Guests will experience an after-hours circus complete with feats of danger and delight during Science Museum Oklahoma’s “SMO 21: Cirque Nocturne” from 6:30-10 p.m. on Friday, April 26, an adults-only (21+) night at the museum located at 2020 Remington Place in Oklahoma City. “SMO 21: Cirque Nocturne” is presented by Express Employment Professionals International.

“Cirque Nocturne” will be a circus unlike any other in that the guests are both the stars and the audience. Attendees can eat and dance with fire, try their hands at juggling both messy and dangerous things, throw knives, investigate the physics that makes walking on glass possible, test their legs on stilts, play carnival games, sit beneath the cotton candy nebulae in the newly updated Kirkpatrick Planetarium, watch as performers test the limits of gravity and much more.

“Whether you’ve been to the circus or not, most people have an idea of what the circus is — a place where the seemingly impossible and the impossibly dangerous can happen. We’ll be exploring the science and danger of the circus with a lot of fun that’s only for grownups,” said Clint Stone, vice president of programs for SMO.

The full museum will be open during SMO 21, giving guests the opportunity to explore the museum’s exhibits and gardens. In addition to themed activities and a cash bar with adult cotton candy and spiked snow cones, the museum’s café will be open with numerous entrée and snack options.

Tickets for SMO 21 are $21 in advance, $25 on the day of the event and are available online, in person during regular museum hours as well as over the phone. Tickets include all activities and access to the museum. Guests are encouraged to purchase tickets in advance as admission is limited and the event is expected to sell out.

Those purchasing tickets at the door should check SMO’s website for updates regarding ticket availability and arrive no later than 7:30 p.m. There will be no ticket sales after 7:30 p.m. and no outside food or beverage is permitted.

SMO 21, the museum’s adults-only, after-hours program for ages 21 and up, is a chance for adults to explore SMO without children in tow. Additional SMO 21 events — with themes to be announced — are set for Aug. 16 and Oct. 25, 2019.
