Weapon Ball Battles is a series of physics simulation videos by the TikTok user Earclacks. Each video has two circles with a weapon spinning around them bouncing around, with whoever's hp depleting the fastest from getting hit by the opponent's weapon losing. The series went massively viral on both TikTok and Twitter in late 2025.

Origin

The first Weapon Ball Battles episode released on July 14th, 2025. It has a red circle wielding a sword that increases its damage every time it hits the opponent and a green circle wielding a dagger that increases its rotation speed every time it hits the opponent. The video garnered 817k likes.

After this video, multiple characters would be added in their own battles, including:

• A blue ball wielding a staff that increases its damage and projectile explosion radius every hit
