THANK YOUUUUUUUUU! Favorite part is "harnessing the power of SCIENCE". Second favorite is "floaty eyeball." Now I must blog this so PEOPLE WILL LEARN.

I am not associated with them, but this site:

has a cool product and a great discussion of crumple vs. fold...

Thanks for the PDF!

Wow... I love it when, after you 'know' something instinctively for years, you find out that there is a scientific explanation for it. You had me at floaty eyeball. I am forever in your debt, and will print up and hand out these pamphlets to everyone i know. thank you. thank you. thank you.

Now i can sleep.

I've given the whole over/under thing some thought in the past. Consider this conjecture: men prefer the over version, because they only use toilet paper to wipe from behind. Women prefer the under version, because they wipe from the front more often.
If you wipe from the front, unrolling the paper from the back of the roll, tearing it, and wiping yourself can be done in one smooth motion. If you wipe from the back, you have to fold the paper, which means you're likely to use both hands and so you unroll and tear the paper with your non-wiping hand, fold it using both hands, and leave it in your wiping hand to finish the job. This sequence of motions works better with the paper unrolling from the front of the roll.

Chris,

Do you consider yourself to be a scruncher or a folder?

A folder, no question.

I made a huge poop today and there was NO paper. I wouldn't have cared if it was overhanging or underhanging. I needed PAPER. So I used your socks.

This is fantastic! People think I am a freak for caring how the toilet paper is hung. I have been resisting the temptation to reverse the under hung tp roll that my boyfriend installed yesterday. I should just be thankfull that he replaced the emply roll -right? This brocure will come in very handy.
