The Slow Mo Guys: "Rocket-Propelled Skateboard Using a Melon"
Proper slow-motion science spectacle from two of YouTube's most reliably fascinating presenters. One loud bang, then everything slows right down.
Eighteen minutes of genuine slow-motion science, watching a rocket-propelled skateboard (and a melon) in extreme detail. Our scoring rates this one neutral rather than energising, unusually calm for its bucket, with the slowest cutting pace in this batch outside our dedicated calm picks. One loud rocket-launch bang to expect, then a genuinely mesmerising watch.

Why it works
The Slow Mo Guys built a channel entirely around the pleasure of seeing ordinary (and extraordinary) events stretched into slow motion, and this episode is a good example: a rocket launch reduced to a single loud moment, followed by minutes of unhurried, detailed slow-motion footage. Our analysis measures the average shot at a notably slow 6.2 seconds, well below the frantic end of the scale.
That pacing is reflected in the overall energy score, rated neutral rather than energising despite the explosive premise, because so much of the runtime is spent in calm, observational slow motion rather than rapid-fire excitement. Our review flags one specific sensory note: a sudden loud sound at the point of launch, worth a heads-up for sound-sensitive children.
For curious kids who like understanding how things actually work, the physics explanation woven through the slow-motion footage adds real educational value on top of the spectacle.
When to reach for it
- The curious kid's Saturday watch. Real physics, real spectacle, genuinely rewatchable.
- Family co-viewing. Impressive enough that most parents will want to watch too (small confession there).
- A calmer choice within the science-stunt genre. Slower and steadier than most big-experiment content.
