Testing If You Can Breathe Underwater! has 133,362,955 YouTube views as of Nov 13, 2026, 09:40 UTC.

Where does this number come from?

Why doesn’t the count go up every second?

YouTube updates public view counts in batches, and can hold them for a while as it checks for invalid views. CountDeck never fills the gaps with an estimate, so the number only moves when YouTube’s does.
