"For the first test I only used two balloons and two different gasses: helium and sulfur hexafluoride – the light and the heavy ones. Later on I worked out how to make the balloons float in the middle of a glass tank without connecting them to anything.
Once placed in a particular space these black objects divide it in to many equal segments and trick viewer's mind by giving him a feeling that he’s seeing a rendering from augmented reality."
