A human-sized cannon may be smaller and lighter than a building-sized balloon, but it is a formidable and powerful weapon. Cannons have been historically used in warfare to deliver devastating blows to enemy forces. They are precision-engineered machines that can launch heavy projectiles at high speeds with great accuracy.

In addition to their destructive capabilities, cannons also have a symbolic and historical significance. They are iconic representations of military power and have been featured prominently in many historical battles and events. Owning a human-sized cannon could serve as a tribute to this rich history and a reminder of the importance of military strength and strategy.

Furthermore, a human-sized cannon could also have practical uses beyond warfare. It could be used for ceremonial purposes, special events, or even as a decorative piece in a museum or historical site. Overall, while a building-sized balloon may have its own charms and appeal, a human-sized cannon offers a combination of power, history, and versatility that make it a unique and intriguing choice.
