RE: Capturing mercury in a thermometer: MACRO on the table #1
What is that bubble inside the bulb?
Our handheld thermometers have clear colourless glass. But it is just as difficult to catch the right angle to see the readings of this device ))
Thank you for noticing. I was trying to show this kink bulb in the photo.
The kink is present in the clinical thermometer to break the flowing connection between the capillary and the bulb. This kink prevents the mercury level from falling. In the absence of kink, the mercury level would fall when we take the thermometer out of the mouth.
We have both varieties. This thermometer has a yellow background only at one side, for I think better readability. However, I always squint for some time to get it right! Most of the time my hands can tell the temperature of my kids with a great accuracy. I'm very sensitive to their temperature changes. Mom instincts, I guess!!!
And also can you appreciate this? I'm so happy for this capture 😆
Our thermometers have a capillary constriction instead of that bend )
It looks like you had to take a series of pictures to get visibility of the mercury column. Your patience was rewarded )))
