Back in the early 1970s, a story was circulating about how a ouija board disintegrated when asked what was going to happen in 1975
Bill, I was there: it happened in CA. (and nearly burned down the house!). I'm still shook up about it to this day, and wouldn't believed it had I not seen it with my own eyes <shudder...>
Your urban lengend reminded me of an an anecdote that IS real:
My family was sitting in the living room during book study (held at our house), and it was almost over. I noticed that there were a few of these tiny little whitish snowflakes floating around in the air. I noticed them first, and tried to catch one, but it disintegrated (very delicate little things). There were a few others, and they were fun to play with (I nudged my brother, and he joined in on the fun, too).
A few seconds later, others in book study started to notice them, and one of the adults was smart enough to ask, "where are they coming from?"
Turns out I had forgotten to snuff out a candle that was burning in my room, and it set fire to a near-by hanging poster! No fire-men needed to be called, but I got in DEEP trouble for nearly burning down the family home AND killing all the friends attending book-study, LOL!
