It may have been tempered glass. It shatters in small pieces, no large fragments to be found or cut on. That type of glass will shatter into very small pieces as if it exploded, if it has a chip, hairline crack, or any type of trauma. Funny thing about it. It doesn't always break right away.This does seem the most plausible explaination I've received, yet. So, mystery solved?
What do you think?
Oh, word of advice....
Don't eat bad apples!!!! :-P
