An engineering video about a trochoid pump might not be something you'd ordinarily watch (unless of course you had a trochoid pump-related issue that needed resolving). But when the YouTuber narrating it suddenly gets interrupted by his daughter halfway through, it becomes a must-see.
In the clip above, AvE is midway through an explainer when his little girl suddenly bursts into the room complaining of an "ouch ouch" (4:30 in).
Cue four minutes of the most adorable father-daughter engineering you're ever likely to witness.
The best part? When mom shouts that there's cake at the end of the video, and the two immediately down tools to go and get some.
