It&#x27;s not trivial for a middle-schooler to make an incubator and I&#x27;m sure this girl got advice from microbiologists that would have taken her much longer to gather on her own.  They had all the equipment she would need right there (sterile loop, agar plates, bunsen burner, lab grade ethanol).  Plus, she probably had a bunch of equipment to make it easier (test tubes, tube shaker, that light she&#x27;s using to examine the plates).  So really she had a huge advantage over someone doing it on their own.
