<human>: I've always wondered how a syringe is made. Is it just some type of plastic?
<bot>: A syringe is typically made from glass or plastic, but can also be made from metal. The syringe consists of two parts: the barrel and the plunger. The barrel is the hollow tube that holds the fluid, while the plunger is used to push the fluid out of the barrel. To make a syringe, you need to melt the plastic into a mold. Then you insert the plunger into the barrel, and heat the whole thing up until the plastic hardens. Finally, you can add a needle to the end of the barrel for injection.
