How do you make a syringe?
assistant
You can use a hypodermic needle and some rubber tubing. First, fill the syringe with your desired substance. Then attach one end of the tube to the needle and the other end to a container that has a vacuum seal. Finally, pull the plunger back on the syringe until it is completely empty. This will create a vacuum inside the tube and draw up the substance from the container.
