The collaboration with the chinese Universitiy Jiangnan in Wuxi was a new experience especially working with students from different cultures. This two-week workshop is a all about the topic „water“ and „you wu“ which means origin and effect. Bubble is an outdoor light made out of balloon material with an intergrated LED bulb. Every user can create his own design and decide how the light should look like. The size of the balloon, the length of the string and where it is going to hang. Firstly, the balloon is filled with water. Secondly, the ballon is blown up through a special lid until the favo- red size. So, the origin is a plane and with the air it becomes a 3D body, the effect.
