To start, Andrew visits Liz Harry, a microbiologist for the University of Technological innovation.
Liz will consider two swabs of germs. To start with, a cockroach will run across a filthy surface, like the kitchen area floor, and can then be remaining for two hrs ahead of the swab is taken. Andrew's fingers will then walk over the same surface area and he would not wash his fingers for 2 hours ahead of his swab is taken.
Both of those samples are then put into individual Petri dishes, then turned the other way up and put into an incubator at 37 degrees being left overnight. If you will discover any germs, they'll very easily be viewed in the morning.

Andrew's swab: There is a lot a lot more micro organism over the plate where Andrew's hand was swabbed.
The cockroach is really cleaner than Andrew. Why? Due to the fact cockroaches basically clean on their own fastidiously — constantly.
"Most species of cockroaches are form of like cats. Cats are considered to be a really clear animal as it's normally grooming itself. And cockroaches do that also," states bug collector Darrin Vernier. He lives while in the US point out of Arizona and is particularly crazy about creepy crawlies.
