how do you get a cold?

well there’s a special kind of germ called a virus. a virus is the smallest living thing on earth! for example here’s a experiment. this is how you can grow your own germs. get three tall cups. fill each one with tap water. put a cube of bullion in each cup. put vinegar in one and salt in the other leave the third cup alone. this experiment will take 5 days.
