Identification: was this gallium or mercury from broken thermometer? I had accidentally broken a thermometer against my computer screen, resulting in the splash of the silvery substance seen below:



I cannot remember whether the thermometer is a mercury-free thermometer, and was wondering if you could help with identification of the substance given the following information:


This picture was taken about 1-2 minutes after the initial spill
The temperature of the room was around 70 degrees F.. at most 80 degrees
The silvery substance clung to the screen as shown.
Small bits of the silvery substance seeped into the computer. However, it was fully functional in the few instances I have used it


Any suggestions or additional follow up questions would be much appreciated. Thanks!
Gallium, and Galinstan have the ability to wet glass, while mercury does not.

So it's most probably gallium (or Galinstan).
