The video, taken in a kitchen, opens with footage of a bottle of water being poured into a glass A lot of users have, however, pointed out that the video appears to have been edited. One user wrote: 'If know one has realised yet, notice how the glass loses its shadow in the process of putting down the bottle. That is where he did the editing.' Speaking to FEMAIL about the video, Eoin Smith, an award-winning magician from Aberdeen, said: 'There has been a lot of speculation online about this video, with people debating whether it is incredible sleight of hand or clever camera trickery.'

'In recent years, magicians have found a new home on YouTube, Vine and Instagram, and this follows a long tradition of magic on film - some of the earliest pioneers of film-making were magicians, like Georges Méliès.' • An earlier version of this article wrongly credited YouTube user KUKR as the creator of the video. We are happy to clarify that the creator is in fact Avery Monsen. Various kinds of mirages in one location taken over the course of six minutes, not shown in temporal order. The uppermost inset frame shows an inferior mirage of the. The second inset frame is the Farallon Islands with a on the left-hand side. The two lower frames and the main frame all show superior mirages of the Farallon Islands. In these three frames, the superior mirages evolve from a 3-image mirage (an inverted image between two erect ones) to a 5-image mirage, and then back to a 2-image mirage. Such a display is consistent with a. All frames but the upper one were photographed from about 50–70 feet above sea level. The upper frame was photographed from sea level. A mirage is a naturally occurring in which light rays bend to produce a displaced image of distant objects or the sky. The word comes to English via the mirage, from the mirari, meaning 'to look at, to wonder at'. This is the same root as for ' and 'to admire'. Mirages can be categorized as 'inferior' (meaning lower), 'superior' (meaning higher) and ', one kind of superior mirage consisting of a series of unusually elaborate, vertically stacked images, which form one rapidly changing mirage. In contrast to a, a mirage is a real optical phenomenon that can be captured on camera, since light rays are actually refracted to form the false image at the observer's location. What the image appears to represent, however, is determined by the interpretive faculties of the human mind. For example, inferior images on land are very easily mistaken for the reflections from a small body of water. An inferior mirage on the in spring For exhausted travelers in the, an inferior mirage may appear to be a lake of water in the distance. An inferior mirage is called 'inferior' because the mirage is located under the real object. The real object in an inferior mirage is the (blue) sky or any distant (therefore bluish) object in that same direction. The mirage causes the observer to see a bright and bluish patch on the ground in the distance. Light rays coming from a particular distant object all travel through nearly the same air layers and all are bent over about the same amount. Therefore, rays coming from the top of the object will arrive lower than those from the bottom. The image usually is upside down, enhancing the illusion that the sky image seen in the distance is really a water or oil puddle acting as a mirror. Inferior images are not stable. Hot air rises, and cooler air (being more ) descends, so the layers will mix, giving rise to turbulence. The image will be distorted accordingly. It may be vibrating; it may be vertically extended (towering) or horizontally extended (stooping). If there are several temperature layers, several mirages may mix, perhaps causing double images. In any case, mirages are usually not larger than about half a degree high (same apparent size as the sun and moon) and from objects only a few kilometers away. Heat haze [ ]. Heat haze caused by jet engine exhaust Heat haze, also called heat shimmer, refers to the inferior mirage experienced when viewing objects through a layer of heated air; for example, viewing objects across hot or through the exhaust gases produced. When appearing on roads due to the hot asphalt, it is often referred to as a highway mirage. Causes the temperature of the air to vary, and the variation between the hot air at the surface of the road and the denser cool air above it creates a in the refractive index of the air. This produces a blurred shimmering effect, which affects the ability to resolve objects, the effect being increased when the image is magnified through a. A hot-road mirage, 'fake water' on the road, the most common example of an inferior mirage Light from the at a shallow angle to the road is by the index gradient, making it appear as if the sky is reflected by the road's surface. The mind interprets this as a pool of water on the road, since water also reflects the sky. The illusion fades as one gets closer. On roads it may look as if water, or even oil, has been spilled. These kinds of inferior mirages are often called 'desert mirages' or 'highway mirages'. Both sand and tarmac can become very hot when exposed to the sun, easily being more than 10 °C hotter than the air one meter above, enough to create conditions suitable for the formation of the mirage. Heat haze is not related to the atmospheric phenomenon of. An artificial mirage, using sugar solutions to simulate the inversion layers. A cat is seen looking through a glass, which has three layers of solution, with decreasing from bottom to top. The cat appears in multiple images. This simulates an atmosphere with two inversion layers. A superior mirage occurs when the air below the line of sight is colder than the air above it. This unusual arrangement is called a, since warm air above cold air is the opposite of the normal temperature gradient of the atmosphere. Passing through the temperature inversion, the light rays are bent down, and so the image appears above the true object, hence the name superior. Superior mirages are in general less common than inferior mirages, but, when they do occur, they tend to be more stable, as cold air has no tendency to move up and warm air has no tendency to move down. Superior mirages are quite common in, especially over large sheets of ice that have a uniform low temperature. Superior mirages also occur at more moderate