Next year, the Japanese space agency is planning to throw paper airplanes (aka origami space shuttles) from the International Space Station with the hope that they will make it to earth intact.
It is yet to be decided whether Wakata himself will throw the paper planes or whether he will use the space station's robotic arm.
The planes are made from sugar cane fiber paper treated to withstand high temperatures and strong winds. (via waxy no idea where I got this)
Update: The launch of the origami planes has been scrubbed. (thx, edieraye)
Microscopic auto-origami. Just add water! (And they fold right up.)
How to make X-wing fighters (from Star Wars) out of Paris Metro tickets. I gotta try this...I've got about a zillion of these laying around because they make great bookmarks.
