Paintballs
Paintballs are round capsules that contain polyethylene glycol, which is water-soluble and non-toxic dye. Surprisingly, they are safe to eat made out of materials found in foods however they do taste disgusting. Paintballs vary in dimension from .67 to .71 caliber but numerous factures influence the exact dimensions. Even though manufacturers develop paintballs that are meant to be spherical, they are rarely perfectly circular because they are very sensitive to moisture and heat. Typically, the more expensive paintballs are rounder and developed more to perfection.
