Chapter 8: The Time Machine.

  You have landed on a lower floor in the middle of all kinds of devices. In the middle is a boiler with a number of pipes connected to it.

3 devices are numbered 1 to 3 along the wall, zoom in on device 2. You see a pipe with four handles in the middle, on the left of the pipe you see a gear.  

Turn the gear and you will see a rack go down. If this is all the way down, the gear will come loose and you can take it.  

You also see that you can now move the 4 levers. If the gear is in your inventory, zoom in a bit further on the pipe. Pull up your magic lens, you see 4 blocks. 

They are quarter circles and there are 4 places where they can stand.  

Left front, left rear, right front and right rear. Those four quarters must now stand right under each other.

If you look at the blocks from above, you see where they stand.

Number the handles from top to bottom 1 to 4.

Leave 1 in the middle, turn 2 to the left, turn 3 to the right and 4 to the left.

You will see a liquid flowing through the pipe to the boiler in the middle, 1 of the 3 locks will open.  

Zoom out and turn to the right, you will see a fence with a piece of wall to the right.  

Go there and turn to the wall, you will see a lever on the left and a box with a hole on the right. Drag the gear to that box with the hole, then pull up your magic lens.  

You now see a mechanism, 8 bars with 2 notches. At the top you see a cross bar and a screw shaft below. If you pull the lever downwards, a rod moves upwards, lever upwards, then a rod goes down. With the gear you select the rod, 1 rod is already good. Number the bars from left to right 1 to 8, you now have to alternate bars up and down. Start at bar 6, lower the handle and the bar goes up. Now select bar 8, lever up and bar 8 lowers. Now select a next bar and then move the lever up or down depending on how the lever is positioned. The first 2 you have had, the rest of the sequence is: 6, 8, 4, 8, 4, 5, 3, 5, 3, 1, 2, 1 and 3. In between each time turn the lever.

Now there are all notches at the cross bar, the gate now opens.  

Go up the stairs, look to the right and double click on the microscope.  

You walk along the broken stairs to the table with the microscope, on the right on the table is a wheel with four handles. Take this wheel and read the letter, then zoom in on the microscope.  

Zoom even further into the test bottle behind the microscope, take this bottle.  

Go all the way back to the stairs you came up to and turn left. Go to the device with the ropes and the pulleys, zoom in on the front of the table.  

Drag the wheel towards the device in the middle at the front of the table. Turn the wheel clockwise until the middle part comes loose, take this piece.

It is a short thick bolt, a "Barrel Screw".

If you have looked closely, you have seen that outside a box is being hoisted inside.  

Zoom out and turn to the right, there you will see a little staircase with a device above it on the wall. Go there and see a spot for the thick bolt, drag this bolt towards it.  

Then turn the bolt clockwise, continue to rotate until the latch slides out and the rack is loose. Pull the rack to the other side, you will see a lever there. Pull the lever to the other side.  

The box that just came in is now put on the table. Zoom in on the bin with the box, in front is a wheel with 6 handles, take this wheel.  

Then take the wooden box out of the bin, then go back to the table with the microscope. Right at the table you see a square, drag the box here.  

Zoom in on the lock on top of the box and pull the latch to the right, the box will open. The front lens is pushed forward, look left along the lens and zoom in.  

Take the small lens that lies there. Zoom 2x out and then zoom in on the microscope, zoom in further on the top of the microscope. You see that there is a loose ring above the microscope, drag the small lens towards it. Then turn the ring with the lens for the opening.

Go back to the stairs and go down, go past the boiler to the pipe with the 3 above.  

You can see a handle at the top of the pipe with a number of gears underneath. Left is a wheel with 6 handles, now drag the wheel from your inventory to the shaft on the right.  

Pull up your magic lens and you will see 4 quarters again, you have to put these quarters right above each other again. Number the quarters from top to bottom 1 to 4  

The device works as follows, with the handle at the top of the pipe you determine which gear you can use. Handle to the left then use the left wheel and the blocks 2 and 4 are twisted.

  Handle to the right then use the wheel on the right and the blocks 2 and 3 are twisted. Handle in the middle then the wheels work together left and right and the blocks 2, 3 and 4 are twisted.

Block 1 remains in place and the rest must come underneath. You have to look at the blocks from above and from the side to see how they stand.

  Move the handle to the left and turn the left wheel until block 2 is right under block 1. 4 is now right under 3. Move the handle to the right and turn the right wheel until block 2 is right above block 4.

Turn the handle back to the left, turn the left wheel until block 2, 3 and 4 are right above each other.  

Then handle in the middle and turn with 1 of the wheels until block 2, 3 and 4 are right under block 1.

You automatically zoom out and you see liquid flowing through the pipe, also see that lock 2 on the boiler goes loose.  

The pipe leaks slightly, zoom in on the pool of liquid under the pipe. Drag the empty test bottle there and this will now be filled. When it is full it will disappear to your inventory.  

Zoom out and go back up, go to the microscope and zoom in on it. Put the test bottle in the rack behind the microscope.  

Zoom out and zoom in on the standard left of the microscope, the one with the flame and the mirror. Turn the mirror so that the light beam is focused on the lens, the test bottle is now also illuminated.  

Zoom out and go to the top of the microscope, zoom in on the lens. Turn the outer ring to focus the image, if the image is sharp you get a look at the base of the microscope.  

You see that a hatch has opened, zoom out of the lens. Then zoom in on the base of the microscope, in the opening is a star-shaped button. Grab this button.  

