[GBlist] Microwaves - sorta off topic

["Marilyn" <timex@dsl.ca>]

Hi all:

A few days ago there was some comment about using a fluorescent bulb 
for seeing if your microwave oven was leaking.  I passed this tip on to 
some women friends, who now wonder if microwaves bend or bounce.
Specifically if your microwave oven was leaking at the back, how far 
back will they go, will they 'bounce' off a wall behind and come back at 
whoever is in front, or do they just kind of float around and go 
everywhere?  Do they 'wear out' after a certain distance or do they make 
the whole room/house unsafe?
