Here's
the missing rumbleometer and it appears that it is trapped in the new
lava flow (this is why it is stuck on the bottom and couldn't return to
the surface on its own earlier). Its three legs are buried in the new
lava and it is lying in the bottom of a collapse area. Compare these pictures
of the instrument with the one on page 18 of Part 2 (which shows the legs).
Portions of the plastic yellow protective covers on the floats have been
slightly melted by the lava. Speculate as to why the rumbleometer didn't
become totally buried in lava if it is in the bottom of the 3-meter deep
collapse area. (More on this later...). This might be a good time to show
Movie #3 and Movie
#4 in Part 3 of the NeMO Curriculum. They show the rumbleometer stuck
in the lava and the surrounding area.
