The clue is on the elevator door.
Get an empty test tube on the left.
You must get solutions on the right and mix it in the empty jar.
From top to bottom:
- 2 tubes
- 1 tube
- 4 tubes
- 3 tubes
Make sure everytime you get a tube, pour it to the jar to have some space for the next tube.
Shake your device. You should see a yellow colored liquid inside the jar.
Equip your empty tube and tap the jar. Use the filled tube at the lock.
Elevator opens. Welcome to level 58.
