slightly off subject but my daughter bought one of those kilo bars of cadburys dairy milk.being the doting father that i am,i kept knicking a bit when she wasn't looking.in order to protest my innocence when accused i would lick the evidence off my fingers.when they dried my skin had extremely high friction and i couldn't get thumb/finger to slip against each other.
i've yet to experiment with this climbing(theres none left)but it could be the way forward.
excellent - next time I see someone stealing chocolate from a child at the crag, then licking their fingers afterwards, I'll know its not some act of crime/depravity but a cunning chalk substitute! Dairy milk has such a small cocoa content its probably the chemicals
