I 'enjoy' getting the seed coats off of AG seeds and the like; Each one is a challenge and a 'WhyDunIt?', lol. I have tweezers, two types and a knack and if nothing else, the seed leaves will grow within the seed case and eventually push the seed case offa there. Good luck, of course and be sure to do the 'Indiana Jones sand bag swap attempt' just for theatrics, lol. eric g
