You couldn't nibble this Bouncy. Tastes foul!!!! (yes I tried the old "give it a quick lick if you smudge it" BLEH!) ANd I dont have long nails either.... but they are like steel. I have to use nail clippers to cut them.
Besides.. it most probably has metal ground up in it... you would set off the alarms at security points if you ate it.
mC.... but but but what?
Talking of science.... (again).... want to know why I have never ever bitten my nails? A science teacher once took swabs of our fingernails in class once and GREW the results!

Ewwwwwwwwwwwwwww! I never had the inclination to ever put a finger in my mouth ever again.
Just keep swimming... just keep swimming.. just keep swimming....
