Thermometer broke! Are little wieghts dangerous?

If the thermometer indicating fluid was red, it is just colored alcohol and won't hurt anything.

I am not sure if the weights are lead or not, but in any case, I have had one break before and it never hurt anything. I just got out what I could and left the rest.
 
I believe they are made of iron, not lead, so I don't think you'll have a problem. Just like heady said though try to get some out if you can.
 
The magnet will work if they are metal. Try picking them up with chop sticks! Now THAT would be a trick!:p
