<human>: How can I tell the difference between a syringe and a hypodermic needle?
<bot>: Syringes are generally made of glass or plastic, while hypodermic needles are usually made from stainless steel. Syringes have a plunger that is used to inject fluids into the body, whereas hypodermic needles do not. Syringes also have markings on them that indicate the amount of fluid they contain, while hypodermic needles do not.
