In the work “Play Safe” by Christina Marie Pietsch from 2018, the 35mm cartridge format, with the dimensions Ø 4cm x 22cm, which is a common format for US Army fighter planes, is translated into an alternative narrative. Due to the change of material (pH-neutral silicon) and colour, the objects are given a completely different look and become the object of speculations. Cruelty and play, pleasure and destruction. Two changes in register and everything is possible.
