During one full week we imagined to install a huge glass container in a shopping mall.
Shoppers will Volunteer to leave all their plastic packaging at the supermarket
We will then remove all plastic packaging from their cart - replacing those packaging by glass containers or cloth bags
For each cart, we weight the plastic waste removed and then throw them in the giant glass container
We can imagine a counter saying - In X days, Y carts have been alleviated from Z kg of plastic waste
Each participant will gain a free set of glass containers and cloth bags + the symbolic image that we, for one moment, remove their "prisoner's ball"...
