Students can use the Drinking Bird Demonstration to refine a device that works with given constraints to convert one form of energy into another form of energy.
Students can use the Drinking Bird Demonstration to conduct an investigation to provide evidence that the transfer of thermal energy when two components of different temperature are combined within a closed system results in a more uniform energy distribution among the components in the system.
Effective for students of all ages. It is important before starting any of the investigations; make sure the bird is at equilibrium. A slight adjustment at the fulcrum or metal clip on the neck up or down is all that is needed until Drinking Bird just balances in a vertical position.
The speed of the bird's dipping cycle changes due to the humidity in the air. If the students watch and collect data; overtime in different weather conditions they will see a correlation. Students can use the Drinking Bird Demonstration to make observations and investigate motion. Have the students change the temperature of water and make predictions about the speed of the dipping cycle. Water requires heat to evaporate. In this Drinking Bird Demonstration, water from the wet felt on the outside of the head evaporates, as the vapor in the head cools, the vapor contracts.
This causes higher pressure in the lower bulb, allowing liquid to raise up the neck, the center of gravity rises, resulting in the bird to become unstable and tip forward.
When the head gets wet, the cycle repeats itself. Students can use the Drinking Bird Demonstration in an investigation to understand Center of Mass as pressure inside bird changes, so does the fluid moving up the tube.

Drinking Bird Item : DB Great centerpiece for class discussion or laboratory exploration. How does it work?
Description Simply moisten the bird's head with water, place it next to a full glass of water and watch as the bird periodically dunks its head into the glass for a "drink". It continues for hours. Is it really perpetual motion? Does it work better with hot or cold water? Does it work in an enclosed space, such as an inverted aquarium? Each bird comes complete with an explanation for teachers and suggested experiments. We have had many requests for this product over the years.
Whether you are interested in the science behind this fifty-year-old scientific toy or have just fallen in love with its adorable face, it makes a great addition to the classroom or a great gift!

Write a Review Reviews 31 reviews. May 9, Sep 25, This is the best gadget I bought among these ones. Incredible as much it works properly weeks after weeks wasting a very small amount of water.
Fashinating balance of thermodinamic and mechanical skill in a very easy and poor assembly! May 15, Feb 5, Apr 2, Owner Response: Ruth, someone from customer service will be contacting you today. Sometimes the bird's fulcrum needs to be adjusted by sliding the bird's neck up or down through the metal sleeve, which changes the center of gravity.
If this doesn't work, we will send you out a replacement. Dec 19, Bird works great Aug 2, Received order promptly but only one of the two toys worked.
Owner Response: We are terribly sorry for any inconvenience. One of our customer service representatives will contact you regarding your purchase of the Drinking Bird. The problem is most likely with the placement of the fulcrum, however, if we cannot get your bird to work, we will replace it immediately! Apr 4, My 7-yr-old grandson loved this over all the other gifts he got for his birthday.
He loves watching it and talking about it. I would recommend this to anyone. Jan 23, Alot of fond memories from childhood where shared with me when I took this to school and showed others. The kids loved watching Mr. Hothead I called him, cool off! They renamed him Bob : Fun stuff! New : hand boiler. Terms and conditions. Right of withdrawel. Complaint procedure.

Buy here your amazing drinking bird In this web shop several types and sizes of drinking birds are available. Wordwide shipping. This makes the pressure in the head slightly lower than in the body, and the liquid is pulled up the tube. The bird's center of gravity is altered as the liquid rises causing it to begin tilting toward the water and the bird takes a drink.
As the drinking bird tilts over, the liquid is eventually removed from the lower body and the lower portion of the tube. The vapor above the liquid then rushes up the tube which equalizes the pressure in the head and body. With this, the center of gravity returns to the lower body and with one swift motion, the bird swings back up away from the water. Drinking Bird comes wearing a blue hat and red feet. The liquid comes in red or blue. Please let us select the color for you. Please note this product is not a toy and is not intended for use by children under age 8.
Contains methylene chloride and may stain clothing and other surfaces.
