In my salad daze - been there, done that ... thats smoke in the bong !!!
The 60's were very,very good to me ...
How long does smoke stay in a bong once the reefer is removed? Is there time enough for a baby to figure out how to stick his finger in the hole? That’s why I’m leaning towards the theory of a well-coated bong from much use. If the picture were stereoscopic then it would be possible to locate the position of the “cloud.”
