This is the part where she tests her hypothesis that wooden utensils would grow more bacteria than plastic ones.

Answer:

Liz took a swab from the plastic utensils after cooking with them for a full day, and then repeated the process with the wooden utensils. She then cultured the bacteria from each swab in a petri dish.
