Special Edition

On the 20th of July join us for an afternoon of creation and exploration of amateur rocketry by creating far-and-high flying bottlerockets, followed by a BBQ and drinks, and then some related This Happened talks.

This is a co-production of This Happened Rotterdam, Amsterdam and Utrecht. This is not a regular This Happened, let’s be honest, but we thought it would be a lot of fun anyway. Everyone is welcome to join, but we’re offering the first of the 50 spaces to people who have spoken at This Happened and the wonderfully crazy people who have visited almost every episode. If you feel you belong in a backyard with bottlerockets and smiling happeneers, email us.

The day

  • 11:30 – Doors open
  • 12:00 – Lunch
  • 12:30 – Rocketbuilding. Bring your own plastic bottles. Willem-Jan Renger, experienced rocket builder is instructor of the day.
  • 18:00 – BBQ
  • 20:00 – Some unconference-style talks in TH format but without fixed schedule.

Afterwards you’re very welcome to put up a tent and stay the night. Please let us know in advance if you like to stay over.

10 euro. For that you will get food (BBQ, salad) and drinks (juice, beer), but it would rock if you could also bring something tasty of your own.
