OMSI After Dark: Brewfest

21+ Only | ID's Required
Science is brewing at the 5th annual OMSI After Dark: Brewfest. Don't just drink beer, learn beer! At our 5th annual brewfest, sample beers from local breweries while learning how beer is made, the variety of hops and enjoy some fun beer tricks while you're at it!

Freezer Flash | How do you freeze a beer in mere seconds? Just add a little science and slam it on the table.
Drunk Goggles | These goggles simulate different levels of impairment. Drive a remote controlled car and walk the line.
Beer Geyser | Science is all about inquiry. Like inquiring, “What happens when I bombard a 40oz with ultrasonic sound waves?”
