Smallest origami crane - 1.0mm wing span

[zxop9]

Hey so I found this picture taken with an electron microscope of what I think might be the worlds smallest origami crane



just for a reference that cylindrical thing behind it is a grain of rice

I thought this was interesting and wanted to share it with other people

edit: credit for this crane belongs to Dr. Chen at the university of alberta

wow very nice!! do you have any information how it was folded? seems a bit too small for folding it without help

I looked into that and there is no information on how it was folded. I guess Dr. Chen didn't fold it, it looks like he photographed it and never left a comment about the folder, but I could be wrong maybe he did fold it. Anyways since it is folded at a millimeter scale I imagine it was folded with very fine tipped tweezers (not the kind you buy at a market).
