In the last afternoon of the hackthon at 15:00, there will be a 30 minute briefing session for showcase presenters led by Siebrand in the school, room 30.
Each presenter have 3 minutes of air time, including the time needed to switch computers where needed.
Methodology used: presenters line up and were briefed by Rachel. Siebrand does logistics on the stage. The introduction should be very short; around 30 seconds. Siebrand will keep time using an app on his phone and presenters are shown a 1 minute sign around that mark. Once the queue is done, people will be thanked and a question about hackathon attendees vs. non-attendees will asked.
If there is time left, we can invite the audience to participate in a retrospective.
