The Huge Flash Easter Egg That's Been Right There The Whole Time

This week, reporters in Vancouver are visiting a number of production venues, meeting with the cast and crew of some of your favorite shows and visiting the sets where they're shot.

This is a great opporutnity to get a sense for the world the characters live in and to look for Easter eggs you've never spotted before -- like this one.

ComicBook.com is part of that group -- and during a fairly routine trip to Barry Allen's laboratory at the Central City Police Department, we found a jar on a shelf that stuck out -- especially considering the significance of the shelves of chemicals in Barry's office to the origins of The Flash:

That's right: Cadmus Labs.

For those who aren't immediately as geeked out as I was, Project Cadmus is a quasi-governmental, super-secretive organization in the DC Universe specializing in genetic engineering. Created in 1970 as The DNA Project in an issue of Jack Kirby's Superman's Pal Jimmy Olsen, the Project has been an important component of the DC Comics scientific community ever since.

If you didn't see this on the TV show, either, don't feel bad: When I asked production designer Tyler Harron how I could have missed it for all this time, he shrugged it of, saying that the label is probably usually turned away from the camera.

Among other things, the Project is notable for having cloned The Guardian and the Newsboy Legion; while the original Newsboys were adult scientists for the Project in the '80s and '90s Superman titles, a version of their younger selves continued to have adventures with Jimmy Olsen, Superman, Guardian and others. Other notable creations of the Project are Dubbilex, Auron and some of the "Underworlders" who played a role in the Death of Superman storyline.

The significance of any of those characters, though, arguably pales in comparison to their most well-known creation: Superboy (Conner Kent), who was created in a lab following Superman's death.

"Cadmus Labs" was referenced in an episode of Smallville. The Project has been explicitly referenced or depicted in a number of animated shows as well as the All-Star Superman animated film and the live-action Green Lantern movie.

Hydrogen sulfide isn't that uncommon a compound, although it's generally found in gas form and is quite deadly.
