We wouldn’t eat these “popsicles” if we were you. Concocted by Hung I-chen, Guo Yi-hui and Cheng Yu-ti, a group of students from National Taiwan University of the Arts, the frozen treats comprise sewage from 100 different locations across the East Asian island nation. Hung and company froze their samples—bottle caps, plastic wrappers, and all—to illustrate the scope of Taiwan’s water-pollution problem. To preserve their creations, they dipped the popsicles in a polyester resin.

They even designed wrappers for each frozen non-treat based on the locations they sampled from. Unappetizing “flavors” include “Yang-tzu-chou Drainage,” “The Large Ditch in Tianwei,” and “New Huwei Creek.”

Hung said they chose to make the popsicles to illustrate the importance of clean water. (Popsicles are, after all, mostly H2O.)

“They’re made out of sewage, so basically these things can only be seen, not eaten,” Hung told Mashable. “[Having] pure water, a clean water source is actually very important.”
