take out vial B.
31. Remember the note from the cork board?
32. Use the pipette on vial A. Then use the pipette on the empty beaker to fill it with liquid from vial A. Then repeat. Do the same for vial B three times. If you do it right, you’ll get a green liquid:
33. Use the dissolvent to dissolve what’s stuck inside the alcoholic lamp lid.
34. Zoom out. Look on the table to the right. There’s a lit alcoholic lamp. Place the lid on it to put out the fire. Then take the pink flask with distiller water inside.
35. Examine the flask. It says it’s gradually solidifying. Maybe we can use it for something!
36. Remember the mold behind the desk? Go to it and pour the liquid into the mold.
37. Zoom out and then zoom back in on the mold. Take out the fork-shakes object you just made.
39. Turn to the blackboard. There’s an outlet underneath it. Plug the cord in and it will connect to the device on the desk.
