I've tried the standard "sharp shake down" method as you would with a oral thermometer but no joy. Recommendations?

Thanks @grumbler. I had planned on boiling some old spuds this evening so this has given me an extra incentive!  Will let you know how I get on.

Careful! Flashback to a curious 6-year old who found an oral thermometer, and tried it in the steam coming from a kettle. 'Bang', and mercury everywhere.

Fortunately, the mercury has had no detrimental efefct.
