Liz will just take two swabs of germs. Firstly, a cockroach will operate throughout a dirty floor, such as the kitchen area ground, and will then be still left for 2 hours ahead of the swab is taken. Andrew's fingers will then walk throughout the exact surface and he is not going to clean his fingers for 2 hours just before 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 to generally be left overnight. If there are actually any germs, they'll simply be found in the morning.
