What they're making lately

The channel primarily produces a mix of long-form engineering-focused videos and short, impactful science demonstrations. Long-form content, like "I Blew Up A 24 Story Building" and "How to Escape Alcatraz With Basic Engineering," often ties into the creator's CrunchLabs product. However, short-form videos, such as "3 Levels of Elephant Toothpaste" and "pride comes before flop," are generating significantly higher views, often featuring quick, visually striking experiments or celebrity interactions. The tone is consistently educational and entertaining, blending scientific concepts with engaging visuals.

3 Levels of Elephant Toothpaste

217,977,584 views·Nov 2025

+1,472%

vs. median

The hook

This video immediately shows a large-scale elephant toothpaste reaction, with a person standing next to it as it rapidly expands, setting up a visual spectacle.

The thumbnail

The thumbnail shows two people standing next to an enormous blue elephant toothpaste reaction, with a '10%' progress bar overlay, suggesting a dramatic reveal or escalation.

Why it broke

This short-form video broke out due to its highly visual and dramatic science experiment, which is immediately engaging. The thumbnail effectively teases the scale of the reaction with a progress bar, compelling viewers to click and see the full spectacle, leading to 1472% more views than the median.

02

pride comes before flop

95,922,166 views·Feb 2026

+592%

vs. median

The hook

The video opens with a person in a white lab coat being drenched in a thick, orange liquid, immediately establishing a messy, surprising outcome.

The thumbnail

The thumbnail features a person in a lab coat covered in orange goo, looking surprised or defeated, with a clear focus on the messy outcome.

Why it broke

This short-form video's success stems from its immediate visual impact and the element of surprise. The thumbnail directly showcases the 'flop' with a person covered in orange liquid, creating curiosity about what led to this situation. This direct, visually-driven approach resonated strongly, achieving 592% more views than the median.

03

The SECRET to Fighting Laundry Stains #TidePartner

52,553,933 views·Mar 2026

+279%

vs. median

The hook

The video starts with a close-up of a stained shirt, immediately presenting a common problem that many viewers can relate to.

The thumbnail

The thumbnail displays a split image: one side shows a stained shirt, and the other shows a clean shirt, clearly illustrating a before-and-after transformation.

Why it broke

This short-form video performed exceptionally well because it addresses a relatable problem (laundry stains) with a clear solution, framed as a 'secret.' The thumbnail's before-and-after framing visually promises an effective outcome, which is highly appealing. The brand partnership with Tide also likely contributed to its reach, resulting in 279% more views than the median.

What to do with this

Not every tactic transfers. Here's the triage: what's safe to copy, what's stuck to this channel, and what looks great until it bites you.

Copy this

Likely to work for similar channels.

  • Create short-form videos (under 60 seconds) that feature a single, dramatic scientific demonstration.
  • Design thumbnails with clear visual cues, like before-and-after shots or exaggerated reactions, to capture immediate attention.
  • Use titles that pose a question or promise a revelation, such as "How Superglue Actually Works" or "Why MRI Machines Are So Dangerous."

Won't transfer

Worked here, channel-specific.

  • Securing collaborations with global celebrities like Ronaldo is not a replicable tactic for most creators, as it relies on a pre-existing network and massive channel influence.
  • Leveraging major brand partnerships like Tide is difficult to replicate without a large, established audience and proven track record.
  • The ability to blow up a 24-story building, as seen in "I Blew Up A 24 Story Building," requires significant resources and permits not accessible to most creators.

Watch out

Worked, but carries risk.

  • Relying too heavily on dramatic stunts could lead to audience fatigue if every video attempts to outdo the last, making it harder to maintain engagement.
  • Frequent brand partnerships, while lucrative, risk alienating an audience if they perceive the content as overly promotional rather than genuinely educational or entertaining.
  • Producing a high volume of short-form content, as seen with 14 shorts out of 25 uploads, can be demanding and potentially lead to burnout if not managed sustainably.

Your next move

A testable hypothesis built from this window.

Boiled down: if you wanted to learn from this channel's recent run, here's what to actually try next.

Test this

Create a short-form video (under 60 seconds) showcasing a visually dramatic, surprising scientific phenomenon, using a title that hints at a 'secret' or 'how it works,' and a thumbnail that features a clear before-and-after or an exaggerated reaction.

Why

The top-performing videos, such as "3 Levels of Elephant Toothpaste," "pride comes before flop," and "The SECRET to Fighting Laundry Stains #TidePartner," are all short-form, highly visual, and often feature dramatic outcomes or solutions to common problems. This format consistently generates significantly higher views than longer content.

What could break

This approach might not transfer if the creator lacks the resources or expertise to produce visually compelling and safe scientific demonstrations, or if their audience prefers longer, more in-depth explanations over quick, impactful visuals.
