how does the drinking duck works?
821351
The water evaporates from the head (Maxwell-Boltzmann distribution)\nEvaporation lowers the temperature of the glass head (heat of vaporization) \nThe temperature drop causes some of the dichloromethane vapor in the head to condense \nThe lower temperature and condensation together cause the pressure to drop in the head (ideal gas law) \nThe pressure differential between the head and base causes the liquid to be pushed up from the base. \nAs liquid flows into the head, the bird becomes top heavy and tips over during its oscillations. \nWhen the bird tips over, the bottom end of the neck tube rises above the surface of the liquid. \nA bubble of vapor rises up the tube through this gap, displacing liquid as it goes \nLiquid flows back to the bottom bulb, and vapor pressure equalizes between the top and bottom bulbs \nThe weight of the liquid in the bottom bulb restores the bird to its vertical position

take the duck over. come back. take the fox over. bring the duck back. take the duck food over. come back. take the duck over.\n\n\nbet you i can solve it!

The proteins and phospholipids float freely in the bilayer.\n\nImagine if you filled a bathtub with water and then dumped a box of those styrofoam peanuts into the tub, pretend these are phospholipids. If you spread them out evenly you'd completely cover the surface of the water. Now take your rubber ducky and pretend it's a protein. You could move the ducky (protein) from one point to the other and the phospholipids will shift out of the way and close any gaps. It works this way because it allows the proteins in membrane to move throughout the surface of the membrane and go where they are needed.

if someone has hiccups,and someone scares that person,then the hiccups go away.so the bartender just wanted to scare the guy so the hiccups can go away instead of drinking water.OH!!!i get it!!then that is when he sayd thank you for getting rid of the hiccups!

You and your best freind go to heaven. At the gates you are told to walk across a field but not to step on any ducks. Your friend starts to cross, but steps on a duck. She (I'm assuming it's a she) is hancuffed to un ugly guy. You cross without stepping on a duck and are handcuffed to A hot guy.\nYou say, "This must be my reward for not stepping on any ducks."\nThen the guy says, "No. I stepped on a duck."\nLOL!!!!!!!!!

Stupid joke but it makes me thirsty....guess I will go drink a bloddy mary. Thanks for the idea!

Best one I know of is gambling. People have a sickness for it. Sell bath-tub rubber ducks at $10.00 a pop. Each bearing their own number. Then at a designated date, drop them all off a bridge into a river. The first duck to pass say a 2-3 mile distance wins a decent token prize. 1st, second & 3rd place. Since it is NON-PROFIT, it should all be legal. Just make sure you have a net at the finish line, so as not to piss someone off about littering & rubber ducks washing everywhere. Don't forget to contact the Media, they love to cover events like this in-light of all the bad news on earth.

Ok, here's how it breaks down.  Water freezes in a unique way compared to most other liquids.  Water freezes in a crystalline latice structure that looks like layers of hexagons.  That's why water expands when it freezes into ice.\n\nNow the second part of the answer is that when you dissolve something like salt or sugar into water, you lower the freezing point of water.  The additives or solutes disturb the way that water freezes by interfering with the water molecules as they try to freeze into their lattice pattern.  This disturbance does not fully prevent water from freezing, it only lowers the freezing point.  As long as it's cold enough, water can still freeze into ice.  By lower the freezing point, the water needs to get colder and colder to be able to turn into ice.  The other side of this is that you can dissolve more things in a hot liquid than a cold liquid.  When you dissolve something to its limit into a liquid, it's called saturating the liquid.  Also, you can dissolve a lot of something in a liquid when it's hot, but then let it cool without disturbing it and it will be a supersaturated solution.\n\nBeer is not only a solution (something dissolved in water), it is a special solutions because of carbonation.  The process of carbonation involves forcing carbon dioxide bubbles through water to  force the carbon dioxide to dissolve in the water or in this case beer.  When they bottle beers, the company is actually supersaturating the beer with carbon dioxide, that's why it always foams a little when opened.\n\nBecause beer has carbon dioxide in it, it's freezing point is lowered so it is less likely to freeze.  When you cool the beer down below freezing with the cap on, the beer will not freeze, but once you open it, you release the carbon dioxide.  As the beer quickly loses the dissolved carbon dioxide, the freezing point for the beer quickly goes up.  Once freezing point gets up to the temperature of the superchilled beer, the beer freezes and turns into a solid.

I just saw one right now, it's flying in the air!\n I think I'll go shoot it for dinner!  \nThanks for the duck!\nBye!

