Music by: Kevin MacLeod...When was the last time you saw one of these? This classic childrens toy seems very simple but the chemistry involved is very interesting. Do you know how it works?

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

  • Can it be re-used?

  • @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.

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

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

  • haha. Cool vid. The gurgling made me lol.

  • Thanks For Explanation

  • What is the name of the song in the video?

  • appreciated
