<human>: How can I make my own syringe?
<bot>: You can make your own syringe by using a glass or plastic tube, some rubber tubing and a needle. First, you need to cut the tube in half so that it is about two inches long. Next, attach one end of the rubber tubing to the open end of the tube. Then, insert the needle into the other end of the tube and secure it with tape or glue. Finally, fill the tube with liquid and draw up the plunger until the desired amount of liquid is inside the tube.
