Behind the scenes
When speaking with Loyal, if the Courier's Science skill is too low to succeed, there will be an option for them to say, "Turn it up to 11!" This is a reference to the same idiom made popular by the mockumentary This Is Spinal Tap.

Bugs
It can remain in the inventory after the quest if it wasn't placed it into an ant mound. It can be removed with the console command.
