One day one of us stuffed a cheese puff up the air vent of the van.
I am uncertain about the thought process that inspired this gesture, but I know we found the result to be astounding.
The cheese puff traveled through the ceiling of the car and suddenly reappeared, popping out of another air vent.
For our entertainment we continued shoving our snacks into the air vents and eagerly awaited their emergence from other vents.
Sometimes they never emerged again but this did not stop us from stuffing the air vents with cheese puffs.
(Shout-out to socially awkward home-schooled families with 12 passenger vans that smell like cheese.)
