A Canadian researcher has built the world’s smallest 'gingerbread' house out of silicon which is smaller than the width of a human hair.
The Canadian Broadcasting Corporation (CBC) reported that Travis Casagrande, who works at the Canadian Centre for Electron Microscopy in Hamilton Ontario built the tiny house (complete with a brick chimney and a wreath over the door) using a device called an “ion blaster,” which uses charged ions of the element gallium, and works like a sandblaster to carve and etch the object onto a piece of silicon.
What’s more, the edifice sits on top of the head of a larger figure of a snowman. The entire construction is dwarfed by a human hair in images released by the organization. “Compared to the size of a typical gingerbread house that you might buy in a grocery store kit, mine is 20,000 times smaller,” Casagrande told the CBC.
