I've just made a video with James Grime. We're both in lock-down here in the UK so we decided to make a feature of having to collaborate remotely.

While making the video I had a go-pro just out of shot filming the whole set-up. In 48 hours I will release that footage for my Patreon supporters only.

So you have two days to work out how we made the video. The behind-the-scenes footage will contain major spoilers.

I sense cheating in this video. You're both psychic and fudging the results due to also being mathematicians.

David Garrison

My assessment: At any given card one of you was guessing that you two cards would be the same, and the other was guessing that they were different. They can't be both the same, and different, so one of you was wrong. You probably had some predetermined order in which you would switch between being the one to guess the same vs guessing different. I'm guessing that'll be near the camera right next to whatever "metronome" you are using to stay in sync.

Having a Zoom video call and muting it so you just see the other's talking, isn't psychic.

Florian Linscheid

Yeah it's dangerous making a promise in hours and then not keeping it.

Matt Parker

Yes, I should have been more vague on timing. It’s coming!
