Squeezing air out of a ketchup bottle before capping it prevents it from exploding when opened.

Infact verdict: Mixed (43/100).

The claim that squeezing air out of a ketchup bottle before capping it prevents it from exploding when opened lacks strong evidence. The available web evidence primarily consists of anecdotal posts from Reddit and a Chowhound article, none of which provide definitive or scientific support for the claim. The sources are not authoritative, and there is no consensus or expert verification. Therefore, the claim remains unverified and speculative.
