What we are making: nothing. Today your machine is used by people who have
never seen it.
On your table
1
Your machine, powered and running before the first visitor arrives
1
A label: what it is, and what to do with it
1
Your notebook, open at your plan
1
Somebody from your team, standing up
What to say when somebody asks
What does it do? One sentence. The one you wrote in session 24.
How does it know? Name your sensor and your threshold number.
Why that number? Because you measured it in session 25. Say what you measured.
What went wrong? Answer honestly. This is the question that impresses people, and the team that says ‘nothing’ is the team nobody believes.
💡 Tip
Let them touch it. The temptation is to demonstrate it yourself, perfectly, while the visitor watches. Do not. A machine somebody else can make work is worth more than a machine only its builder can.
Afterwards
Everything back in the tray, checked against the bin card.
One paragraph in your notebook: what you would build next, now that you know how.
Your kit goes home with you. It is yours — keep building.
Challenge optional — only if you finish early
Explain your machine to a visitor in one sentence containing no technical words.
