Who is the Laboratorium for?
For curious primary and secondary school students, parents and teachers — and for adults who finally want to understand how an engine, a lens or a black hole works.
Interactive experiments
Laboratorium: science you can touch
Drag magnets, launch planets, look inside an engine cylinder and split light. Every experiment computes real physics, comes with an explanation and formulas, and has challenges it checks by itself.

Challenges in every experiment
Tasks the page checks by itself: set the lens so the image is twice as large, reach a 400 km orbit, find the bubble with a period of 13.
Badges and explorer paths
Paths link experiments into stories, such as “From a candle to a galaxy” or “How an engine works”. Progress is saved only in this browser.
Question of the day
A short question every day, with an explanation and a link to the experiment where you can check it yourself.
Real physics, nothing to install
The simulations solve the real equations, and every simplification is explained. It runs in the browser on a computer or phone, with no account and no ads.
Sections and sample experiments
The experiments are grouped into sections. New ones keep arriving, and those still being built are marked “Under construction” in the Laboratorium.
Physics
Motion and forces from Newton’s laws to a crash test, oscillations and resonance, materials and structures with a bridge designer, a magnetic field with iron filings, N-body gravity and a Voyager-style gravity assist, energy on a ramp, the double pendulum and chaos, a gas of molecules, Archimedes’ principle, electric circuits, radioactivity with Marie Skłodowska-Curie’s discoveries, relativity with the twin paradox, the quantum world with the double slit and the Hamiltonian, elementary particles with a hunt for the Higgs boson, charges and lightning with a live thunderstorm, and heat and the heat pump in thermal vision.
Light
An optical bench with real ray tracing, lenses and the eye, waves refracting at a boundary, spectra that reveal what stars are made of, and the laser — from stimulated emission to the blue diode and Blu-ray.
Sound and waves
A spectrogram from your microphone, Fourier series drawn with epicycles, the Doppler effect, a guitar string and wave interference on water.
Technology
Four-stroke and two-stroke engines, the jet engine together with the scramjet, a steam engine with a Watt governor, the electric motor, a wing in a wind tunnel, power plants from coal to thorium and fusion with a game of keeping the grid at 50 Hz, a computer from the transistor to your own processor, and the history of clocks from a sundial’s shadow to the atomic clock and pulsars.
Space
The planets where they are today, the seasons and white nights, the atmosphere from clouds to auroras, Moon phases, eclipses and the saros, galaxies and their collisions, a black hole and gravitational waves, the scale from the Planck length to the edge of the observable universe, a rocket flight to orbit and a Hohmann transfer, and spacecraft propulsion: ion drives, solar sails, nuclear rockets and braking in a vacuum.
Biology, chemistry and math
Animal and plant cells with mitosis, the nerve impulse in a neuron, the nervous system with a reaction test, the heart with an ECG, the lungs and a spirometer, blood and blood groups, the lymphatic system and immunity, the kidneys and blood-pressure control, the liver, the eye and color vision, the DNA double helix, live natural selection and genetic drift, a forest ecosystem with a food web and the Lotka–Volterra equations, 118 elements with data cards and key compounds, 3D molecules with an editor, isomers and equation balancing, acids and bases with the pH scale and titration, batteries and electrochemistry, fire and the candle flame, kitchen chemistry from the Maillard reaction to fermentation, solutions and osmosis, reaction rates with catalysts and enzymes, plastics and polymers with recycling, air and smog, metals from the blast furnace to alloys, crystals from snowflakes to diamond, the Mandelbrot set, the golden ratio, the number π, trigonometry with the unit circle, geometry with animated proofs, solids with their nets, complex numbers with 3D plots, functions from parabolas to logarithms, prime numbers and ciphers from Caesar to RSA, infinity with Hilbert’s hotel, probability with a Galton board and the Monty Hall problem, and the Game of Life.
FAQ: Laboratorium
The most common questions from parents, teachers and the curious.
Do I need to install anything or create an account?
No. Every experiment is a single page in the browser. Badges and completed challenges are saved locally on your device and are never sent anywhere.
Can I use it in class?
Yes. The experiments work well on a projector or for pair work. Challenges and the question of the day help start a discussion, and the explanation panel shows the formulas.
Why does the spectrogram ask for the microphone?
To show your voice or a whistle as a spectrum. The sound is analyzed only in the browser and is never recorded or sent. Instead of the microphone you can use the built-in tone generator.
Is it available in Polish?
Yes — the Laboratorium was written in Polish, and the PL | EN switch next to “← Laboratorium” changes the language on every page. Progress and badges are shared between both versions. Some examples come from Poland, such as the Polish electricity grid, Kraków smog or the Polish Lotto.
