I think somewhere I have a photo of one. One of the things that should be considered in a fair die, beyond extra miniscule faces coin edge, die tip is the fact that the moment of a die will change depending on its attitude to the imparting force, which biases the die to certain faces.
I would start by assuming it it related to the angles between the normals of adjacent faces and the area of each of those faces. But that's not yet a workable definition, and looking at the answers so far it seems non-trivial to define it. An alternative approach would be to start with the notion of a random rotation, which should "select" one face.
But that hinges on a definition of the centre of the die. Winter - the video is actually by one of the authors of the paper linked in the answer by J.

I have a 24 and 36 sided dice that are made like that. A long regular n-gon prism with short pyramids on the ends such that it can never stable rest on any side of the pyramids is a trivially obvious die with n possible outcomes. I feel it a shame that it is relegated to almost a footnote in your answer since I feel it is much easier to picture how it works than your primary example.
Most have triangular faces to reduce circumference, but it'd be easy enough to make them all with rectangular faces like the d4 in the picture. Show 7 more comments. Loreaux J. Loreaux 3, 1 1 gold badge 16 16 silver badges 19 19 bronze badges.

Eventually it slows down and settles on a face. My intuition is that the speed it stops from is a small range. To get a "random" throw you need to throw it fast enough that it samples all the faces.

It has all been transported to the city by a fleet of huge transporters and HGVs, despite the fuel supply crisis, with an army of fairground workers and drivers involved in setting the site up.
Dating back more than years, the fair has moved around the calendar over the centuries, as well as in duration — and it even sparked a riot in the 18th century. A charter was first granted for a fair in , and in Edward I allocated six weeks in May and June for an annual event.
It grew and grew, and by the 16th century had become a day spectacular. When changes were announced in , cutting back the festivities by 11 days, a mob took to the streets of Hull to protest. From then, the official date was set as October 11, or the Friday nearest to it. Over the years the Fair has moved locations around the city, including Nelson Street, Market Place and Park Street, before moving to its present site in Walton Street in
