I once took a ceramics class and my crowning creation was a weird undersea slug creature with a massive mouth and some kind of odd, angler fishlike protuberance. My roommates used it as an ashtray.

Students and faculty at Eindhoven University of Technology are building a 131-foot-tall replica of Barcelona’s Sagrada Familia Basilica out of ice, which I guess is cool. Of course, come summer, their glimmering towers will melt to naught while I still have that ashtray. Somewhere. Maybe in a box at my mom’s house?

The team plans to begin construction this December in Juuka, Finland, and build it in under a month using a long-forgotten and, thanks to climate change, sure-to-be-short-lived technology called Pykrete.
