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.
