We wrapped the black plastic over the PVC pipe and tapped them down, on the floor we use a staple gun to staple to the wood. The dot room has been a huge success the past three years so last year we added the pool noodles wrapped in the same blk plastic to add a little 3Dish element. The dot are just florecent stickers. The main thing that is missing in the walk through is the live people we have hidden all around like in the white room with someone dressed all in white he was really hard to see with the strobes going off. The dot guy in the dot was a fan fav as he moved around and was never in the same place. We also had a laser vortex that you really can't see from the lights on video. This year we are adding a clown room and making the maze larger. The one in the video is done 21'x21 all of the cross bars on top are 3'x3.
