This one of those things that you know MUST exist, and it looks kind of familiar yet – what is it? Well, it’s e pluribus unum—one of many. And it’s the result of a non-consensual collaboration between two teams of scientists.

Though it saw wide use, it wasn’t used to its ultimate purpose, and it was soon replaced by better technology.

Hint 1:


Named by Benjamin Franklin

Not a weapon, but quite dangerous.




It’s one cell of a battery complex for a GUPPY equipped submarine.
