Day 3, July 26, 2007 - To get the floor perfectly level they use the two instuments pictued below.
The instrument on the left on the tripod is a laser level that is self leveling and sends out
a rotating, level laser beam. The instrument on the right that Allen is holding, is an aluminum
level rod with a laser detector attached (above his head, red in photo). The laser detector emits
a special tone when the laser detector is level with the rotating laser level.
