yes, they contain mercury, that terribly dangerous stuff that we as kids carried globs of it around in our pockets and played with it and shined our coins with it etc.
Oh yeah, when reading your post I remember coating quarters in my pocket using mercury. Ok, so what’s the difference in recycling tubes vs those squiggly things? They both contain mercury but the disposal of them is different? I have tubes in my garage and when they’re no longer working I take them to the local hazmat dump and pitch them.
“mercury and lead and mold, oh my!”
