Drinking birdDrinking bird is about to dip its beak in the waterClassificationHeat enginesApplicationToy, Scientific demonstrationTop sourceHeat transferComponentsBulbs, Tube, Axle, SupportInventorMiles v. Sullivan / Chinese CraftspeopleInvented1945 / much earlier than 1920 Drinking birds, also known as insatiable birds, soaking birds, drunken birds, waterbirds or dipping birds, . Sometimes they are mistakenly considered examples of the eternal movement device. The design and materials of the Drinking Bird consists of two glass bulbs connected by a glass tube (the neck of a bird). The tube extends almost all the way into the bottom lamp, and is attached to the top of the lamp, but does not extend into it. The space inside the bird contains liquid, usually stained. The fluid is usually dichloromethane, also known as methylene chloride. Earlier versions contained trichlorofluorethane. Miles W. Sullivan's 1945 patent proposed ether, alcohol, carbon tetrachloride or chloroform. The air is removed from the machine during production, so the space inside the body is filled with steam evaporated from the liquid. The upper light bulb has an attached beak that, along with the head, is covered with felt-like material. The bird is usually decorated with paper eyes, a plastic hat and one or more tail feathers. The whole installation turns to an adjustable crusading machine attached to the neck. Despite the appearance and classification of a drinking bird as a toy, there is a potential danger that thin glass shards in if the light bulb breaks down. Early models were often filled with flammable substances, although the liquid in later versions was non-flammable. Dichloromethane can irritate the skin during contact and lungs when inhaled. It can be dangerous for people with pre-existing heart, liver or nervous system conditions and is a suspected carcinogen. The thermal engine steps Play Media Drinking Bird heat engine, which uses temperature difference to convert thermal energy into a pressure difference in the device, and performs mechanical work. Like all thermal engines, the drinking bird works through a thermodynamic cycle. Starting state It is a bird with a wet head oriented vertically. The process works like this: water evaporates from felt on the head. Evaporation reduces the temperature of the glass head (heat evaporation). The decrease in temperature causes some of the dichloromethan vapors in the head to condense. Lower temperature and condensate together cause a drop in pressure in the head (controlled by state equations). Higher steam pressure in a warmer base pushes the liquid up the neck. As the liquid rises, the bird becomes top heavy and tips over. When the bird envelops, the lower end of the neck tube rises above the surface of the liquid in the lower bulb. The bubble of warm steam rises up the tube through this rupture, displacing the liquid as it goes. The liquid returns to the lower light bulb (the toy is designed in such a way that when it is tipped over on the slope of the neck, it allows). The pressure is aligned between the upper and lower bulbs. The weight of the liquid in the lower bulb restores the bird in an upright position Fluid in the lower bulb is heated by the surrounding air, which at a temperature slightly higher than the temperature of the bird's head. If a glass of water is placed so that the beak dips into it on the descent, the bird will continue to absorb the water and the cycle will continue until there is enough water in the glass to keep the head wet. However, the bird will continue to dip even without a water source, as long as the head is wet, or as long as the temperature difference persists between the head and the body. This differential can be generated without evaporative cooling in the head; for example, a heat source aimed at the lower lamp would create a pressure differential between the top and bottom that would control the engine. The ultimate source of energy is the temperature gradient between the head and the base of the toy; The toy is not an eternal engine. The Physical and Chemical Principles Of Reproduction Media Video Engineering Drinking Bird Drinking Bird is an exhibition of several physical laws and therefore a major chemical and physical education. These include: low-boiling dichloromethane (39.6 degrees Celsius, 103.28 degrees Celsius at standard po 105 Pa pressure - since the pus bird is first evacuated, partially filled and sealed, the pressure and thus the boiling point in the drinking bird will be different), gives the heat propulsion engine the ability to remove the movement from low temperatures. Drinking bird is a thermal motor that works at room temperature. A combined gas law that establishes a proportional relationship between temperature and pressure exerted by gas in constant volume. The ideal gas law, which establishes a proportional link between the amount of gas particles and the pressure in the Volume. The distribution of Maxwell-Boltzmann, which establishes that the molecules in a given space in The temperature varies at the energy level, and therefore can exist in several stages (solid/liquid/gas) at one temperature. The heat of evaporation (or condensation) that establishes that the substances absorb (or suck) heat when the state changes at a constant temperature. Torque and the center of mass. The capillary action braided felt. Wet lamp temperature: The temperature difference between the head and body depends on the relative humidity of the air. Given the difference between the wet and dry temperature of the lamp, it is possible to develop a mathematical expression to calculate the maximum work that can be produced from a given amount of water drunk. This analysis is based on the efficiency of the Carnot thermal engine and psychometric concepts. History By 1760 (or earlier) German artisans was invented so-called pulse hammer (Pulshammer). In 1767 Benjamin Franklin visited Germany, saw a pulse hammer, and in 1768 improved it. Franklin's pulse hammer consisted of two glass light bulbs connected by a U-shaped tube; one of the bulbs was partially filled with water in balance with its steam. Holding a partially filled light bulb in your hand, the water will flow into an empty light bulb. In 1872, Italian physicist and engineer Enrico Bernardi combined three Franklin pipes to build a simple thermal engine that fed on evaporation in the same way as a drunken bird. In 1881, Israel L. Landis received a patent for a similar oscillating engine. A year later (1882) the Lawsuit brothers received a patent for a similar engine. Unlike the birds, the lower tank was heated, and the top tank was simply cooled by the air in this engine. He also used the same principle. The Lawsuit brothers during this time received various patents for the corresponding engine, which is now known as the Minto wheel.

