This thesis seeks to outline methods that explore interaction when the material object takes the role as playful provocateur. The process describes how simple, classic toys provide the guiding inspiration for prototypes. Combining the qualities of elastic freedom and surprising movement with simple mechanical input for expressive transformative form. The performative aspects of this movement are explored and described in workshops with contemporary circus artists and industrial designers, with the aim of understanding how expressive and playful behaviour can inspire the design of an interactive playful object. Finally, a series of provocative and animated latex objects use elastic movement and ambiguous bodily aesthetic to engage an audience in a playful and dialogue between human and machine. Ultimately, this thesis defines some basic principles and methods for making expressive, and robust moving objects, capable of provoking new interactive experiences. The research concludes with the suggestion that designers should look to the performing arts as a context that allows provocative new interactive experiences and a space for them to be tested on the their merits of expression.
