The Science History Institute is closed for Independence Day on Friday, July 4, and there will be no First Friday event.

Finding clues, testing evidence, uncovering secrets—it’s all part of the game at this month’s mystery-themed First Friday!

Join us for a night of “whodunits” and solve a historical forensics murder mystery. We’ll gather clues around the museum in your detective’s notebook and test our answers against a panel of experts. Play matching games, tour a new rare book exhibition about the science of blood, and enjoy chills and thrills…if you dare!

About First Fridays

Spark your curiosity while exploring the exhibits after hours! First Fridays bring together a myriad of activities covering everyday science, historical oddities, and everything in between. Grab your friends, and kick off an evening of discovery, surprise, and a little nerdy fun.
