I know that black light is often used to see the germs on people's hands but is their anyway we can examine the germs on people's hands without having the surroundings be completely dark (what is required for black light to work) or using a microscope? I am trying to show a roomful of people the germs on my hand but the surroundings aren't gonna be completely dark and there is no way i can use a microscope and show them the germs on my hand.

I know that black light (UV) is often used to see the microbes (colloquially referred to as germs) on people's hands but is there any way by which we can examine the microbes on people's hands without having the surroundings be completely dark (what is required for black light to work) or using a microscope? I am trying to show a roomful of people the microbes on my hand but the surroundings aren't going to be completely dark and there is no way I can use a microscope.
