Guy explains rocket science via water jetpack

Watch this crash course on rocket physics with water jetpacks and fire extinguishers

Science YouTuber Derek Muller, aka Veritasium, provides awesome videos related to science and physics. In his latest video, he dons a water jetpack and discusses the physics related to rocket science (and earns a few bumps and bruises along the way).

Check out this video to learn more about how rockets work - you don't need to be a rocket scientist to understand it.

Of course, this wants me to go out and try a water jetpack as well - but this likely also shows why normal people don't have their own jetpacks, like science-fiction cartoons from the 1950s.
