Woops. I just realised I made two mistakes in my experiment.

1. I had initially forgot to label my containers with which plastic wrap was on which container, and when I had gotten around to doing it I have a feeling I got confused with a few of them and labelled them wrongly.

2. I found a little crack in one of my containers.

Guess that didn't go well. I'm starting it up again soon, and this time I hope I remember eveything I forgot.
