These popsicles look like the fancy sort of thing which you see at a quirky organic artisanal food truck, but one bite could leave you very ill indeed and the reason is that they’re actually made from sewage found in the contaminated waters of Taiwan.

They were made by 3 design students for the Polluted Water Popsicles project, which tries to raise awareness about growing water pollution due to fast economic growth and urbanization. Water was taken from 100 various water sources in Taiwan and turned into frozen toxic popsicles before Hung I-chen, Guo Yi-hui, and Cheng Yu-ti from the National Taiwan University of Arts made them with transparent polyester resin. They even made wrappers for them that shown the different regions from which the polluted water samples were taken. While the trash in the water was diverse, about 90 percent of it was plastic, and the popsicles include everything from bottle caps and plastic bags to bottles. It’s an easy yet powerful way of getting us to think about water pollution from a completely different perspective.
