A Canadian researcher just built the world’s smallest gingerbread house
Via Travis Casagrande/McMaster University


We can’t even make a gingerbread house in normal scale, but a Canadian researcher just made the world’s smallest gingerbread house ever. What an achievement to claim! “Let’s get this bread”- him, hopefully.
According to CTV, Travis Casagrande spends his time doing electron microscopy at McMaster University. We guess the holiday spirit strikes hard in the late hours at the lab because he took on the cutest little festive project.
The gingerbread house is *drumroll please* 20,000 times smaller than a normal gingerbread house. The whole thing is about the width of a single human hair. Our giant dumb fingers couldn’t make that work.
So, the twist is that it’s not made out of real gingerbread. Casagrande’s preferred baking material is silicon, which was carved with a beam of charged gallium ions. Yeah, we also find gallium good for getting those details in.

The world’s smallest gingerbread house is complete with a wreath on the doorway, a Canadian flag, and McMaster’s logo on the roof. The whole thing sits atop an equally teeny tiny snowman. Apparently, the project took him “two very long workdays.” Travis, are we really calling that a work day?
The hope is that some youngsters see this and get excited about science. Really, we just like when people get Christmassy at work. What’s the mortgage, one nano-penny?
