Science in the Fast Lane

On your mark, get set, GO to OMSI as we pick up the pace for a high-energy look at what makes things move FAST. 

Shoot off water rockets, concoct chemical creations, and explore the wonders of OMSI with no kids in sight! Watch aerialists fly overhead and enjoy a pint of beer while learning about the science behind cars, explosions, and cider — there's a new theme every month. All that and more with OMSI After Dark, a night at the museum for the 21+ crowd filled with food, drink, music, and science fun!

21+ only, IDs required. OMSI After Dark is held the last Wednesday of every month.

Want to get a head start on the science fun? Drink up at happy hour starting at 5pm in OMSI's eatery, Theory! The event takes place before OMSI After Dark each month and features a special menu including stone hearth pizza and local beer and wine.
