World's smallest gingerbread house sits atop teensy snowman created by Canadian researcher

There was Tiny Tim, and then the Little Drummer Boy — but they had nothing on the microscropic gingerbread house that is believed to be the smallest in the world and was unveiled Wednesday by a Canadian researcher.

About half the size of one made in France last year, it was cut and etched from silicon, complete with sharply defined bricks and trim, and has a Canadian flag for a welcome mat.

Travis Casagrande, a researcher at McMaster University in Hamilton, Ontario, used a beam of charged gallium ions that acted like a sandblaster.

Images provided by the school’s Canadian Centre for Electron Microscopy showed the house sitting atop a cap on the head of tiny winking snowman made from materials used in lithium-ion battery research.

The pair of decorations are barely taller than the diameter of a human hair even when stacked one on top of the other.

“While the spirit of the new decorations is festive, the intention of the project is to demonstrate the capabilities of the center,” said Casagrande, and also “stir scientific curiosity among the public.”

The center’s 10 electron microscopes and other equipment are used mostly for materials research. Unlike a traditional desktop microscope that focuses light through optical lenses, an electron microscope uses an electron beam and electromagnetic lenses, allowing for far greater magnification.
