Did you know old-fashioned toys still hold a place in the lives of today’s children?
Drinking bird is a little science toy that generates curiosity among young & old for more than 50 years.
Drinking Bird also known as a dippy bird or happy bird is a popular toy in the United States & other countries. This drinking bird bobs up & down & appears to drink out a glass of water
So you must be curious to know how the Drinking birds (dipping bird) toy works?
Drinking bird is a good example of a heat engine. It converts a difference between its head & its bottom into cyclical motion
What is inside the drinking bird?
The drinking bird consists of 2 equal-sized hollow glass bulbs & a long glass tube that connects the bulbs. There is water-absorbing material covering the head with 2 plastic legs with a pivot connection.
It is methyl chloride that makes dippy birds work because it evaporates very easily as it boils at just 100 degrees Celsius.
Once the head of the bird is wet & dips forward, fluid moves back into the abdomen which causes the bird to become bottom-heavy & tip-up.
Here is how the dipping bird works do?
– When the bird’s head gets wet, water evaporates cools the vapor inside the bird’s head
– Water evaporates from the head of the drinking bird
– Then the vapor in the bird’s head condenses into liquid
– Now the pressure in the drinking bird’s head is reduced as the liquid takes up less space than the vapor.
– Liquid then moves up to the tube into the low-pressure area in the dippy bird head & the cycle repeats again & again.
This dippy bird performs well in 27 degrees Celsius to 45 degrees Celsius. As long as it can reach the water, it will bob up & down as it appears to drink out water from the glass.
So this way drinking bird works
Suppose you hold a dippy bird in hand, touching the abdomen then the body heat warms the fluid in the abdomen.
Body heat increases the vapor pressure in the abdomen relative to the head. The difference in the pressure makes the fluid rises into the head & the bird becomes top-heavy
To understand more about how a pressure differential causes fluid within the bird to rise. You imagine when you use an ordinary drinking straw to suck fluid into the straw; you create a reduced pressure within the straw.
Outside air pressure is higher & it pushes down on the surface of the fluid forcing it upward.
The drinking bird is not only educational but provides curiosity among the children.
You will find many drinking bird variations, styles & sizes.
So apart from how the drinking bird toy works, there are many frequently asked questions regarding drinking birds.

2 How to start moving drinking birds?
It is the most frequently asked question. So it is very simple to get drinking bird started, you have to simply wet the head of the drinking bird & the motion of the fluid will do the rest
3 Drinking bird is a perpetual motion machine?
No, it is not a perpetual machine as the motion only lasts as there water inside the glass to cause the bird to move.
