Answer:
In air-
you have to close your room properly so that a little thing cannot be come in it.
After that you have to make a small hole in it by which the rays of sun come in it , then see that ray that come in it ;you will notice that small particles move in the air.
In liquid-
you have to boil the water about an hour , after cooling it. Next step is that you have to filter the water and you will see that a lot of germs and dust is stored on the filter paper in semisolid form
