An average German uses 3900 litres of water per day, most of which is hidden in the food we eat. This water comes from the 0.007 % of water available for human use.
The aim of the exhibition is to inform about the water consumption of food produce through an interactive and visual experience and introduce a new perspective on how to choose products. By making a reference to supermarkets, the subject is approached in a relatable fashion.
The exhibition consists of a large bottle wall with a light installation, seven interactive departments and a seating area surrounding a green water filtration system. At arrival, visitors get a credit card containing 3900l of water, which is used as a currency in the exhibition. After comparing the products displayed in the departments, visitors can choose products by showing their card to readers that are marked as barcodes. After making a choice, the bottle wall surrounding the action zone will light up to show how much water has been used to produce the chosen product. When the credit is finished, the visitor gets a printed receipt with all the chosen products and their water consuption.
While the exhibition is a medium for visitors to change the view on their personal consuption, it is also a great way to study consumer behaviour. If the price of the daily food products was displayed not only in money, but also in resources, could this have a positive effect on the environment?
