If you add things like arm position and rotation, you can add even more bits. Using 4 arm positions and 2 rotations, you can get a full byte of data with one hand.
The trick is to be the one making the bets and to word them in a way that makes the losing side sound like the winning side (or one that generates enough curiosity about how you can actually do it that people accept the bet knowing you probably have a trick).
I can count to 31 in one hand in binary. It’s not a super useful skill, but it’s won me a bar bet more than once.

I want to go to the kinds of bars where counting in binary wins bets. Most of the time it’s things like “open a beer bottle with your eye socket”.
