Focus Description:

There are three identical bottomless nesting dolls on the table. Under one of them there is another nesting doll, under the other two there is nothing. Shuffle three nesting dolls on the table and invite the audience to guess which one is under the nesting doll. No matter what nesting doll the audience points to, it will always be empty under it.

The matryoshka will appear either under one or another nesting doll, but not under the one that the audience will point to.

Focus secret:

Under each matryoshka there is exactly the same bottomless nesting doll. If you pick up any matryoshka together with the nesting doll inside, and show them from the bottom, it will seem that this is one empty nesting doll.

In order for the inner matryoshka to appear on the table, you just need to remove the outer nesting doll, and leave the inner one on the table. If both nesting dolls are carved from wood, then they should have a through hole on top for the index finger, so that with its help either leave the nesting doll on the table, or raise it and show that there is nothing inside.

Nesting dolls made of papier-mâché do not require holes: they can be controlled by slightly squeezing or releasing the body of the outer nesting doll. Unlike real nesting dolls, which have a conical bottom, demonstration nesting dolls should be cylindrical in shape so that the inner nesting doll easily comes out of the outer one and easily enters it.

For visual contrast, it is desirable that the coloring of the inner nesting dolls differs from the outer ones. If, for example, the body of the outer matryoshkas will be light, then the case of the inner ones should be dark, etc.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Global warming asymmetry 07.10.2020

New research shows that stronger nighttime warming is more common worldwide than stronger daytime warming. Scientists at the University of Exeter studied warming from 1983 to 2017 and found a difference in average annual temperature of more than 0,25°C between daytime and nighttime warming over more than half of the land surface.

Days warmed faster in some places and nights warmed faster in others, but the total area of disproportionate warming at night was twice that.

The "warming asymmetry" was mainly due to changes in cloud levels. Increased cloud cover cools the surface during the day and retains heat at night, resulting in even more warming at night.

"Warming asymmetries could have major implications for the natural world," said lead author Dr Daniel Cox of the Institute for Environment and Sustainability at Exeter's Penryn campus in Cornwall.

Stronger nighttime warming is associated with a wetter climate, and this has been shown to have important implications for plant growth and how species such as insects and mammals interact.

Greater diurnal warming is associated with drier conditions coupled with higher levels of overall warming, which increases species vulnerability to heat stress and dehydration.

"Species that are active only at night or during the day will be especially affected," the scientists say.
