Sweat is an elaborate, over engineered mechanical distillery from which liquid pigment appears to change from blue to pink by passing through a soggy, sweaty yellow glove.
Loosely framed around the application of nineteenth century stage magic stunts such as sleight of hand and anamorphosism / the use of a device to manipulate a perception of vision or logic. The pink pigment is then recycled as it is loudly pumped upwards, instantly appearing blue again in the glass jar.
The machine repeatedly acts out this repetitive, pointless charade for the attention of the camera. Who appears to be filming a different episode.
