Although light rays travel from a light source in straight lines, it is possible to make them travel along a curved path. Now the thinnest light guides are made of glass, along which light rays travel long distances with various turns.

The simplest light guide can be made quite simply. This will be a stream of water. Light, traveling along such a light guide, encountering a turn, is reflected from the inner surface of the jet, cannot escape, and travels further inside the jet to its very end. Partially, water scatters a small fraction of the light, and therefore in the dark we still see a faintly luminous jet. If the water is slightly whitened with paint, the jet will glow more strongly.

Take a table tennis ball and make three holes in it: for a tap, for a short rubber tube, and against this hole the third is for a light bulb from a flashlight. Insert the light bulb inside the ball with the base outward and attach two wires to it, which then attach to the battery from a flashlight. Secure the ball to the faucet with electrical tape. Lubricate all joints with plasticine. Then wrap the ball with dark matter.

Jet-optical guide

Open the faucet, but not too hard. The jet of water flowing from the tube should, bending, fall not far from the tap. Turn off the light. Connect the wires to the battery. The rays of light from the bulb will pass through the water into the hole from which the water flows out. The light will flow. You will see only its faint glow. The main stream of light goes along the jet, does not break out of it even where it bends.

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 ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

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. ... >>

Possum antidote 19.04.2001

As American biologists have discovered, the marsupial animal opossum, which looks like a rat, is naturally immune to the poisons of various snakes.

From the blood serum of the opossum, a substance called the "neutralization factor of lethal toxins" was isolated, which, in experiments on mice, was able to neutralize lethal doses of various snake venoms, as well as venoms of scorpions and tarantulas. The found substance is a large protein molecule, too complex for mass synthesis.

However, the biochemist B. Lipps was able to break a long molecule into several short segments and found that the resulting peptides - pieces of 10 - 15 amino acids are effective against many poisons of animal, plant and bacterial origin. These peptides can be synthesized artificially and injected into the blood of the poisoned.