Zoom out and then look at the right side of the table with the microscope. Zoom in on that, you will see a spot for that button so drag this button there.  

Turn the knob over and a hatch will open, open the hatch further. You will find a handle there, take this handle.  

Zoom out and go back down, go to pipe 1 and zoom in on it. At the top is place for the handle so drag it to that, pull up your magic lens.  

You see again 4 quarters and you have to put them together again. Number the rings from top to bottom 1 to 4, on the rings are slots where the handle can go through.  

Call the handle A, then slide A to ring 1, it has 2 slots. You can move A to the left and to the right or in the middle.

Initial position: ring 1 slots on the left and in the middle. Ring 2 slots left and right, ring 3 a slot on the right.

Ring 4 also 1 slot this is in the middle.

Solution: A in ring 1 turn to the left, A to 2 and then turn to the right, A to 3 and then turn to the left.  

A to 2 and then turn to the middle and finally A to 4 and then turn to the right.  

You see fluid flowing through the pipe again, the final lock on the boiler opens. Turn to the boiler and zoom in on the 3 locks, pull the 3 handles down.

Slide the lid up, on top of the 6 turrets is a device with pieces of paper and metal rods.  

It is a model of a flying machine.  

Zoom out and go upstairs to the table with the microscope. Zoom in on the device that was hidden in the box, turn to the back.

You see a bottle with a purple liquid and a foot for a device. Drag the model to that foot, the model get into shape.  

Turn to the front of the device and zoom in on the lens. You must rotate and slide with the model until you see 3 groups of 2 symbols.  

If you have done well, the bottle with the purple liquid will stand up. Make a note of which symbols belong together. Zoom out and turn to the back, zoom in on the bottle and take the bottle.  

Zoom out and go to the microscope, zoom in on the back of the microscope. Put the bottle with the purple liquid in the rack and turn the rack, the purple bottle is now in front of the microscope.  

Zoom out and go to the top of the microscope and zoom in on the lens. Turn the outer ring to focus the image, you will see 3 different figures.  

8 tetrahedrons (4 planes), 2 octahedrons (8 planes) and 4 dodecahedrons (12 planes). When the image is sharp you get a look at the foot of the microscope, you see a drawer sliding open.

Zoom out and zoom in on the drawer, take the golden handle that lies in it.  

Zoom out to the stairs and go down, stay at the bottom of the stairs and pull the lens up. Look along the wall to the barrel behind pipe 1, you can see the drawing of a dodecahedron there.  

Then turn to the boiler and zoom in, you will see a slot in the middle with a holder for a handle on the right. Drag the lever towards it and slide it to the left, this side will open.  

Above you have to roll the reels to get a number at the bottom, but which number. Think of what you saw in the microscope at the purple bottle.

You have just seen that the dodecahedron belongs to pipe 1, at the bottle with the green liquid you only saw 4-surfaces (tetrahedron).

   The green liquid came from pipe 3, which belongs to the tetrahedron.  

For pipe 2, only the octahedron remains. The number you have to make is 4-2-8. I do not know if there are more ways to make this number, but this works:

Turn the upper red button until next to it you see: -- -- 2

Turn the middle red button until next to it you see: 2 2 3

Turn the bottom red button until next to it you see: 2 --  3  

Now at the bottom is 4-2-8, zoom out and zoom in on the bottom, you have to put the right symbols at the pipes.

Take a look at your note of the symbols on the model of the flying machine and put the symbols in their place.  

The side slides shut and you turn to the left, the machine here is now active. Turn right and look at the pressure gauge, it is now at zero but must go to full.

Pull the lever a number of times to increase the pressure.  

Turn back to the 6 lighters, in which order should you light it? That is just trying but this is the order. Number the lighters from left to right 1 to 6.

To light them, pull the red handle in front of them. If you do it in the wrong order, they will go out again.

Re-pressurize and start from the beginning. See what happens when a lighter comes on, fire goes up through a pipe and a ball starts to spin.  

A whole construction will run along. First 5 and then 3, then 4 but it falls off. You have lost this lighter.  

Turn back to the manometer and put it back on pressure. Then pull the red lever at 5 and 3 again, zoom out and go up.  

On the other side there is a box in front of the window, go there, there you will find a spare lighter.

This cabinet is connected to the machine below, if you do not light 5 and 3 again then this box is closed.

Take the lighter and go down again.

Drag the lighter to position 4 and tighten the lighter, then pull the red lever.  

Then pull the red lever at 1, 2 and last at lighter 6. The rotating parts of the time machine work, but something has to be done.  

Zoom out and turn to the fence. Go upstairs and to the box on the other side, there is now a big handle in the box.  

Take this handle and zoom out to the stairs, turn around and look at the remainder of a device. Pull down your time lens, you see white traces just like in the library.  

Click on the white tracks and you will get a figure to draw, do that. Then slide the button to the left and you will see how things should be divided.

The distribution must be L = 3, M = 4 and R = 5  

Go out of the time lens and turn to the left, there you will see a device that is very similar to what you have just seen. Go to that device, you see 3 rows of boxes, L, R and M.

With the button O at the bottom you select the row where you get the blue squares.

With the top button B you select the row where the blue boxes goes in, on the left you see a holder for the lever.

Drag the lever towards it, button B and O are now at the middle row.  

Slide B to the left and pull handle H down, the boxes are now moved. Now slide O to the right and pull H down, O now to the left and B to the middle. Pull H down.

Now O to the middle and B to the right, pull H down.  

You now see a lever going up, now pull it towards you and........

....... then look at what happens next.

End movie
