We’re Back!

LSOP celebrated our 29th Annual Open House on February 29, 2020. We were super excited to celebrate our 30th, but the world got kind of crazy and we had to cancel the big in-person event and move things online. We’re super excited to be back in person for the sequel in 2024!

What Is Open House?

Every year, thousands of people flock to the Lory Student Center for a day of fun, hands-on science at the Little Shop of Physics Open House!

This event is free and open to the public. It is appropriate for folks of all ages, from pre-K to gray! Along with over 300 hands-on homemade science experiments, you can check out interactive presentations and activities hosted by our Science Partner Groups from CSU, Colorado, and beyond!

Open House will be in the CSU Lory Student Center, on the 3rd floor. We recommend parking in the Engineering Parking Lot or the Morgan Library Parking Lot on CSU Campus. Public transportation is also a great option: CSU is served by several bus routes, including the MAX.

Most parking on campus is available free of charge on Saturdays, but please check the signage in the lots to confirm. For more information, visit the Parking and Transportation Services Website.

We’ll have more details about Open House 2024 as the date gets closer, but here’s what we know for sure: It’s going to be free and fun! Check out this video from Open House 2018.


Interactive presentations will be held in the Lory Student Center North Ballroom every hour during the day. Come join the fun!
