Inspired by louis pasteur's swan-neck flask experiment, a microbiology student was interested in repeating this experiment using hay (dried grass) infusion instead of nutrient broth. he placed a few strands of dried grass into a sugar solution in an open neck flask, drew the neck of the flask into a swan-neck shape using a flame and then boiled the contents of the flask for 30 minutes. after 3 days of incubation at room temperature he was surprised to see bacterial growth in the flask. does this experiment support spontaneous generation? if not, how would you explain the growth bacteria in the flask?
