Instructions:

Light enters the camera’s interior through a small opening in the door. Observe the projection on the screen. How does the image change if the opening is narrowed? What happens if a lens is held in front of it?

Enter the camera and shut the door. How much time do your eyes need to adjust to the light and recognize something? Observe the projection on the screen

• Open the sliding aperture and then close it slowly. What happens?
• How does the image alter when you narrow the opening?
• Open the door and examine the premises. Close the door and look at the projection. Is the projection mirrored or flipped?

The word ‘camera’ derived from the Latin word ‘camera obscura’, meaning ‘dark chamber’. The functional principle of the pinhole camera was already known in the antiquity and was described in detail in the 10th century by Abu Ali al-Hasan ibn al-Haitham (965-1039/1040). The Arab mathematician, known in Europe as ‘Alhazen’, rejected the previously known concept of ‘the ray of vision’, which could explain mirror phenomena but not the observations of the camera obscura.  

The word camera comes from the latin phrase camera obscura, meaning “dark room”. The principle of the pinhole camera was known in Antiquity and was described exhaustively in the 10th centurz by Abu Ali al-Hasan ibn al-Haitham (956-1039/1040), latinized as Alhazen. The Arab mathematician rejected the then-prevelant idea of a beam of vision, which could explain reflection-based phenomena, but not what was observed in the camera obscura.

General Instructions:

• Can you stand straight? Check yourself and the others, in what angle are you standing to the floor?
• Walk slowly in a circle. Pay attention to how it feels! Is it the same that your eyes see?

Marble scale:

• Adjust the wooden channel so it is horizontal. To see if you are correct, you can place a marble on it. If the wooden channel really is horizontal, the marble should not move much. 

Perpendicular pendulum:

• As soon as the pendulum is released from its anchor, it will point vertically downwards. 
• Using a wooden marble, give a guess as to which one of the boxes the tip of the pendulum will point to.

Marble Track:

• Where does the marble have to start to be able to traverse the whole marble track?

Not only in Jena can you find leaning houses. In Ulm, a half-timbered house from the 14th century advertises itself as the “most crooked hotel in the world”. The Oberhafen canteen in Hamburg, the old fulling mill in Wernigerode and the “leaning houses” in Idstein and Großbottwar are also very crooked.

Instruction:

Two people stand in the opposite corner of the room. The others watch from outside the house. Which of the two people inside the house seem taller?
• Examine the shape of the room. What angles and surfaces can you see?
• Which of the two people is standing closer to you? Which one looks bigger?
This construction is based on the work of the American optician Adelbert Ames who probably built on Hermann Helmholtz’s ideas. This optical illusion finds a very practical use in the film industry; In the ‘Lord of the Rings’ films, the scenes involving hobbits and humans where shot in trapeze-shaped, distorted sets to create the illusion of difference in size.

Instructions:

On this bike, you too can become a tightrope artist.

• How heavy do you think the balancing arm is? How long is it?
• Where is the centre of gravity of a normal bike?
• Where is it on the tightrope bike?

Sadly, the tightrope bike is out of service in the winter. Since the steel rope contracts in low temperatures, it is necessary to slacken it come nightly frost.

Instructions:

Place your ear on one end of the spiral and speak into the other end slowly and clearly.

• Say short words loudly
• How much time do you think passes between speaking a word and hearing it?
• How long do you think the listening spiral is?

Small male frogs that are unable to find a mate due to their small, quiet sound sacs have a better chance at lower temperatures. Cold air conducts sound better, so the sound bubble sounds louder at low temperatures, and the males are more likely to be “heard.”

Instructions:

A round track – But is the chair driving on it in it’s initial position after one round?

• How many rails is the track made up of?

• In what position would you arrive after one round, if the chair could not turn?

The stainless steel construction has a different angle in every segment, which could not be calculated before the build. Therefore, a wooden model had to be built to scale to discern the correct measurements required.

Instructions:

Take place opposite of each other and speak towards the wall.

• Can you understand your partner better when he is facing towards you while speaking or when he whispers sideways, towards the wall?

• While speaking loudly, move towards the centre of the whispershell. What do you hear? What do the others hear?

One person takes position in the centre and tries to either speak to the others or listen to their conversation.

• Standing in the middle, say a few words. How does your voice sound to you? How does it sound to the others?
• Do you have an idea as to why the dome is open at the top?

Instructions:

• How many people have to stand on the shorter end of seesaw in order to lift the longer end?
• Are you able to balance the beam out?
• What do you think: How heavy is the beam?
• How many more people must stand on the short end in order to lift a person standing on the long end?

„Bürger in Bewegung“ (Moving Citizens) is the title of the planned monument to the reunification of Germany in Berlin. The
design by Stuttgart architects Milla and Partner and the Berlin-based artist Sasha Waltz comprises of a dish set up so that it
can be shifted to the side by a sufficient amount of people.

?? English instruction:

A long, heavy pendulum is set in motion. Stay a while, calmly observing the patterns it creates.

• Observe the movements of the pendulum, how do they change over time?

• How long does it take until the pendulum rests once more?

• Which basic shape can you recognize in the patterns in the sand?

In 1851, the French physicist Jean Bernard Léon Foucault (1819-1868) proved that the earth rotates using a pendulum of 67m length. In 1997, Imaginata repeated the experiment in the then-gutted ‘Uni-tower’ in Jena, earning a mention in the Guiness book of records. Today, the pendulum draws it’s patterns on the Imaginata’s own premises.
