There won't be marauding Huns, Egyptian pharaohs or dinosaurs scampering about the Columbia River Exhibition of History, Science and Technology on Friday evening.
Instead, scientists, a cowboy, a pilot and a Hanford security guard will roam among the exhibits of the Richland museum during its annual Night at the Museum fundraiser.
About 20 volunteers will don period clothing and be stationed at the various exhibits at CREHST to demonstrate how they relate to the Mid-Columbia.
Gary Fetterolf of Richland will be playing the role of Robert Van de Graaff, the American physicist noted for his design and construction of a high-voltage electrostatic generator.
"He invented the first belt-type device to generate static electricity in the early 1900s," Fetterolf said. "Physicists have told me the one we have at CREHST generates static electricity equal to 150,000 volts, but there's very little amperage, so it's safe.
"Though it does sting," he added. "I've been zapped by it a time or two."
Another volunteer will play James Wimshurst, the British inventor credited with inventing another type of electrostatic generator in the late 1800s.
"We'll also have a manipulator or hot cell operator and Lewis or Clark -- I'm not sure which will be there," Fetterolf said.
This the second time Fetterolf has worked The Night at the Museum fundraiser.
"I did it last year and got a big kick out of it, and the people who came seemed to enjoy it too," he said.
The museum's been staging the event for about five years. Much of the museum's regular lighting is dimmed for effect, while many of the spotlights and flood lights are turned off.
"It's very theatrical, a fun event for families," Fetterolf said.
The Night at the Museum runs from 7 to 9 p.m. Cost is $5 per person in advance. At the door, tickets will be $7. Tickets are available at the museum or by phone, 943-9000. No discounts will be given to senior citizens, students, children or museum members.
