Paintballs are not safe to eat. While the outer shell of paintballs is typically made from non-toxic materials like gelatin or polyethylene glycol (PEG), the fillings inside are not food-grade and are not meant to be ingested. The fillings often contain water-based paint or similar substances designed to break upon impact, marking the target. Ingesting these substances could lead to potential health risks, including gastrointestinal issues, choking hazards, and possible allergic reactions in some individuals.

Interestingly, there have been some attempts to create edible paintballs using food-grade materials, but these are not widely used in standard paintball play. Edible paintballs could be an exciting prospect for novelty events or specific games, as they might offer a more interactive and immersive experience for players. However, it is essential to ensure that any edible paintballs used are made from safe and non-toxic ingredients to avoid any potential health hazards.

In conclusion, while paintballs may be non-toxic, they are not safe to eat due to their non-food-grade fillings. It is crucial to adhere to safety guidelines and use paintballs only for their intended purpose in paintball games and recreational activities. If you are looking for a paintball-like edible experience, it is best to explore alternative options specifically designed for consumption and avoid any potential risks associated with ingesting non-edible paintballs.
