Patio season isn’t much fun in the rain. Revamp your post-work drinks with a little culture instead at the Bell Museum’s traveling happy hour, Café Scientifique. A monthly collaboration between the University of Minnesota’s research departments and the Twin Cities bar scene, this May’s program focuses on mining around the Boundary Waters Canoe Area.

Even if mosquitoes and common sense keep you from spending a week portaging a boat from lake to lake in the name of the good ol’ outdoors, sulfide mining promises to be a hotly debated topic next legislative session. The process of extracting metals from sulfide ores poses different risks to the environment than Minnesota’s traditional iron ore mining, and as companies develop mining proposals upstate, the State Congress will be reviewing the safety of the process. Get a beer, plus the backstory on tomorrow’s news with a politick-free, science-focused breakdown of sulfide mining from Dr. Paul Weiblen, professor emeritus in Geology at the U of M. 7 p.m. $5-$12. –EK