latitudes, although in those cases they are weaker and tend to be less smooth and stable. For example, a distant shoreline may appear to tower and look higher (and, thus, perhaps closer) than it really is. Because of the turbulence, there appear to be dancing spikes and towers. This type of mirage is also called the or hafgerdingar in the. A superior mirage can be right-side up or upside down, depending on the distance of the true object and the temperature gradient. Often the image appears as a distorted mixture of up and down parts. Superior mirages can have a striking effect due to the Earth's curvature. Were the Earth flat, light rays that bend down would soon hit the ground and only nearby objects would be affected. Since Earth is round, if their downward bending curve is about the same as the, light rays can travel large distances, perhaps from beyond the horizon. This was observed and documented for the first time in 1596, when a ship under the command of in search of the became stuck in the ice. The crew was forced to endure the polar winter there. They saw their midwinter night come to an end with the rise of a distorted Sun about two weeks earlier than expected. It was not until the 20th century that science could explain the reason: the real Sun had still been below the horizon, but its light rays followed the curvature of the Earth. This effect is often called a. For every 111.12 kilometres (69.05 mi) the light rays can travel parallel to the Earth's surface, the Sun will appear 1° higher on the horizon. The inversion layer must have just the right temperature gradient over the whole distance to make this possible. In the same way, ships that are in reality so far away that they should not be visible above the geometric horizon may appear on the horizon or even above the horizon as superior mirages. This may explain some stories about flying ships or coastal cities in the sky, as described by some polar explorers. These are examples of so-called Arctic mirages, or hillingar in Icelandic. If the vertical temperature gradient is +12.9 °C per 100 meters (where the positive sign means temperature gets hotter as one goes higher) then horizontal light rays will just follow the curvature of the Earth, and the horizon will appear flat. If the gradient is less (as it almost always is) the rays are not bent enough and get lost in space, which is the normal situation of a spherical, convex 'horizon'. In some situations, distant objects can get with no mirage involved. Fata Morgana [ ]. Main article: A Fata Morgana, the name of which comes from the Italian translation of, the fairy shapeshifting half-sister of King Arthur, is a very complex superior mirage. It appears with alternations of compressed and stretched zones, erect images, and inverted images. A Fata Morgana is also a fast-changing mirage. Fata Morgana mirages are most common in, especially over large sheets of ice with a uniform low temperature, but they can be observed almost anywhere. In polar regions, a Fata Morgana may be observed on cold days; in desert areas and over oceans and lakes, a Fata Morgana may be observed on hot days. For a Fata Morgana, has to be strong enough that light rays' curvatures within the inversion are stronger than the curvature of the. [ ] The rays will bend and create. An observer needs to be within an to be able to see a Fata Morgana. Fata Morgana mirages may be observed from any within the, including from mountaintops or airplanes. A Fata Morgana can go from superior to inferior mirage and back within a few seconds, depending on the constantly changing conditions of the atmosphere. Sixteen frames of the mirage of the, which cannot be seen from sea level at all under normal conditions because they are located below the, were photographed on the same day. The first fourteen frames have elements of a Fata Morgana display—alternations of compressed and stretched zones. The last two frames were photographed a few hours later around. The air was cooler while the ocean was probably a little bit warmer, which made lower. The mirage was still present, but it was not as complex as it had been a few hours before sunset, and it corresponded no longer to a Fata Morgana but rather to a superior mirage display. Distortions of image and bending of light can produce spectacular effects. In his book Pursuit: The Chase and Sinking of the 'Bismarck', the author Ludovic Kennedy describes an incident that allegedly took place below the Denmark Strait during 1941, following the sinking of the Hood. The, while pursued by the British cruisers Norfolk and Suffolk, passed out of sight into a sea mist. Within a matter of seconds, the ship re-appeared steaming toward the British ships at high speed. In alarm the cruisers separated, anticipating an imminent attack, and observers from both ships watched in astonishment as the German battleship fluttered, grew indistinct and faded away. Radar watch during these events indicated that the Bismarck had in fact made no changes of course. Night-time mirages [ ] The conditions for producing a mirage can take place at night. Under most conditions, these are not observed. However, under some circumstances lights from moving vehicles, aircraft, ships, buildings, etc. Can be observed at night, even though, as with a daytime mirage, they would not be observable. This includes the mirage of astronomical objects. Mirage of astronomical objects [ ]. 10 Amazing Optical Illusions: When the arrow is moved to a particular distance behind the glass, it looks like it reversed itself. When light passes from one material to another, it can bend or refract. In the experiment that you just completed, light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow. Anytime that light passes from one medium, or material, into another, it refracts. Just because light bends when it travels through different materials, doesn't explain why the arrow reverses itself. To explain this, you must think about the glass of water as if it is a magnifying glass. When light goes through a magnifying glass the light bends toward the center. Where the light all comes together is called the focal point, but beyond the focal point the image appears to reverse because the light rays that were bent pass each other and the light that was on the right side is now on the left and the left on the right, which makes the arrow appear to be reversed.
