[Plant-education] Pressure Bomb Lab

[Sustainable Rider]

At the last minute, I'm trying to devise a lab that allows students to 
use a pressure bomb to ask an interesting plant water potential question 
(this is my intro botany class I can't stop fiddling with).  I've got 
two pressure bombs and have to run this lab in late February.  I usually 
do this outdoors in a fall ecology class but that's not really an 
option  at this point. Anyone have any tried and trues they'd care to share?
