I have taken a new interest in hose inflation videos recently and have discovered two worthwhile examples:
This model has a clipstore with several hose inflation videos.

And Maxgrowth at taylor made clips just made a water hose inflation video. Enjoyed this one because of the water sloshing sound effects as well as the actress struggling with the hose.