Oh, boy how do i answer this one. I have heard about this and a buddy of mine says it is a blast (pun not intended).\n\nIts definately an adult drinking game with concentual adults. How do i answer this politely?\n\nIt deals with a girl and her friends (mostly gys getting together and drinking heavily.\n\nWhen the game begins the girl stands in the center of a crcle of guys she at this time is wearing high heels, platforms, mary janes etc... two eggs are placed into her shoes. This makes her balance on the balls of her feet.\n\nThe guys get to stare at a girl in a chicken pose (but sticking out)\n\nNow a money tray goes around the guys bet of the girl can make it through each round (12 rounds) without crushing the eggs. While the girl is balancing the guys are individually "keeping themselves occupied" \n\nEach round goes by, she doesnt crush the eggs, she gets to keep the money from the round. If she does break, the lat guy to "make a statement" on her shoes" gets the money.\n\nIt's an adult game.

It used to be thought that if you drank water from a pond that had frogspawn in, a frog could live and hatch out in your throat, which naturally would block your voice. Quacksalvers (that's the traditional English equivalent of snake oil merchants) used to have a scam whereby the quack's stooge used to pretend to be so afflicted; the quack would administer his medicine, lo and behold the stooge would cough up a live frog and "regain his voice", and all the gullible peasants would buy this wonderful cure. For this reason, an obstruction in the throat is known as a "frog".

According to Family Guy (which tends to be on the pulse of the truth for many things...) it is definately something more. Apparently Bert also has a drinking problem and Ernie eats cookies in the bed.\n\nI agree... Rubber Ducky has to be a code word for something else that makes bathtime lots of fun.

It is a physical reaction, not a chemical one. Water molecules strongly attract each other, linking together to form a tight mesh around each bubble of carbon dioxide gas in the soda. In order to form a new bubble, or even to expand a bubble that has already formed, water molecules must push away from each other. It takes extra energy to break this "surface tension." In other words, water "resists" the expansion of bubbles in the soda.\n\nWhen you drop the Mentos into the soda, the gelatin and gum arabic from the dissolving candy break the surface tension. This disrupts the water mesh, so that it takes less work to expand and form new bubbles. Each Mentos candy has thousands of tiny pits all over the surface. These tiny pits are called nucleation sites - perfect places for carbon dioxide bubbles to form. As soon as the Mentos hit the soda, bubbles form all over the surface of the candy. Couple this with the fact that the Mentos candies are heavy and sink to the bottom of the bottle and you've got a double-whammy. When all this gas is released, it literally pushes all of the liquid up and out of the bottle in an incredible soda blast. You can see a similar effect when cooking potatoes or pasta are lowered into a pot of boiling water. The water will sometimes boil over because organic materials that leach out of the cooking potatoes or pasta disrupt the tight mesh of water molecules at the surface of the water, making it easier for bubbles and foam to form. \n\nWhen a scoop of ice cream is added to root beer, the "float" foams over for essentially the same reason. The surface tension of the root beer is lowered by gums and proteins from the melting ice cream, and the CO2 bubbles expand and release easily, creating a beautiful foam on top

The physics is sound, atleast on paper.\n\nbefore you ask the question : how does drink lose its fizz, you should be asking: what is fizz and how is it added to drinks in the first place.\n\nThe process of adding fizz to drinks is called carbonation. Carbon Dioxide (CO2) is bubbled through water/drink under pressure. The gas reacts with water producing a very weak acid called Carbonic acid.\n\nH20 + CO2  --->  H2CO3\n\nCarbonic acid gives the twang or sharp taste to soda pop, beer, sparking mineral water and champagne.\n\nHowever carbonic acid is a very unstable compound and readily decomposes into water and carbon dioxide. The CO2 bubbles out of the liquid, what we observe and call fizz.\n\nWe can prevent the decomposition of carbonic acid, by creating conditions where the compound is stable, hence mantaining the fizz of the drink; viz: \nlow temperature and \nhigh pressure.\n\nRefridgeration helps like some of the other answerers mentioned.\n\nyour device seems to help by re-pressurizing the container, helping the remaining carbonic acid remain stable longer. It should work theortically, but how well it actually does depends on the particular design, on how much pressure it can create and how air-tight it is (it could leak slowly over time and lose the pressure) this would also depend upon how snugly it fits over the neck of bottles of different size. like I said, the design would determine the effectiveness. \n\nyou will only know how good it is from experience :)

I assume you mean how does that work.\n\nMost liquids expand when heated and contract when cooled. The alcohol in thermometer will expand (rise) when heated and contract (fall) when cooled.

If it looks like a duck and quacks like a duck, it probably is a duck.\n\nIt's a scam.
