[Phys-l] Fun trivium: bump a sleeping king penguin and he won't wake, but tread not his toes.

[Bernard Cleyet <bernardcleyet@redshift.com>]

"Some science experiments yield inconclusive results. Not this one.  
Dewasmes and Telliez write that 'a slight change in pressure exerted  
on the feet of a profoundly sleeping penguin appears to be a powerful  
arousing signal of danger. This does not appear the case when the  
back of this sleeper is hit.'"

Why?
