The fairest thing we can experience is the mysterious. It is the fundamental emotion which stands at the cradle of true art and science. He who knows it not and can no longer wonder, no longer feel amazement, is as good as dead, a snuffed-out candle.
Welcome!
Do you disagree with Einstein? Personally, I believe his words perfectly capture the truth about our world: it is wonderful, and we should strive to understand it as deeply as possible. Our reality is shaped by laws and principles, and understanding them allows us to truly comprehend the world around us. This is the essence of science.

Natural sciences may seem daunting, but it all comes down to perspective. While the era of the universal genius like Da Vinci is over due to modern complexity, science remains accessible. Exploring the laws of nature through independent experiments is not only educational but deeply satisfying.
On this website I share free, well-documented descriptions of experiments and observations in chemistry, physics, biology, and other areas of science. The materials are intended for students, teachers, and anyone curious about how the world works. All projects presented here are carried out in my private laboratory, independently of my professional and academic work. This independence gives me the freedom to create and share educational materials openly.
If your school, storage room, garage, or attic contains unused teaching aids (physics, chemistry, biology, electronics), measuring instruments - even very old ones - laboratory glassware, minerals, fossils, or even vintage vacuum tubes from physics classes, I would be happy to give them a second life in educational experiments. An equipment that is slightly damaged or no longer fully functional can sometimes still be useful for demonstrations, repairs, or parts.
Transportation is not a problem; we can always find a practical way to arrange shipping, and if necessary I am happy to cover the cost after making arrangements. I will also gladly help identify unknown equipment and explain how it can be used.
If you think you may have something that could be useful, please feel free to contact me at moze.dzis@gmail.com. I will certainly reply. Every donated item helps expand the possibilities of this laboratory and contributes to freely available materials that inspire curiosity and help others discover the fascinating world of science.
As time allows, I am currently working on translating this website into English to make it more accessible to readers outside the Polish-speaking community. The following sections have been translated so far:
- Astronomy: 81 entries out of 81 available (100%)
- Biology: 31 entries out of 51 available (61%)
- Chemistry: 49 entries out of 102 available (48%)
- Electronics: 14 entries out of 14 available (100%)
- Physics: 30 entries out of 30 available (100%)
The overall progress currently stands at 73% of the total content translated. Where available, the language can be switched by clicking the link at the top of each article.
I would like to express my sincere gratitude to my family and friends for their support and understanding. Their help gives me strength and motivation. I am especially thankful to my brother; without his IT support, this website might never have come to life.
As you know, any knowledge can be used for good or for harm. The experiments, descriptions, and illustrations presented here are intended solely for educational purposes. They should be viewed as an engaging way to broaden your knowledge. However, remember that any experiment performed carelessly or incorrectly may pose a risk to health or life. I strongly caution against attempting experiments that may be misunderstood or not fully clear to the reader for any reason. Remember: you only have one life! If you have any doubts, please contact me first (contact here).
Knowledge gained from the materials on this site must never be used for purposes that violate the law.
Most of the experiments described on this website require no specialized tools or hard-to-obtain materials. I have personally carried out and verified all of them. Where any risk is present, it is clearly indicated and explained in detail.
I also encourage you to explore my publications in scientific and popular science journals.
You may find it useful to review the copyright information for all materials available on this site. It can be found here.
Feel free to experiment :)
