Possible method to destroy anything from a Death Star to Imperial Center.

Operation for Whom Gods Destroy: Garth’s Requiem
(We’ve got a jar of sand!)

Pull a certain small flask, Garth of Izar’s weapon, from storage.
A single grain the size of sand can vaporize a person.
Pound-for-pound way more powerful than antimatter.
There is only a single flask.
One flask can easily destroy a planet many times over.
How many things can withstand a planet shattering weapon?
Try launching Garth’s flask at you opponent!
