Here's a popular forum game with an SCP twist.

First person states an item they're putting in to 914 and the setting they're putting it in on. The next poster states what comes out, and then adds their own item/setting. Example:

Person A says "Chocolate Chip Cookie on 1:1!" Person B says "You get a sugar cookie! I put in a pencil on coarse."

Original idea from zander. I think.

Anyway ill start.
