I have tested the acrylic rod 2" OD
bent in the middle by 135 deg (as "U").
One end of U was fixed on the steel rack
  while another one was loaded with ~20 lbs.
The Distance between two "U" ends has been measured.

Date      time	Dist.	Weight 
-------------------------------------
13-Aug-09 16:00 29.55"	0	original 
13-Aug-09         n/a	20 Lbs  high elastic deformation
17-Aug-09  9:00	  n/a	0	the load was removed 
17-Aug-09 16:00	29.75"	0       measured after 5 hr; increased by ~5mm
20-AUg-09 16:00 29.50"	0       measured 3 days later; ~same dimension
 				within errors
--------------------------------------

Yet no indications of "Could flow" effect.
