And it certainly would have an explosive payload.
A gallon of gas is very destructive.
There was something on the internet about a new bomb that has a kill diameter of only a few feet and could be used against moving targets like a car without collateral damage.
The new wrinkle is that the when the bomb comes within a few feet above the target, a bunch of rotating blades come out and literally gnaw through the target leaving nothing but bits and pieces. Supposedly the dismembered body of that Iranian general was identified by his watch on an arm.
Knowing how sardonic US military folks are I suspect it will become known as the Burger Bomb or Bomb Burger.
