ENTRANCE AREA - EXHIBIT 1:
The user of the exhibit learns that
sound wave travels through air
at a finite speed. It is a huge pipe
of 150m lenght. The visitor talks at
one end at the same time putting
their ear against the other end.
EXHIBIT 2: SATELLITE
The exhibit user gets acquainted with
how telecommunications satellites can
be used for connection. This is an exhibit
for two people to participate. Sitting
in two chairs at two ends of a huge model
of the globe, the visitors may speak tran-
sferring signals with the use of transmitters
and receivers. The two visitors cannot see
each other, they must use the hanging
satellite model, to which they point
EXHIBIT 4: CURRENTLY
The exhibit user examines whether
and how to shield the electroma-
gnetic waves used in mobile and radio
the experiment the visitor receives
answers. At their disposal they receive
metal lids with various slots, a mobile
phone and a wireless radio.
EXHIBIT 3: THE MOST FAMOUS
CODE IN THE WORLD
The exhibit user, with the use of the tele-
graph key, learns how to transmit messages
with the use of the Morse Code (alphabet),
which is means of communication applied
in certain areas until this day.
EXHIBIT 5: TRADITIONAL
The exhibit users learn how traditional (cable)
telephone works. It is a two people exhibit.
The visitors at two ends of partition wall
construct their telephones connecting
particular items into one with cables. Then,
they are able to talk.
The visitor observes a chart depicting
changes in acoustic pressure in time
function. The chart gets created thanks to
electronic circuit. The visitor talks into the
microphone watching a dynamic chart on
EXHIBIT 7: WHALE TALK
The visitor gets acquainted with infra-sounds
and ultrasounds with the use of their senses.
The infra-sounds can be felt by touching
a vibrating tile or die. The ultrasounds can be
felt by nearing their ear towards trumpet
shaped speaker shaking their head at the
same time. This exhibit shows how some
animals orientate and communicate in space
The visitor uses the acoustic communication
channel constructed with the use of two concave
mirrors - thus learning about the possibilities
of directing sound waves. Two persons exhibit.
The question concerns social, ethical
and legal aspects of wiretapping. The Exhibit
draws attention to capabilities of applying
wiretapping for different purposes. It calls
for reflection upon responding to
questions regarding circumstances where
wiretapping should be allowed.
The visitor has an opportunity to watch
the route of data transferred via Internet.
The user sends their test signal and observes
on the world map through which servers and
at what speed the message has been passed.
The user of the exhibit learns about simple
means of long distance communication app-
lied for many centuries in Africa, southern
parts of Asia and in Oceania. The interaction
consists of listening to 3 recorded rhythms
-messages and own repetition of the rhythm
on hollow wooden drum (produced based
on similar drums used in Nigeria).
* it is possible to install it at the entrance
- e.g. in front of the building
EXHIBIT 12: FLAG CODE
The exhibit user gets acquainted with the essence
of coding based on the example of code applied
until now in sea transport. The visitor reads
the message presented with the use of flags
in exhibition space - above the visitors’ heads.
The user learns about what an optic fibre
is and how it works. Regulating the angle
of the laser beam in the fascinating optical fibre
model they will learn the phenolmenon of total
internal reflection. The user learns that it is possible
to insert light into a transparent rod in such a way
that it does not leave it reflecting multiple times
against its walls within.
– DISRUPTION RESISTANCE
The exhibit user establishes communication
transmitting an electrical signal via copper line
and also sending a similar signal with the use
of the optic fibre. The visitor examines how easy
it is to disrupt the send signals.
The user of the exhibit gets acquainted with
a simple electromagnetic waves detector using
the reaction of waves with gradient ferroma-
gnetic material. Such detectors called coherers
were used at the beginning of radio commu-
nication at the turn of 19th and 20th centuries.
IN SOLID MATTER
The user learns how well sounds i.e. vibrations
propagate in solid matter. The visitor has
at their disposal a long (a few metres long) rod,
at the end of which is positioned an electromagnet-
tic inductor of acoustic vibrations. At the other end,
after placing directly against one’s ear (or indirectly
elbow and ear), those sounds can be perfectly heard.
Additionally, the user may perform an experiment
consisting of hitting the rod with a small hammer
- this will create stronger vibrations that will be
considerably louder and their range of audibility
in the rod may amount to even a few kilometers.
EXHIBIT 17: BULLERBY
This exhibit is for the youngest visitors.
Arranged in the form of two little houses,
it enables to send message with the use
of a box hung on a piece of string. This exhibit
refers to the classical children’s literature
- Astrid Lindgren’s „Six Children of Bullerby”.
