Join Pacific Science Center as we dance, drink and discover – the second annual Theory is Seattle’s premier outdoor party of the summer.

Discover the quintessential elements of the Pacific Northwest with a night of craft cocktails, wine and beer under our iconic arches in the beautiful summer sun. Stop by each of our open bars – a different signature drink at every one – and learn the science behind them. Dance the night away, watch a laser show or roll up your sleeves and build your own creation in Tinker Tank. Take our word for it: this is one party you will not want to miss!

Pacific Science Center invites you to party with a purpose; ticket sales go directly to supporting informal science education and enabling access for all. Join us for Theory 2018 as we dance, drink and discover, all in the name of science!
