Progess of 1st expº

Bacteria has started to grow and is visible in most of the plates. There does not seem to be any difference between Tz and T.

Experimentation

Here are some pictures of some experiment.
I am trying to run electricity through agar in one of the petri dishes. I have already deposited some bacteria on the agar and covered the 5 plates. Now let's wait and see.



The copper wire used to run current in the plate.










Tz - Toilet water with electricity.
T, T - Toilet water without electricity.
F - Fridge door handle.
C - Control. (the plate where no bacteria, distilled water on agar.
