Now move onto the gas globe. Face the globe and take a step right. Face the globe and press on the black scarab to close the windows so you can use the levers. Go back to the levers and from left to right set them so that they are all, half, all, all and none. That's air sorted.
Next stop is the flute and fountain room for the water element .
This is on the left, past the four coffins. You should find a flute player and seven fountains. Each fountain plays a note which will match the flute player. You will now be in the chair room. Click on the hourglass to make the chair appear.
