We have shown you the most expensive Christmas tree, weird Christmas wrapping paper, and even some odd presents, but what we haven’t shown you is the World’s smallest Christmas Card.
The nanotechnologists at the University of Glasglow in Scotland have produced what they say is the world’s smallest Christmas card.
This simple Christmas card is produced on a piece of glass that is 200 micro meters tall and 290 micro-meters wide.
That is great you say, but how big is that really? Well you could produce 8,276 of these cards on one postage stamp. Now that is super small! This was an exercise in nano- technology and showing what the capabilities for it can truly be.
Learn Something Fun: Nanotechnology comprises any technological developments on the nanometer scale, usually 0.1 to 100 nm. (One nanometer equals one thousandth of a micrometer or one millionth of a millimeter.) The term has sometimes been applied to any microscopic technology.
