Analyzing the Drinking Bird

[tommymorey]

"the vapor in the bottom then pushes the liquid up the tube" ?? I don't think so. Look at it; WHAT vapor?

[offensivecoconuts]

Can it be re-used?

[renegade3355]

so when does the bird stop drinking?? does it run out of the fluid or something?

[Peterditaa]

how close does this come to a perpetuum mobile? how long can it move on its own?

[euclon]

@Peterditaa The bird will continue as long as there is cooling water in the glass and the relative humidity is less than 100%. The lower the relative humidity, the faster ther bird will drink. The thermodynamic drive is the difference between the ambient temperature and the wet bulb temperature.
