Do cheap balloons from overseas portend a strike indicator market crash? That’s an idea suggested by Ed Dentry, who was turned on to the idea by Bighorn fishing guide Dave Johnson. “‘Don’t blow it up big, and then let it shrink to the size you want; that weakens it. You just puff a little, until it’s about the size of a nickel. Then tie it off with a double overhand knot. Don’t make it too big or it will be wind-resistant. If you do it right, it will last for days.'” In the Rocky Mountain News.
