The director of visitor experience at Little Rock's Museum of Discovery will make a third appearance on The Tonight Show Starring Jimmy Fallon.
The museum said Friday in a news release that Kevin Delaney will again travel to New York to share demonstrations on the program's May 22nd episode.
Past demonstrations included shooting vortex cannons, using a chemical reaction to send a foamy substance shooting out of beakers and creating a giant rain cloud inside the studio.
Delaney was picked from dozens of museum staffers who responded to a call from the show, which was seeking a science expert to lead Fallon through humorous but informative demonstrations.
“It’s exciting to have this opportunity to showcase how amazing science is, all while serving the museum’s mission of igniting a passion for science, technology and math,” Delaney said in the news release.
Delaney's two 2014 appearances on the show, which drew wide attention on social media and have more than 4 million views on Youtube, are both watchable at left.
