How to make a science explainer video
A science explainer has a harder job than most formats: it must be simple enough to follow and accurate enough to survive an audience that includes people who know the field.
The resolution is not simplification. It is choosing a narrower question. "Why is the sky blue" works in sixty seconds; "how does light work" does not, and attempting it produces something both vague and wrong.
You end with an illustrated explainer that holds up to a knowledgeable viewer.
Steps
Narrow the question until it fits
One mechanism, one phenomenon, one question with an answer. The instinct is to cover a topic; the format rewards answering a question. A video that answers something specific completely beats one that surveys something large partially, and it is far easier to make accurate.
Find the one analogy that carries it
Most good science explainers rest on a single comparison to something familiar. Finding it is the real work. Two competing analogies in one video is worse than none, because the viewer spends the second one re-mapping what they had already understood.
Check the claim against a primary source
Published research, textbooks or official scientific bodies — not other videos on the same subject. Science content is heavily recycled, and an error repeated across ten channels is still one error. This is the step that decides whether your comment section corrects you.
Say what you simplified
A clause acknowledging that the real picture is more complicated costs three seconds and buys most of your credibility with the people most likely to object. "This is roughly right, and the full answer involves..." is a stronger position than confident incompleteness.
Illustrate the mechanism, not the topic
Generated visuals should show the thing you are explaining happening, in the sequence you explain it. Decorative science imagery — generic molecules, generic space — adds nothing a viewer learns from, and it is what makes an explainer feel like a slideshow.
What you end up with
A short video that answers one specific scientific question completely, rests on a single clear analogy, names what it left out, and illustrates the mechanism step by step rather than decorating the subject.
Watch sample videosWhen this isn't the right approach
If you cannot check the claim against a primary source, do not make the video. Science is the format where being confidently wrong does the most reputational damage, and the audience contains people who will know. This is also the wrong format for anything contested at the research frontier, where a sixty-second explainer necessarily picks a side it cannot defend.

Generate a videoFrequently asked
How much can you explain in sixty seconds?
One mechanism with one analogy. That is the honest ceiling. Treating it as the target rather than the limit is what separates explainers that land from ones that feel rushed, and the most common failure is compressing a five-minute explanation rather than choosing a smaller question.
Do I need a science background to make these?
No, but you need to check everything and be willing to say what you do not know. Careful research by a non-expert produces better videos than confident recall by someone who half-remembers a degree. What you cannot do is skip the sourcing step, because that is where the credibility actually comes from.
Should I cite sources on screen?
In the description, always; on screen, where a specific number or study is doing the work. Citations in the description cost nothing and are what a sceptical viewer looks for. On-screen citation for every claim clutters the frame without adding much, so reserve it for the load-bearing facts.
How do I handle a mistake after publishing?
Pin a correction. It is the cheapest possible fix and it consistently reads well — an acknowledged error damages credibility far less than an argued one. Editing the description helps too, but the pinned comment is what people actually see.
