Trish's version of the Bottomless Pit
There's been a lot of discussion about inexpensive alternatives
to buying two way mirrors. After seeing Larry
Lund's page and instructions for his Bottomless Pit, I decided
to build one. After finding out that a 2' by 2' two way mirror
would cost $55, I wanted to find an effective and less costly
alternative. From the posts I had read I saw that some list members
had built pits using mirror paint or film on Plexiglas to create
their own versions of the Bottomless Pit. Spookdawg had done this
and had pictures of the Pit online. After visiting Spookdawg's
page, I decided to give it a try. So with many thanks to Larry
Lund and Spookdawg for their examples and their invaluable advice,
here are pictures of my version of Larry Lund's Bottomless
Pit. If you have any questions email me at [email protected].

of a 2 way mirror I used 1/4" Plexiglas and Privacy Mirror
