How to hollow out huge pencil for pipe i have a few of those jumbo pencils from grade 2 or 3,wenever they used to be popular. if i take a drill to both ends do you think it will drill a nice hole i want it to be like the homemade pipe "ibreakthings" made. i want to use it for a pipe or a stem for a bong. do you think the lead will mess it up, or there might be some leftover lead which could be bad to smoke with. wat do you think?
