Lithuanian artist Tadao Cern is inspired by everyday objects. He creates seemingly simple artworks that explore ordinary objects. Cern worked as an architect before transitioning to photography and then visual arts. Black Balloons was born from the experimentation of materials and the physical relationship between objects. The installation is conceived in various formats but earlier incarnations involved filling two regular latex balloons with two different gasses: helium and sulphur hexafluoride. He eventually worked out a way to make the balloons float in the middle of a glass tank thus the compositions grew in size and complexity.
