Nothing screams summer more than an ice cold treat, but better think twice before reaching for these particular batch of popsicles: they’re made from sewer water — bugs, trash, bacteria and other unmentionables included.

The masterminds behind Polluted Water Popsicles are  Hung I-chen, Guo Yi-hui and Cheng Yu-ti, three art students from the National Taiwan University of Arts, whose project aims to raise awareness about water pollution. Choosing the popsicle for their translucency and general attractiveness, the trio used waste samples collected from 100 locations around Taiwan as the ice pops’ main ingredient. Preserved under a layer of polyester resin, the popsicles even come in their individually-designed wrappers stating their “flavours” and origins. Don’t say you weren’t warned.
