Spark is a unisex, multipurpose scarf designed to increase awareness of sexual harassment. Those who commonly experience sexual harassment can wear the scarf to discreetly mark locations where they were harassed, adding to a collection of data points of troubling locations. They can then pass on Spark to a friend who does not typically experience sexual harassment. When the friend wears Spark near a previously marked location, Spark lights up and literally sends a chill down their spine, making them feel more visible and uncomfortable. Spark gives a material form to the narrative of one’s experiences with sexual harassment, allowing others who may not directly experience similar incidents to build empathy.
