(World Small Christmas Greeting Card)
British scientists have designed a miniature Christmas greeting card.
It was produced in the National Physical Laboratory in Britain. It is 15 micrometres long and 20 micrometres wide.
This greeting card is covered with silicone nitrate platinum.
It is 200 million smaller than a postal stamp. It is 100 times smaller than the smallest greeting card.
A snowman picture has been drawn on the card. Christmas greetings are written on it too.
The creators of this Christmas greeting card said, this is the smallest greeting card ever.
The National Physics Laboratory researchers Dr. David Gokes and Dr. Gin Mingert created this card.
