The clever trick to pair participants automatically

"How do you create pairs of participants in an automated way?" 🧐

It was one of our improvement points for our session "Facilitation Circus - Juggling Introverts & Extraverts" this year at Agile Tour Brussels. Last year, after creating a line (like the one in the video), ⭐ Els Van Hecke and I just ran through it and "split" it by pairs. Didn't take much time but not super fun and hey it's 2025 so let's automate stuff.

So the idea here was to end up with pairs of participants by just giving them one prompt. Any idea what was the exact guidance?
