I used the wrapper from a take-out sandwich from Jack in the Box. It works. Eight clean folds. It was greasy, from a grilled deli-melt, I don't know if that contributed to its manifoldability.

Mythbusters said it couldn't be done.

The paper has about a 2:1 dimensional ratio at the start, so after the first fold, it is like a square, still very thin, and there are only 7 more to go after that. I think that's the secret.

Manifoldability? WTH is that?

I like it, though. It should be a word just because it's fun to say...

Grain of salt alert. While your statement regarding the Mythbusters was true for thick paper it was not true for thin paper.

MythBusters (2007 season) - Wikipedia, the free encyclopedia

"It was impossible to fold a piece of letter-sized (8.5" × 11", 216 mm × 279 mm) 20 lb (75 g/m²) copy paper with perpendicular folds more than seven times. The thickness of the paper grew geometrically with each successive fold, and after the seventh fold the paper was just too thick to fold without breaking. Breaking the rules of the challenge, Grant showed that folding a particularly thin sheet of paper in the same direction 4 times then 4 times the other way, it is possible to fold the paper 8 times. The MythBusters then laid out a football field-sized sheet of interconnected paper (170 × 220 ft (52 × 67 m)), and due to the reduction of its area-to-thickness ratio (and with help from a steam roller and a forklift), were able to perpendicularly fold the paper 11 times. Other methods of folding a piece of paper (such as with alternating folds) proved able to break the fold threshold of 7 for letter-sized paper, and perpendicular folds of more than 7 are theoretically possible with thinner paper"

If you could fold a piece of paper in half 50 times, how thick would it be? Assume 500 sheets to an inch thick (1/500th in thick). No calculators. Just guess for fun.

One third the distance to the sun, or about 35 million miles.
