YouTube Video of the Week: Insane Japanese Water Jetpack

Whoa – this is awesome. Supersize a simple bottle rocket, and strap it to a terrified-looking Japanese bloke. The most impressive thing? The science involved, neatly summarised by PopSci. In short, this bloke leaves the launchpad at over 200MPH, experiencing acceleration of approx 10gs! Don’t try this at home, kids.
