Travis Casagrande, a researcher at the Center for Electron Microscopeate at McMaster University in Canada, has created the world’s smallest gingerbread house,media reported. Guided by an electron microscope, he used a beam of charged molybdenum ions to “sand” the material off a small piece of silicon.
This process has led to a miniature structure that is only 10 microns long and 6 microns wide, potentially making it the world’s smallest house – or, more accurately, a model house. By contrast, a microhouse built last year by the Femto-ST Institute in France is about twice the size of the house.
McMaster University’s gingerbread house is not only small, but the details are well handled. Some of its better features include individualetched bricks, a garland on the door and a Canadian flag welcome pad. The small house was placed on the head of a snowman made of material used in The Casagrande’s lithium-ion battery research.
“I think projects like this will arouse curiosity about science, ” says Casagrande. For children and adults, curiosity about science is important. The way science is produced will arouse more interest in science and cultivate more scientific literacy so that everyone can make better decisions. “
