Focus Description:

The performer stands in the middle of the stage, watching his assistants leave. They immediately return, one of them carries a large cylinder covered in velvet with nickel-plated rims on top and bottom, and the second carries out 36 multi-colored balls on a large nose. The performer takes the cylinder, removes the lid lying on it and, showing that the cylinder inside is empty, places balls there one at a time, which are brought to him by an assistant on a tray (Fig. 139). Having placed all the balls in the cylinder, the magician closes the cylinder with a lid and hands it to the assistant.

The assistant, having carried the empty tray backstage, returns and approaches the illusionist, handing him a small transparent glass box he brought out. This box looks like an aquarium. Its sides are fastened with nickel-plated corners, and the bottom and lid are made of nickel-plated metal sheets. The box is transparent, and therefore everyone can see that it is completely empty. The performer shows it to the audience and gives it to the assistant; he, walking to the place, stumbles, and the audience notices that the box, closed at the top and bottom, is completely filled with balls (Fig. 140).

The performer takes the box with balls and shows it to the audience, and at this time the assistant brings out a tray from behind the scenes, onto which the performer pours all the balls from the box; then, going to another assistant, he opens the lid of the cylinder and takes out from it, one after another, two large round cages with live birds (Fig. 141).

Props:

Cylinder with a secret device, covered with velvet.

Glass box with a secret device.

Two large round cages nested one inside the other.

36 folding balls.

36 simple balls.

Ordinary simple tray.

The cylinder (Fig. 179, A) can be made of tin, durable cardboard or two-millimeter plywood. Its length is about 50 cm, diameter is about 25 cm.

We give approximate sizes, leaving you to choose the ones you need. The cylinder has caps at both ends, made in such a way that when they are put on, they can easily be mistaken either for the top of the cylinder or for its bottom. Small, folding handles are attached to the lids. The top of the cylinder is covered with velvet, on top of which two wide metal belts - strips - are placed. If you look from a distance with the lids closed, it may seem that there are four transverse stripes on the cylinder. A cone with a bottom is attached to one side of it (Fig. 179, B). It is made of such a size that two folding cages can easily fit into the cylinder, and 30-36 balls can fit on the opposite side.

The retractable lid and bottom are copper, nickel-plated, and the walls are made of thick glass; Three-millimeter plexiglass is good for this purpose (Fig. 181, 1). The top side of the box, about 25 mm wide, masks a secret drop-down bottom made of nickel-plated copper 2 mm thick (Fig. 181,5). One edge of this bottom inside the box is placed on a small edge A (its position is shown on the left by a dotted line), while the right edge is placed on a movable edge B, which is embedded in the right side of the wide side.

Fig. 181

On the outside it has a small handle (see Fig. 181,5). If edge B is pulled by the handle in the direction of the arrow, the drop-out bottom will jump off the left edge and fall to the bottom of the box thanks to its cutouts at the right end. Edge B is made on a spring, which will immediately move it back. The falling bottom can be seen in Fig. 181,2, which shows a section of a box loaded with balls; the bottom lies on the edges.

Two large cells that fit tightly into one another (Fig. 182) do not require any special explanation. When folded, they easily fit into the cylinder from the cone side.

Folding balls are very easy to make. In Fig. 183, B shows the finished ball, in Fig. 183,A - its internal structure: a spring made of steel wire. The tire is cut out from six pieces of multi-colored fabric. When folded, the ball takes up very little space. The diameter of the balls is 6 cm. All 36 balls are loaded inside the box onto the drop-out bottom lying on the edges. Place them in threes, starting from the right end of the box, under its lid, which you then gradually push in. Place the balls in neat rows. If you now move the handle of edge B, then under the action of the springs of the balls the falling bottom will fall down, and the balls, having straightened out, will occupy the entire box.

Simple balls are the same in appearance as folding ones and can be stuffed with any material: they are placed in a cylinder cone.

The size of the tray must be calculated so that all 36 balls fit on it.

Focus secret:

The secret lies in the design of the cylinder, cages, box and folding balls. Before the session, both cages are put on top of each other, placed in a cylinder and closed with a lid. Its other end is open (the assistant takes it out in this form); on stage the performer places all the balls there, taking them from the tray.

Then the box is charged. The drop-out bottom is placed on the edges and, having slightly pushed the lid in, they begin to lay the folding balls, as mentioned above. Having placed the last row of balls, the lid is pushed back completely. Simple balls are placed on a tray. This is where all preparation for the performance ends.

An assistant takes out the cylinder in a vertical position: the cone hole should be at the top, and the cells at the bottom. At the same time, the assistant discreetly holds the bottom cover, protecting it from opening. When the balls are placed and the cylinder is closed with a lid, the assistant holds the cylinder horizontally, pressing the lid where the balls are with his left hand, and the lid where the cages are with his right hand. In this situation it is easy to deceive the attention of the audience. When it is time to remove the cells, the assistant will simply and easily lift the cylinder up with his right hand, open the lid and remove both cells from the cylinder one by one.

When taking out the box, the assistant must hold it very tightly in his hands so as not to drop it. The index finger rests on the handle of the moving edge. During an imaginary fall, you need to have time to quietly move the handle to the side so that the falling bottom falls down, and the balls, straightened out, fill the entire box.

There are other ways to hold the cylinder and release the falling bottom, but we consider the ones we have described to be the most convenient.

The amateur, of course, is given the full opportunity to change and come up with a different design for the drop-down bottom; this is not so difficult to implement.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

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 ... >>

Martian soil suitable for life 01.12.2017

If humanity ever decides to colonize Mars (and NASA and Elon Musk, for example, have such plans), then we will have to make sure that food can be grown on the Red Planet. This time, a team of scientists from the Wageningen University and Research Center (Netherlands) discovered that earthworms, or earthworms (these creatures make a significant contribution to soil fertility) can live and reproduce in simulated Martian soil.

After the Curiosity rover sent out an analysis of the Martian soil, NASA found that the volcanic soil on the Hawaiian Islands has the closest resemblance to it. Previous studies using this model have had varying success in growing crops. It turned out that potatoes could be grown in special greenhouses on the Red Planet.

Manure is still one of the best fertilizers. Dutch scientists used pig manure in tests: they added it to simulated Martian soil samples and silver quartz sand samples and tried to grow arugula; the researchers then compared the results. To the surprise of scientists, the artificial Martian soil was more "successful".

Then, after the arugula sprouted, the team added another necessary element to some pots - earthworms, or earthworms. These creatures play a key role in revitalizing our planet's soil by digesting dead organic matter and releasing a powerful fertilizer that releases nutrients such as nitrogen and phosphorus. In addition, the worms loosen the soil, allowing air and water to better penetrate into it.

Thus, the tests showed that earthworms and pig manure help grow plants in the simulated Martian soil, and the worms can not only live in it, but also multiply. Such results are encouraging - perhaps one day humanity will be able to grow food on the Red Planet. By the way, the matter, apparently, will not be limited to arugula: for example, scientists reported that they have achieved some success in growing green beans, peas, radishes, tomatoes, potatoes, carrots and watercress. All vegetables (they were tested for the presence of heavy metals and alkaloids) were edible.
