Portable interactive exhibits
Each protective case contains one exhibit. Setup may require a few easy steps. The open lid doubles as holder for A3 instruction panels.
Visitors are challenged to arrange eight shapes to form a rectangle and
at the same time consider that no two pieces of the same color are next
to each other. This is a simplified version of Stomachion, probably created by Archimdes of Syracuse 2200 years ago.

Visitors solve the following puzzle: „You have a crate that is 6 holes
wide by 4 holes deep. You have 18 bottles. You have to put an even
number of bottles into every row and column.“
€1,088.00*
Visitors take one of the transparent tubes and gently mix the pebbles
inside, shake the tube vigorously and compare the resulting mixture to
the other tubes. Depending on the mixture of objects, they notice that
the largest and probably heaviest particles rise to the top.
€3,408.00*
Visitors squeeze the bottle and observe the „diver“ inside the bottle
sink to the bottom. On closer examination, visitors see the air bubble
inside the diver glass tube being squeezed smaller before it sinks.

Visitors are challenged to solve the handshaking problem: „In a room of n
people, how many different handshakes are possible?“. They find a
graphical solution of all combinations using rubber bands. They also can
test the handshaking lemma: „In a party of people some of whom shake hands, the number of people who shake an odd number of other people's hands is even.“
€1,488.00*
Visitors adjust the brightness of three overlapping LED disks - each
colored red, green and blue. In the intersections of two or tree disks
the colors are mixed and the addition of colors is visible. When each
color is at the same level of brightness, the center appears white.
€4,288.00*
Visitors touch different materials with two electrodes. If they touch a
conductor, a signal sounds and they can read the current on a meter. One
material is wire with a high resistance, so visitors can read the
changes in current.
€3,648.00*
Visitors find out how many possible floor patterns are possible when
tiling „rooms“ that are 1 „tile-lengths“ wide and between 1 to 5
„tile-widths“ long. The solution should be: 1, 2, 3, 5, 8 – which looks
like a part of the Fibonacci series.
€1,248.00*
Visitors try to draw simple shapes or write their own name to look
„normal“ in a cylindrical mirror. Even with the guiding lines on the
drawing board, it is very difficult do draw a straight line, circles are
even more challenging.
€2,528.00*
Visitors are challenged to fit all the dominoes into the upper recessed
area so that the dots in the vertical columns add up to 2 and the
dominoes in the bottom row add up to 8.
€1,568.00*
Visitors use transparent miniature tanks to observe how different
liquids like water and oil compare to granular materials like sand when
drained. Everyone knows running water, the oil stream looks different
and sand will flow until the remaining cone reaches the angle of repose.
€3,808.00*
Visitors press the diaphragm of the device at their necks directly on
the wind tube and speak with a hoarse voice. The vibration of the vocal
folds are picked up, amplified and a „robotlike“ voice quality is
produced.
€5,728.00*
Visitors use a small periscope to find the hidden object in the scenery. As a game, one visitor arranges the covers and hides the toy figure out of direct line of sight, the other uses his optical tricks to look around things.
€3,008.00*
Visitors press their hands onto a temperature sensitive film and see
their hand prints disappear at different speeds, depending on the
material under the film. Heat is conducted into the environment at
different rates. Electrical conductors like copper are also good heat
conductors.
€3,488.00*
Visitors create a voltaic cell by poking one zinc nail and one copper
wire into each end of a lemon. The zinc nail will become the „−“ or
negative terminal of the battery (also called the anode) and the copper
wire will become the „+“ or positive terminal of the battery (also
called the cathode).
€2,768.00*
Visitors are challenged to put the matchsticks together to make an original figure. There are many puzzles to solve.
€2,288.00*
Visitors use a metal detector to analyze the provided test pieces or
their own objects. The detector produces a magnetic field that is
distorted by metallic objects, the electric signal is converted into
sound: the closer the detector is to metal, the louder the sound.
€3,328.00*
Visitors try and trace the outline of a maze pattern while looking into a
mirror and forcing their hand to follow the mirror image pattern. A
tone beeps when the pen moves outside of the pattern’s outline. This is a
challenge that disturb the lateralization of brain functions.
€3,488.00*
Visitors play with various objects, made from clear plastics, under a viewer and observe striking colors and photoelasticity effects when they move and bend the objects. The polarized viewer on top only allow light vibrating horizontally to pass through, the light box emits vertically polarized light.
€3,968.00*
Visitors try to fit together five pieces either to make the one big
square or the other two squares which are drawn around the triangle.
They find out that this only works for right triangles.
€1,568.00*
Visitors attach tubes of different length at the flanges of fixed pipe
elbows and create sounds by tapping the ends with rubber „flip-flops“.
The shorter the tube, the higher the pitch of the sound produced.
€2,688.00*
Visitors fit the supplied blocks together to make an arch. When their construction is finished, they put a one kilogram weight on top of the keystone to test the arches strength. Arches are stable without glue or screws since the 2nd millennium BC.
€2,928.00*
Visitors test the relationship between grain size and hole size at different transparent cylinders filled with a mixture of materials. Only when the right mesh size is chosen, a sieve can separate different materials
€5,248.00*
Visitors speak or blow a whistle into a microphone and observe the
resulting curve on a screen. The waveform changes with volume, distance
to the microphone and the pitch of the sounds.
