Mate Mania
The street is my favorite source of inspiration.
In this case, I found a mate (=beverage) hack to attach yerba mate leaves, a thermos bottle with hot water and a freshly prepared gourd to some sort of vehicle used on a film set.
In Argentina there is mate everywhere. The aspiring design researcher will enjoy discovering the subtle nuances of the social etiquette around the preparation and consumption of mate first hand.

Hint: DO NOT say graçias (thank you) when the cup is handed to you and DO make a good loud slurping noise when you finish your yerba mate. For a short overview take a look here.
When does knowing the etiquette matter as much as the drink itself?
