Coin flips aren't random

This article is interesting in general, but I thought it might especially interest people here because it mentions that he can flip a coin to land the same way 10 out of 10 times. I wonder if magic tricks could be created that combine coin flips and memory in some way. :thinking:

To make his point, Diaconis commissioned a team of Harvard technicians to build a mechanical coin tosser – a 3-pound, 15-inch-wide contraption that, when bolted to a table, launches a coin into the air such that it lands the same way every single time. Diaconis himself has trained his thumb to flip a coin and make it come up heads 10 out of 10 times.


I have an extremely precise motor control and have always found that i can do this and i would get confused why people use it as a 1:2 rng. There’s a stimulus associcated to how many rotations the coin will flip from its height from the way its flicked. So everytime i could feel tails or heads before flicking it and it would work.

Could do a video demo later on, we’ll see.
