Raketen zum Selberbauen

Saturday, September 16th, 2017

Raketfued Rockets ist eine Website von Wasserraketen-Enthusiasten für Wasserraketen-Enthusiasten – und solche, die es werden wollen. Es wird erklärt, wie eine Wasserrakete funktioniert und wie man eine baut. Dafür gibt es eigens die Kategorie Anleitungen mit ebensolchen für Anfänger und Fortgeschrittene, mit PDF-Einkaufslisten und Erklärvideos.

Außerdem findet man auf der Seite auch Aufnahmen von Wasserraketenstarts. Ach ja, und natürlich haben sie auch einen eigenen YouTube-Kanal.

Three YouTubers on a zero-g flight:

Physics Girl: Zero G Ferrofluid Fail. (10:48min)

Veritasium: Fire in ZERO-G!! (7:47min)

e-penser: Vol en zéro-G. (35:26min) This one is in French, but English subtitles are available.

This looks like so much fun! I would accept an invitation in a heartbeat, since tickets usually cost several thousands of dollars…
