Coffee cups with a difference

Coffee cups that are made out of coffee!

A German designer has turned used coffee grounds into reusable cups. The leftover coffee grounds are collected from local cafés and are then combined with natural glues and particles of wood from sustainable sources to produce a liquid that can be injection moulded to create usable objects.

Once set into the required shape the material is hard and waterproof enough to withstand cleaning in a dishwasher!

Does it improve the taste of the coffee, we wonder?
