Focus Description:

Take a stack of cards and drop them into the box one at a time. Then lift them up - they form a “house” (Fig. 1).

Focus House from postcards

Focus with a house made of postcards

For the trick, you need a stack of individual postcards and a folding house made from the same postcards. To make the house you will need 18 postcards and adhesive tape. The house consists of 3 completely identical parts, let's call them “blocks”. The block is made as follows.

Four postcards are glued together with small edges. If you open them, you get a square. Two more postcards are glued separately with large edges, and then glued along the perimeter from the inside of the square. These two cards are folded in half upwards. The entire unit folds easily both from left to right and from right to left (Fig. 2). If, while lifting, you open the postcards (due to the two opening downwards), they will maintain a vertical position (Fig. 3).

The whole house consists of 3 floors. The middle one, relative to the other two, is located in the opposite direction, as shown in the figure. The finished blocks are glued together with horizontally placed postcards.

The house is raised using a loop made of fishing line, fixed in the center of the topmost postcard.

The folding house is placed in advance on the bottom of the box. Having lowered individual postcards there, open the entire house upward. Since individual postcards are not visible in the box, it will seem that the postcards have folded into a house by themselves.

Thin cards may not be suitable for demonstrating this trick. For greater strength, instead of one postcard, it is better to use two (as one), gluing them together.

By making a few extra blocks, you can give the house a variety of configurations.

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 ... >>

Cases with a fingerprint sensor for Android devices 09.07.2013

The Hong Kong company FingerQ has released a whole line of cases for Android devices equipped with fingerprint sensors. These sensors provide an additional level of security to smartphones.

The new series of cases was named PrivacQ. To fully use their capabilities, users will also need to install special software on their mobile device. One such application is FingerQ Chat, which allows messaging over an encrypted connection (the application must be installed on both clients). To read the message, you need to swipe your finger in the sensor area. Thus, no one but the user can read his messages.

It is worth noting that if the cover is lost, it will no longer be possible to read previously received messages. On the one hand, this is inconvenient, but if the phone is stolen, then the attacker will not be able to access the protected information. According to the developers, their solution is aimed primarily at business users.

The novelty will be on sale in Hong Kong and the US in July at an estimated price of $40-60.
