Focus Description:

Show viewers the black inside of the boxes. It's empty. Take two black cubes measuring 4 x 4 x 4 cm and drop them one by one into the box. Ask viewers:

- How many cubes are in the box? - And after the answer "two" say: - Right. - And take both cubes out of the box again. - And now how many cubes are in the box? - ask the audience. When they tell you that none, answer: - Wrong! - And immediately, one by one, take out 5 or 7 more exactly the same black cubes from the box.

Focus secret:

All the cubes needed to demonstrate the trick are collapsible. Each consists of two identical closed scans, cut out of whatman paper painted black (Fig. a). Both reamers are glued together with their bottoms when one is inserted inside the other. When assembled, they make up a black cube (Fig. b). If both parts of such a cube are folded, the cube will lose its shape (Fig. c).

Focus How many cubes are in the box?

Two assembled cubes are in full view of the audience from the very beginning. The remaining 5 or 7 are folded inside the box against one of its side walls when you show the box "empty". When it's time to take the cubes out of the "empty" box, quickly collect them in the box itself and take them out one by one for the audience to see.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Water found on asteroid Bennu 06.12.2018

The OSIRIS-REx probe, sent in September 2016 to the asteroid Bennu, flew 2,2 million km and arrived at its destination a week ago. It approached the celestial body and moves next to it at a distance of about 10 km. At the rendezvous stage, which lasted from mid-August to early December, the apparatus began scientific observations.

Data obtained with spectrometers showed the presence of molecules containing hydroxyl groups, that is, oxygen and hydrogen atoms bonded together.

The scientists believe these hydroxyl groups are found throughout the asteroid in water-bearing clay minerals, meaning that at some point Bennu's rock material interacted with water. The asteroid itself is too small to hold liquid water, but the findings indicate that liquid water was present for some time on the much larger asteroid from which Bennu broke off.

The researchers note that the data obtained using the OSIRIS-REx cameras confirm Bennu's ground-based telescopic observations and the asteroid model developed in 2013. In turn, the presence of hydrated minerals makes the asteroid Bennu, which appeared during the formation of the solar system, very well suited for the OSIRIS-REx mission to study the composition of primitive volatile and organic substances. The probe is to take soil samples from Bennu and bring them back to Earth in 2023. Scientists hope to obtain from them important information about the history and development of the solar system.
