Bubbles in Thermometers

I just tried the glycerol technique to fix a load of thermometers with bubbles, most were fixed but two exploded in the beaker! You definitely need to go slowly and keep a close eye.
 
Put the bulb end of the thermometer in a large bung and then bang the bung vertically up and down on the desk repeatedly (or put the whole thing in a measuring cylinder with a bung in the top as a lid and shake vigorously) and your bubbles will magically disappear!
I had quite a few that just wouldn't respond to other methods. This worked a treat! Thank you!

I don't do it with a bung I just hit it onto a thick book or pile of tissues. Never broke one yet.... I have loads to do...It is a good stress buster....
 
My tried and trusted method which has been perfected over many years is to hold at at the top, between finger and thumb and give it a sharp flick of the wrist.
If more than one bubble, may take more than one flick.

My ex-boss used to bung them in a centrifuge - bulb down /outwards obv.

Worked a treat - just make sure you balance it and don't smash them getting them in / out.
 
I've always wafted them through a flame on a tealight. A bunsen yellow flame is too strong but a tealight is pretty gentle. I've fixed 100s this way and only lost two to date but when those two went they sure went with a bang so do please wear goggles while doing it (just in case!)

This worked brilliantly for me today, thanks :)

In sheer desperation and lack of budget, necessity was the mother of invention as they say. Take one bootlace, a wide necked plastic mayo bottle and a solder iron to poke holes in the neck to secure the lace. Stand clear of everyone and spin it like a boss!!! Also a fantastic way to dry out washed, plastic pipettes if you poke some tiny holes in the base to drain. Do this second suggestion outside or everyone gets their share of the run off!
