The best science YouTubers aren’t simply the channels with the most subscribers. YouTube shows videos to people based on how the video performs individually, not just based on who subscribes to the channel. As a result, a small or midsized channel can reach more people than one several times its size.
That’s why we rank science YouTubers by median views of their videos (the average number of people a typical video reaches). As of October 2026, the five most watched are Mark Rober, Vsauce, Veritasium, Dr Ben Miles, and Cleo Abram.
Grouped by the kind of science each channel covers. The number beside each name is the creator’s overall rank.

We analyzed the 276 videos these 32 creators published on YouTube in the last 30 days. Of those, 35 beat their creator’s usual views by 3× or more.
Here is how this month’s breakouts open, read from what each video says in its first seconds, or from its caption when nobody speaks.
“This thousand-dollar sheet of silicone mimics gecko skin to let me stick to walls from a single hand.”
Six of the month’s breakouts open by pointing at the thing on screen: a sheet of gecko-skin silicone, a ring of plasma, a satellite photo of a spaceplane. The same creators’ usual uploads seldom start this way.
JLaservideo 6.3M views · 4.5× their usualMost of these channels open a usual video on the day’s topic, along the lines of “today we’re going to discuss.” These breakouts skip that line and let the viewer see the subject before anyone names it.
“10 years later. I’m Coyote Peterson and I’m about to enter the sting zone with the cow killer and the tarantula hawk.”
Three breakouts open with the host about to do something on camera: take two insect stings back to back, swing an object through a hot lightsaber blade, or tour a backyard animal rescue.
Brave Wilderness 966K views · 8.7× their usualThe first line promises an outcome that only the end of the video delivers. The double-sting video marks ten years since the sting video that, in the host’s words, started the channel’s rise.
“If you dove into the sun, the first layer you’d hit is hot enough to make diamonds boil.”
Three breakouts open on a claim that sounds too strong to be true: a sun hot enough to boil diamonds, a rainforest under Antarctica, a finding about genetics.
Cleo Abram 9.6M views · 6.7× their usualThe rest of the video is the evidence, so the claim has to hold up. All of these breakouts are long explainers that walk through how scientists know.
The Hacksmith: “So, let’s see what happens if I swing this through the lightsaber really quickly” reached 3.1M views, 28.9× their usual.
Anton Petrov: “Living Organisms Are Starting to Consume Plastic Waste” reached 4.6M views, 19.7× their usual.
Forrest Galante: “I just learned something that is so insane” reached 2.4M views, 14× their usual.
This table shows what the science channels on this list do at each size on YouTube. Use it to judge whether a creator’s numbers are strong for their tier.
| Tier | Subscribers | Median views | Engagement | Videos a week | Sponsored videos |
|---|---|---|---|---|---|
| Macro | Under 2M | 297K | 2.7% | 1.1 | 39% |
| Mega | 2M to 10M | 467K | 3.1% | 0.9 | 18% |
| Mega | Over 10M | 1.3M | 2.1% | 1.6 | 39% |
The figures are medians across these 32 channels, from each channel’s recent videos. “Sponsored videos” is the share of videos in the 90 days to Oct 28, 2026, that carry a paid-promotion label or a stated sponsor, or are part of a brand campaign.
For a brand that wants its product in a science video, from a learning app to a telescope, these are the checks to run before you reach out.
Several of the largest channels here post one or two long videos a month. A news channel that posts daily can carry a read this week; a build channel may not have a slot until its next project is finished. Ask when the next upload is due before you set a launch date.
Some of these creators sell their own kits, subscription boxes, or toys, and others sell books. A kit brand is pitching a competitor there, so ask before you send a brief.
Two channels ran a sponsor on every upload of the 90 days, and privacy apps and course platforms sponsor more of these channels than any other kind of product. Your read sits next to theirs, so ask how often the creator changes sponsors and whether your category can be exclusive.
A hands-on product shows best in a build or a demo, where it can be used on camera. An app or a course fits an explainer, where the read comes between two parts of the story.
Parents and teachers search for science channels to show children. YouTube requires every creator to say whether each video is made for kids, so ask how the channel sets it before you plan a campaign aimed at families.
We identified and ranked these creators by searching hundreds of thousands of top-performing science videos across YouTube with Klint.
We rank by median views across each channel’s recent videos, so one viral video can’t lift a channel up the list. Channels from any country qualify if they belong to a creator rather than a studio or a broadcaster, if they are in English, and if at least half of their newest 30 uploads cover physics, chemistry, biology, space, engineering, or math.
To get this list or a similar one for yourself, describe the creators you’re looking for in the Klint web app, or paste this prompt into any AI agent connected to Klint:
Find the top 32 science YouTubers in English, each a creator’s own channel and not a studio’s, ranked by median views across their last 30 videos or their last 90 days, whichever is lower. Show subscribers, engagement, sponsors, and each one’s best recent video.
Klint is trusted by 1,000+ marketers for AI-native influencer marketing.
As of October 2026 the top five science YouTubers by median views are Mark Rober, Vsauce, Veritasium, Dr Ben Miles, and Cleo Abram.
Mark Rober has the most subscribers on this list, about 85M, and the highest median views, about 7.9M per video. The next-largest channels by subscribers are Vsauce and Brave Wilderness.
The closest on this list are the other engineering build channels: JLaservideo, Practical Engineering, Engineezy, GreatScott!, and The Hacksmith. For one experiment at a time on a smaller scale, try Steve Mould, ElectroBOOM, and The Action Lab.
By hand, search YouTube for the topic your product fits, then open each channel’s Videos tab and note how often it posts and who sponsored its last few uploads. With Klint you can ask for “space YouTubers with no sponsor in the last 90 days” and get those channels, with their median views, in one step.
Rates are private and depend on the format. A sponsor read inside a long video is priced on the channel’s usual views; an integration that uses the product on camera, or a whole build around it, costs more and takes longer to plan.
This list counts channels that belong to a creator, so studio and broadcaster channels such as Kurzgesagt, SciShow, and PBS Space Time are left out. NileRed and Colin Furze posted fewer than six videos in the 90 days, and most of Tom Scott’s recent uploads are about places and history.
Yes. Any creator can ask to be taken off Klint’s lists, and the request applies to every page they would otherwise appear on.
