Science Museum Oklahoma will explore the more dangerous side of the Harry Potter world from 6-9 p.m. on Friday, April 20 as the museum kicks off SMO 21, an adults-only, after-hours event for ages 21 and up.


“SMO 21: A Night in Knockturn Alley,” presented by Paycom, will allow guests to try their hands at Arduino wand dueling, the care of magical creatures, fire eating, potions and many more Harry Potter-themed activities spanning from Azkaban to the Hogwarts Express.


“We’re launching the SMO 21 experience with a trip into the wizarding world and down Knockturn Alley — it will be a night of unforgettable experiences from eating fire à la the Honeydukes Pepper Imps to using liquid nitrogen to give guests Dementor’s breath,” said Clint Stone, vice president of programs for SMO.


The entire museum will be open during SMO 21, giving guests the opportunity to explore SMO’s permanent exhibits like CurioCity, Big Game Theory and the smART Space galleries plus experience the museum’s Kirkpatrick Planetarium.


In addition to themed activities, the museum’s café will be open with a cash bar as well as numerous entrée and snack options.


“SMO has undergone some incredible renovations over the last several years. Adults who haven’t visited since grade school — or even in just a handful of years — will be amazed to see how the museum has evolved. We’re thrilled to welcome friends new and old for a night they’ll never forget,” Stone added.


Tickets for “SMO 21: A Night in Knockturn Alley” are $21 in advance or $25 on the day of the event and include all activities and access to the entire museum. Guests are encouraged to purchase tickets in advance as admission is limited.


Those purchasing tickets at the door should check SMO’s website for updates regarding ticket availability and arrive no later than 7 p.m. There will be no admission after 7 p.m.


Additional SMO 21 events — with themes to be announced — are planned for June 22, Aug. 17 and Oct. 19. All events will take place at the museum located at 2020 Remington Place in Oklahoma City.