    Sharing Chemistry With The Community A workshop for people who love to share their interest and enthusiasm for doing chemistry with the community! Chem Ed 2013 Conference University of Waterloo Waterloo, Ontario Canada July 27 – August 1 2 Introduction Whether in the classroom or out in the community, when we display chemical phenomena and interact with our audience about it, we are sharing our interest and enthusiasm for doing chemistry. This workshop is all about sharing chemistry – with our students, with the people residing in our communities, and with one another, the community of chemistry educators. We define “chemical demonstration” as any activity that provides the audience with live experiences of chemical phenomena, whether performed by a presenter in front of an audience or hands-on activities in which everyone participates in the doing of chemistry, including laboratory investigations. Demonstrations may address a single concept, a series of concepts, or emphasize a theme. In this workshop, there are activities that address the concepts - Density and Molecular Polarity; a series of concepts – Chemistry of Gases and Chemistry of Light Sensitive Substances; and emphasize a theme – Chemistry of Currency. A live chemical demonstration has the potential to arouse the curiosity of the audience. A skilled presenter can take advantage of this curiosity to interact with the audience, maintain their engagement throughout the presentation, and foster understanding and learning of the relevant chemical concepts. Demonstrations can also be useful in identifying and addressing misconceptions held by the audience. Each of the activities in this workshop has proven to be beneficial, both in the classroom and in the community, helping people to make sense of the chemical phenomena, make connections to their everyday experiences, and construct a deeper understanding of the relevant chemical principles.

    The DRINKING BIRD - A simple heat engine in action The amazing drinking bird, one of the best known 'classical scientific toys', seems to defy scientific laws by demonstrating the impossible - perpetual motion. Or does it? Without any external energy provided - no electricity or winding - it seems to go indefinitely, dipping its head time and again. Patented in 1946 by M V Sullivan (U.S. Patent No 2,402,463) this amazing item has been produced by numerous manufacturers over the years and has gained several identities in the process. Some of these being: Dippy Bird, Magic Bird, Thirsty Bird, Bobbing Bird, Drinking Duck and Dunking Bird. An extract from the first drinking bird patent filed in the USA in 1946. The parts of the Bird Head (hollow glass bulb, partially evacuated) Fuzzy, water-absorbent material Glass tube connecting both bulbs Pivot support Abdomen (hollow glass bulb) Plastic legs Methylene chloride - an industrial paint solvent evaporates easily, has a high vapour pressure and boils at atmospheric pressure at 39.7 °C Paper cup filled with water Copyright Prof Bunsen Science, 2006 How does the Drinking Bird function? 1. The head with its water-absorbent felt, is wetted with water. As the water evaporates the head cools down. The bottom bulb is still at room temperature. 2. Methylene chloride evaporates rapidly at room temperature. As the abdomen bulb is at higher temperature, the vaporization tempo is higher than that in the head. This causes a higher vapour pressure in the abdomen bulb. 3. The greater vapour pressure in the abdomen forces liquid up through the neck to the head.

Transport across a membrane barrier requires energy; therefore, nature has provided a class of molecular machines known as translocases that catalyze protein translocation. Often, these machines contain channels that are too narrow to transport a folded protein; thus, substrate unfolding adds another layer of complexity to the poorly understood transport mechanism. The anthrax toxin system represents a useful model for elucidating the mechanisms of translocation-coupled protein unfolding, both in terms of structure and function. In order to understand the mechanism by which an unfolding machine interacts with its substrate, the X-ray structure of an anthrax protective antigen (PA) oligomer prechannel was solved in complex with the amino-terminal PA-binding domain of the substrate lethal factor (LFN).

  • Solar Drinking Bird
    Solar Drinking Bird Overview: The drinking bird is a classic science toy that dips its head up and down into a glass of water. It’s filled with a liquid called methylene chloride, and the head is covered with red felt that gets wet when it drinks. But how does it work? Is it perpetual motion? We’ll take a look at what’s going on with the bird, why it works, and how we’re going to modify it so it can run on its own without using any water at all! What to Learn: You’ll learn more about the sun than about the bird itself, and especially about the sun’s influence on the Earth, air, and water. Materials drinking bird silver or white spray paint black spray paint razor mug of hot water sunlight or incandescent light Lab Time 1. Take the bird out of its holder, and carefully remove the tail feather, hat, and felt section. Remove any glue with a scraper or hot water, which will allow the glue to loosen and easily peel off. Be careful not to hold the bird by the head, because it is hollow and can break if you grip too tightly! 2. Paint the top (with the peak, from which the hat was removed) either white or silver. Paint the bottom black. Allow it to dry. 3. When the paint is dry, reattach the bird to its stand, and place it in the sun. Adjust the fastening band until the bird is secure, if needed. 4. Liquid is being heated now in the bird, so the bird will begin tipping as water begins moving from the bottom to the top.
