OMSI After Dark: Promsi

FEB 14, 2018 | 6-10 PM

Tease your hair to the heavens, take an awkward photo booth picture with your date and make a toast with a glass of pre-spiked punch at Prom-si After Dark! 


Shoot off water rockets, concoct chemical creations, and explore the wonders of OMSI with no kids in sight! Enjoy a glass of wine while learning about robots, tornados, or fossils. Talk to a brewer about the science behind beer, or sample products from local artisans.


All that and more with OMSI After Dark, a night at the museum for the 21-and-over crowd filled with food, drink, and science fun!

Love Stinks | After a long night of dancing, let's see what mysteries lurk in our sweaty apparel? Are funky pheromones clues to genetic compatibility? OMSI models an experiment in mate selection - take a whiff!
