Inventions are discoveries that solve specific problems or needs. The reporter Pere Renom has a lot of containers in front of the window of his bedroom and very often is awakened by the sound of glass thrown at odd hours. Tired of this situation contacts an engineer to develop a soundproof glass container. The prototype […]
Copper, the electric metal
Associated with electricity, copper has helped change the world. Besides being a good conductor some of its compounds are superconductors. In living organisms acts as a transmitter of electrons in many biochemical reactions. Also is part of several blue and green pigments of gothic painting and sometimes can acquire an electric tone.
Three faces of the carbon
What do they have in common the coal, a motorcycle helmet and a diamond? Three sides of the carbon, a chemical element with properties remarkably different depending on how it is organized. Pere Renom built a stack for charcoal. Later attends the size of a diamond and understands why it is so bright. Finally, learns […]
Undressing the laundry
The perfect laundry is a challenge for physics, chemistry and for the reporters of Quèquicom, who learn the best tricks to get an immaculate clothes. How is it possible that the soap used to clean fats, is in fact obtained from fats? What is the difference between soap and detergent? How to use the bleach?
Against the glass
We test the fragility of glass using mallets and Magnum revolver shots with the help of the police. We also show and explain about living organisms protected by glass skeletons: diatoms.
Colors in the sight
Humans are able to distinguish about 10 million colors. This capability has meant that we have incorporated many colors into the culture as symbols of all kinds. However, unlike other perceptions such as taste or hearing, the vision of colors is forgetful. Any way, thousands of pigments are currently available thanks to the modern chemical […]
The lives of iron
Iron is an element used and reused by humans for millennia and has many lives. To learn both the life of iron and the life with iron we will visit a steel mill where hundreds of tons of scrap are recycled every day, by melting to produce steel. We also will go into a mine […]
