After two years of Research & Development toward producing an Astral Projection Device, I had all but given up. What I wanted was essentially a "Bic Pen" of Astral Travel, which meant to me that it worked first time, every time, without fail.
Then the "Big Duh" hit me.

And that's exactly what I did,... find out more about astral projection.
