A dress made from fermented beer and bacteria is going to be put on display at the World Expo 2015 in Milan .

As dress made from nothing but fermented beer and bacteria is set to debut at the World Expo 2015 in Milan later this year.
Australian creative scientist Gary Cass and fashion designer Donna Franklin added a bacteria called Acetobacter to fermented beer, which created the cotton-like fibres.
Cass told Science Network: "You add a bacteria called Acetobacter, which is a naturally found, friendly, non-infectious, non-harmful bacteria, into the liquid beer. That bacteria will ‘drink’ the beer and then convert the beer liquid into a solid fibre.”
