Copernicus at the Picnic


Experiment with exhibits borrowed for the Picnic straight from the Copernicus Science Centre.
Sensory memory lasts half a second maximum. According to some researchers, it stores 99% of information received from sensory stimuli. Do you have a better memory than a chimpanzee? Find out by trying to repeat a sequence of numbers.
Boiling hot or freezing cold? Information about warmth and cold is received by the same skin receptors. Our exhibit consists of two spirals – one of them gives heat, the other cools. By touching them with your hand, you will feel warmth or cold. In the exhibit’s central part the spirals are heavily intertwined so our thermoreceptors receive conflicting signals and it’s hard to say whether we actually feel warm or cold.
Brain is our personal super-computer that hasn’t revealed all its secrets yet. That’s why it’s worth taking a closer look at it. Assemble an anatomic model of the brain and learn about the functions of its different components.
120/80 is the model result of an adult’s blood pressure. And how about your heart? We invite you to a mini-workshop during which we’ll measure our blood pressure, learn about the anatomy of the heart and listen to it. We’ll find out that slamming doors sound almost identical to closing heart valves. We’ll also look at the evolution of a statoscope, and the youngest participants will make their own device with the use of a funnel and a tube.


For one day, our maker space will move from the Copernicus Science Centre to the Picnic, and keep our brains active and busy.
A piece of wetsuit, wire, string, a few screws, magnets and rubber bands. Take the challenge and use these parts to create the longest, fastest and most twisted route for a small ball. Don’t give up easily! Remember that such “analogue” activities stimulate your brain more than complicated tasks solved with the use of computer.


Being in a lab is a great opportunity to experience new technologies.
If you can’t sneeze “on request”, we’ll make you do so! And then we’ll record your sneeze with a fast camera (which registers from 1,000 to 10,000 frames per second). This will allow us to see what exactly happens to the nose, mouth and eyes during a sneeze.
Find out how development of technology is beneficial for our health – see and try prosthetic hands made on a 3D printer. They are very easy to make, functional and cheap.


The Planetarium Team will take a lot of specialised equipment to the Picnic!
Together with the youngest Picnickers we’ll build a Solar System and learn about mechanisms behind lunar eclipses of our natural satellite. We’ll also find out why we sometimes have a full and other times a new moon.
If you want to conduct your own astronomical observations, a short telescope operation training will come in handy. As the Picnic takes place during the day, we’ll observe… photos of different astronomical objects placed at a large distance from our stand.


Esero Project is about cosmic lessons for all schools – and this time not only for students and teachers.
Check how you look in UV light! Stand in front of a special camera and play in a movie. Before, we’ll put make-up on you – a sun cream with UV filter.
You have the impression of being heavier after winter? Remember that weight is a relevant matter. Our set of re-scaled weighting scales will show your weight on three different planets. You will also have a chance to see how many cosmic “barbells” you can lift.


Find out how much you can learn by researching and experimenting.
We know that water conducts electricity – but which of water’s ingredients exactly? We’ll test it by putting salt on a wet fabric. We’ll also check the hardness of different mineral waters and find out how the level of mineralisation influences washing properties.


Young explorers from all over Poland invite you to experiment together!
“ELEKTRON” YEC from Witulin will introduce us to the world of vitamins. We will learn how to test food for vitamin C and measure its amount in a classic pill.
Among the members of YEC Wicko there are twins. They will prepare a very convincing show of making some “false” cream. The fact that two things look identical doesn’t always mean they are actually the same.
“NUCLEUS” YEC from Kraków will present their hand-grown radishes. We’ll see how these vegetables have grown in acidic, alkaline and neutral soil. How do we feel temperature? We’ll find the answer to this question with the members of “Szperacze” YEC from Korfantów. We’ll also try to find where to feel our pulse best.
“Trzaśnięte próbówki” is another YEC from Korfantów. Its members will create a chemical wound and together we’ll examine artificial blood.
