I can't remember the proper name for these things. They show up on beaches and maybe other places.

I am aware of what you speak. The electrical ground strike fuses the silica into a serpentine shape. Now to recall it's name? Peace Roy

I did not know this....Thanks for the information. Next time I am beach combing, I will keep an eye out for this... From the pictures, it could be mistaken for a cat turd or similar. Cheers, RickO
