What kind of hook works best for science reels?
Curiosity gaps, by a distance: 39% of viral science reels open on one. Questions and bold claims tie for second at 20%.
That's the explainer's job in one line: name a thing you didn't know you wanted explained, then explain it. Curiosity gaps travelled well, 42 times followers for the middle reel, against 30 for questions and bold claims. The outlier is relatable lines. There are only 52 of them, but the middle one went 63 times past its followers. A line like "The human brain is a lot like tofu." turns a lecture into something you recognise.

How long should a science hook be?
Long enough to state the puzzle. The middle science hook is 12 words, and only 28% run 8 or fewer.
The best-travelled length was 5–8 words, at 38 times their creator's followers for the middle reel. Hooks of 9–12 and 13–20 words both reached 27, and past 20 words the middle reel reached 15. The shortest, four words or fewer, reached 25. That may be too short to set up a puzzle at all.
Should you say the hook or show it?
Show it. 49% of viral science reels put the hook on screen as text alone, and those travelled furthest by a wide margin.
The middle text-only reel reached 51 times its creator's followers. Hooks spoken alone reached 27, and hooks both said and shown reached 21. The footage does the explaining. The written line tells you what to watch for.
How do viral science hooks start?
"This" and "the" lead, with 49 and 46. "This" points at something on screen, which suits a niche built on showing. "How", "what" and "if" follow, and "did" starts 17.
