None of these are complicated ;(
Agar is something that is used in petri dishes as a 'feeding ground' for bacteria. It is a carbohydrate (polysaccharide), extracted from red algae.

pics or it didnt happen

@Saul Goodman Pics are commingg

Don't mind the tape on the bottom, or the sides, they are just to keep it airtight, and also to make it stick to the wall so its horizontal. I was wrong about 15 days, it was 11.

We done this in school! Its pretty cool tbh! Weird to think they can be anywhere

When I did this in school. We swabbed a kids neck sweat (he was quite generously proportioned). It created some super bacteria.

Dammm!

While studying my undergrad degree we did something similar and while spreading the agar plates with our samples I was feeling rather unwell, thought nothing of it at the time and carried on as usual.
Later that day I became rather unwell, was rushed to hospital and was told I had a meningococcal related illness (potentially mild meningitis, they didn't take spinal samples from myself but did from my colleague whom I passed it onto and confirmed the suspicions). When I went back to the lab a few weeks later and checked the plates they'd developed a rather interesting orange furry mass.... safe to say we disposed of them pretty damn fast!

What was the substance on the plates? @TCK Matt im scared of my plate now
I would rather hope whats growing isn't a reprotoxic, mutogenic, or carcinogenic

We'll never know, decided it was best to avoid opening them!
I'd advise not opening agar plates after incubation without a respirator and fume hood because of the unknown nature of what's within. It'll likely be Ecoli or Streptococcal but you'll be terrified of what you can find even on the cleanest of locations (keyboards are the scariest!)

@TCK Matt when i was looking at it, a bit of the water dripped from it onto me. I got freaked out and started spraying some disinfectant on myself xD
Yea ill be careful, when im done, im going to put some penicillin, and other antibiotics on it, and see what happens
I'll be sure to use a respirator, and gloves

A great one to do is to put some antibios on the plate before you spread them in circles (mark with pen) and then spread dirt etc between the circles and incubate, you'll see as it hits the antibios it will stop and then (hopefully) any antibio resistant strains will survive and will begin to spread throughout the plate.
Matt
As a rule of thumb I never open plates unless necessary, not much point unless you want to take samples for microscope analysis.
TacticalPanda
@TCK Matt i'm thinking of doing that, does the bacteria move? Like when your looking through with the microscope?
Matt
Very unlikely to be obviously 'moving' but most bacteria divide every 20 minutes or so, if you were able to video through the microscope for an hour or so you would see something but otherwise you won't see much.
