We need MORE room!!!

if they drop on the floor. I haven't a clue as to where they go. When I sweep the floor, I get about ten pounds of trash, but not one missing part.

Hmmmmmmmmmm. Don, it looks like you haven't quite learned the "lesson of the floor".
It is a simple lesson:
Where "parts" are concerned, the "floor" is a Black Hole, from which no part ever returns ! However, and this is the important thing, as the number of missing parts grows, so does the attraction to even more parts! YES, they are actually "pulled into the vortex" that we call "The Floor", by all the other parts that are still there

Oh, Standing on your head to build, doesn't work.......the parts just fall into the void known as "The Ceiling"
