> My Art I kids tackled the 1000 peace crane origami project in '96 and they are > still all over the school. We used monofilament fishing line, wooden scewers, > and paper clips to construct multileveled mobiles. One scewer was connected > from the middle 4" from the grid for the suspended ceiling. Several birds were > tied to it with the clear line and at each end another scewer with birds was > connected. Then those two each had two more scewers attached, etc. Most of > these have approximately 45 birds. The assistant principal who handles building > matters discovered that they were a good indicator of how effective the air flow > was from the ac/heat vent, so he requested that we place them about 3 feet from > the ceiling vents. They've been in place 3 1/2 years now and still look good. > The fire marshall checks our building regularly and he hasn't said anything.
