In need of URGENT HELP!!!!!

Not sure what that video has to do with thermometers.
But the little silver balls are no mercury, their simply weights to help weigh down the thermometer. The part that tells the temperature is most likely an alcohol based solution as well.
Most thermometers don't contain mercury.
Not sure what the little balls are made from, lead perhaps? Not sure if their magnetic. But their not mercury.
