What's inside a toy syringe

The inside of a toy syringe is empty. Toy syringes usually do not contain real injections or any liquid substance inside. Toy syringes are usually empty and are only used as part of a simulated medical device for role-playing games or props in children's toys. Due to safety and legal concerns, toy manufacturers often take steps to ensure that toy syringes are empty inside to avoid potential risks and accidental ingestion.
