The world’s tiniest Christmas card as you’ll never see it…
THE world’s tiniest Christmas card – 200 million times smaller than a stamp – has been created by British scientists.
The card, which is 15 microns by 20microns, includes an intricate image of a snowman and a seasonal message despite being invisible to the naked eye.
It was made at the National Physical Laboratory in Teddington, south-west London, and its creators say it is 10 times smaller than the previous record holder.
A micron is the equivalent to one millionth of a metre. The card, made on a silicon nitride membrane, has a coating of platinum which is worth 0.000002p.
Dr David Cox, a research fellow who created it with Dr Ken Mingard, said: “While the card is a fun way to mark the festive season, it also showcases the progress being made in materials research on this scale.”
