# Half-treated sample proves product on camera

A cars format, measured November 8, 2026 by Volume. https://tryvolume.app/working/cars/half-treated-sample-proves-product-on-camera

Prove a product's benefit with a live physical test, such as a half-coated display with running water or a peel-back grip test, instead of explaining it. It worked for 3 accounts, with a median of 11x their usual reach. Type: Editing trick. Seen as: Screen recording.

## Why it works

Viewers see the treated vs untreated difference immediately, with no claim to take on trust. It works for both selling a high-ticket service and showing a product feature.

## How to make it

1. Set up a split sample, with one half treated and one half untreated
2. Run the water or stress test on camera in one take
3. Let the visible difference carry the pitch

## Hook formula

One way we sell [high-ticket service] is by having this [demo] right here.

## How this is measured

- Every post is compared with its own account's usual reach, not with other accounts. "14x their usual" means the post got 14 times the median views of that account's recent posts.
- TikTok videos and Instagram Reels are measured on views. Instagram carousels have no view count, so they are measured on likes against the account's usual likes, and say so.
- A post makes the library at 2x its account's usual or more. A format is a repeatable move (what is said or shown, or how it is edited) that several accounts used in breakout posts. It is listed here once it worked for 3 or more different accounts.
- Formats rank on how many accounts they worked for and how far above usual, damped so a fluke on one tiny account cannot outrank a format that worked for ten.
