Q
Why do you sellotape you Petri dishes closed? And why do you place your Petri dish upside down?

You sellotape Petri dishes closed so that no microbes can get in and ruin the experiment.
You place the dish upside down so the condensation on the lid won’t drip down on the plate and contaminate it.
