This is the smallest house that has been built to date

The research associate of the Canadian Center for Electron Microscopy at McMaster University Travis Casagrande (ironic coincidence) has built the smallest house in the world.

It is a tiny silicon replica of a gingerbread house. A complete structure with neat bricks and trim and a Canadian flag as a welcome mat. In turn, the house rests on the cap on the head of a snowman.

In turn, the house rests on the cap on the head of a snowman. The snowman is standing next to a human hair that looks like a redwood trunk.

It is 20,000 times smaller than a common gingerbread house. Both sculptures are tiny and invisible to the human eye. Together they do not exceed the thickness diameter of a human hair, which on average is 0.08mm.

The chosen material was silicon, which has the necessary properties to be carved microscopically.

Under intense magnification, Casagrande blasted pieces of the decorations with a beam of charged gallium ions, which acted like a sandblaster.
