Now for something completely different.
Suggesting this is a great present and toy for all people young and old.
They are cheap and fun to watch.

We had to explain how the drinking bird works in my HS chemistry class. I hate those things.Ludicrous gibs!

These are still around??

Takes me back when they first came out. It was a toy a young kid could stare at for hours, and interesting to grownups too

Thought I was on your ignore list. Grin.
The little drinking birds with plastic glass are better but they seem to be discontinued like ......
Grin. -

The explaination is worth a year of physics and chemistry in HS and college. -

It's a classic, and I still never did understand how that tiny amount of evaporation could move so much fluid inside it. -

You can google the reason why the bird works.
The evaporation cools the top cavity and that reduces the pressure in the cavity and sucks up the liquid which changes the center of mass so the bird tilts forward.
After tilting forward the liquid drains back and the process is repeated. -

What was worse was explaining why you can re-light a candle using the smoke stream. *shudder*
I passed, and the class was worth two credits, so I didn't have to take a science course my senior year.Ludicrous gibs!
