Why oh why would you keep using the regular 9cm petri dishes for a class of year 9 kids when these small petri dishes will grow the bacteria and fungi just as well!
You'll be able to fit them all into your incubator, and then pop the lot into the pressure cooker when done.
It's time to think TINY people!
