I got one of those weather thingies that has the cylinder of glass bubbles filled with liquid, that are suspended in liquid. How do I figure out what the temperature is?
I got this one second hand from a dead uncle, so, can't ask him.
Does anyone else think they are stupid?

I've never really figured that out. I think it's either the bottom or the top glass bubble thing. Just get a thermastat and figure out which one reads closer to it...

I got one a think might be like yours but how to read it is it has 7 bubble like things in it and if all of them are at the top, then the bottom number is the temp and if all are at the bottom then the top number is the temp but if some are at the top and some are at the bottom you add the bottom number at the top with the top number at the bottom and then divide by 2 and that is the temp. That is what rthe instructions that came with it told me to do, so done this and then called the local time and temp number to see what the actual temp is and it is always very close. The bubbles are all big and can not pass one another so if the bubble on the bottom says 60 and they are all floating then it is 60 degress. But if all are at the bottom it will still say 60 degrees but that is not the temp. the top number is. like right now i have 2 at the top...1 says 84 and the other says 80. Then I have 5 at the bottom...76. 72, 68, 64 and 60 in that order to. So you take the 80 + 76= 156 then 156divide by 2= 78. It is 78 degrees in my house and did you notice that there is no 78 in my numbers above? I hope this helps you.

No it is not stupid...you are referring to a Galileo thermometer. The glass orbs inside are filled with oil and will rise or fall between 68 and 80 degrees Farenheit. To read it...check the medallion attached to the LOWEST FLOATING orb (or ball)

The temperature is typically read from an engraved metal disc on each weight. The lowest weight of the top set of weights indicates the ambient temperature.

is it possible that your weather thingie is a barometer?
and yes with today's technology, they're a bit arcane.

This site tells you how to read your Galileo thermometer.

They do work usually. I broke mine and I miss it. Enjoy yours as it is really accurate.
