[Or browse 30 ready-to-make ideas](#idea-bank) ## What makes a Shorts idea worth making Most “Shorts ideas” lists give you subjects: “cooking tips”, “space facts”. A subject isn't an idea. An idea that works as a Short passes four checks. 1. 1 ### One question “Why is Mars red?” is one question. “Mars facts” is a list with no ending. 2. 2 ### An answer inside 60 seconds Shorts can now run up to 3 minutes ([YouTube Help](https://support.google.com/youtube/answer/15424877)), but most single-idea Shorts land between 30 and 60 seconds. If the answer needs five minutes, it's a long video. 3. 3 ### A payoff viewers can repeat The best Shorts end with a line someone would say to a friend. 4. 4 ### A series in it If the idea can't become episode 1 of 10, it's a one-off. Series grow channels because viewers follow for the next one. Run every idea, from this generator or your own head, through those four checks before you make it. ## 30 ready-to-make Shorts ideas by niche Each idea has a hook you can use as the first line. Check the facts in the finished video against a reliable source before posting. ### Space | Idea | Hook | Action | | ----------------------------------- | ----------------------------------------------------- | --------------- | | Why Venus spins backwards | “On Venus, the Sun rises in the west.” | Make this video | | Why Mars is red | “Mars is red for the same reason old cars are.” | Make this video | | How long sunlight takes to reach us | “The sunlight on your face left the Sun minutes ago.” | Make this video | | Why space is silent | “In space, an explosion makes no sound.” | Make this video | | What a light-year measures | “A light-year isn't a time.
