?? English instruction:

Three mirrors are set up to form a triangle. Who enters must take care to not lose themselves in their own reflections.

• Can you look at yourself from all · sides without moving?

• Raise your right hand. Which of your reflections raise their right hand, which their left?

The Earth Tower shown at Expo 2005 in Japan is thought to be the largest kaleidoscope in the world. Like a normal kaleidoscope, it is triangular – but 47 meters high.

?? English instruction:

• Take one of the wheels out of its slot and hold it in front of your face, so that
you are looking at its black back.
• Now look at the mirror through the uppermost slot with one eye. Spin the
wheel – slowly at first, then faster. First to the right, then to the left.
• What do you see on the disc?
• What do you see in the mirror when you look through the slots in the disc
while it is rotating?
• What happens when the rotation is very slow?
• What do you see when looking directly onto the rotating disc?

?? English instruction:

Plane mirrors and double and triple-sided corner reflectors are mounted on a rotating wheel.

Turn the winch. What happens to your reflection?

• How many reflections can you see?

• Count the rotations of the mirrors, then count the rotations of your reflections.

• In what position must the two sided corner reflector stand in order for your reflection to be upside down?

In the 19th century, the French physicist Jean Bernard Léon Foucault (1819-1868) developed a method to measure the speed of light. Rays of light where reflected between a rotating mirror and a stationary mirror. Focault determined the speed of light by measuring the displacement between the starting point of the rays of light and their subsequent reflection. He measured the speed of light to be 298.000 km/s, rather close to the speed of light in vacuum, 299.792,458 km/s.

?? English instruction:

Two people stand at the edges of the mirror facing each other.
Stand at the edge of the mirror in such a way that one leg is behind and one leg
is in front of the mirror, so that only half of your body can be seen. To keep your
balance you can also hold on to the bar behind the mirror. Now raise your leg in
front of the mirror and watch each other’s mirror image.
Do you have more ideas for similar illusions?
• What do you see? What do the others see?

?? English instruction:

Stand between both mirrors.

Compare this experiment with the mirror tunnel – what are the similarities, what are the differences?

• Look at your mirror images – how often can you see yourself from the front and from behind?

• What would you see if the mirrors were standing parallel to each other?

?? English instruction:

Put the toy blocks into the mirror book and change the angle by adjusting the relative position of the mirrors.

• Look into the Mirror Book. At which angle must the two mirrors be so you can see your face properly?
• Open the book to a right angle and put the toy blocks into it. How many mirror images can you see?
• Now close the book slowly; at which angles can you see complete mirror images?

?? English instruction:

Two mirrors are standing parallel to each other and a small slot allows the view into the infinite.

• Hold your hand into the Mirror Tunnel while you are looking through the slot – how often can you see it?

?? English instruction:

This special kaleidoscope consists of a cube with mirrors on it’s inner walls.

Look into it from above – which symmetries can you see?

What happens to the different reflections when you rotate the cube slowly?

• How many reflections can you see?

• Look at the planes, edges and corners of the cube.

• Which reflections are rotating and which are not?

• Put your head inside the rotating cube.

?? English instruction:

Look in the mirror and draw or write in such a way that you can see and read it
correctly in the mirror.
Try to draw a cross or a house. Master illustrators can even draw the Olympic
rings (remember: three rings on top, two rings below!)
• Start with drawing vertical and horizontal lines – which ones are causing you
more difficulties?
• How long do you need until you can write your name so that you can read it in
the mirror?

What can you see at the centre, where all three mirrors meet?

• How many reflections can you see?

• Move back and forth in front of the triple mirror and look into the centre. What can you see?
