Growing Bacteria - Petri Dish

Order now at www.stevespanglerscience.com/s... You can smell a good science project a block away. In this case, multiply the fun by six and you have one of our most popular science fair project kits. You'll get six large Petri dishes, 10 cm (4 in) in diameter, a microwave safe plastic beaker, cotton swabs and the highest quality nutrient agar. This is the same nutrient agar used by microbiologists to grow really funky stuff in the lab. The instructions give you great suggestions for collecting samples and ways to gross out your parents.

Wow, "biology it stinks, chemistry it explodes and physics it doesn't work" couldn't have said it any better.

[@davidhart9106]

Impressive display of two guys who know absolutely nothing about the topic they're discussing. lol

[@mattyicee215]

LMAO

[@xghoulxx]

You could have made a 4 quadrant streak to isolate specific colonies, then do various simple stain techniques (gram stain) to view it under a microscope for easy determination of what you have on each plate. I remember in microbiology we tried the sanitizer and still found some bacteria because when you use the sanitizer there is ALWAYS natural bacteria coming out of our skin which every human is born with. I can imagine how crazy someone can get after realizing how much bacteria is everywhere.

[@stewthecat]

its just not the same without a white lab coat...

[@rickpetri]

cool one of my family members a long time ago they made up the petri dish and my last name is Petri

[@Fynniann]

Let's grow mushrooms on our shoes.

[@mattymacg09]

Not at all. All it means is that there is a greater variety of species on the keyboard than in the bathroom. Remember, the nutrient agar is creating an optimal environment for this bacteria to grow. It isn't an accurate representation of how much bacteria is in each of these places, just what kinds.

[@doingyourass]

now we should wash our hands after sitting on computer not after bathroom

[@DavidMorales-hg3xp]

Thanks Steve I've finally found a video for my science fair project.

[@Poodleinacan]

Arise, my army of bacteria! ARISE!!!

[@natecerulli167]

I am working on a school project and my bacteria isn't growing. Its been 3 days and the petri dishes don't show any sings of growing bacteria. please respond

[@HumpyLumpyPOOPOO]

how long does it take for the bacteria to appear

[@jeremyjackson4087]

The Mouth plate looks contaminated

[@Crazylaze98]

Make sure the petri dishes are in a warm area.

[@scashrock]

what kind of substrate it is...???

[@christoskettenis880]

Very informative!

[@flishkchiye]

we are doing this experiment in class I cant wait

[@11dayandnight]

lol my friends and i are doing the door to the cafeteria at our school, should be interestinggg :S

[@MultiAxian]

Yeah you could streak the bacteria to isolate individual colonies, but you'd still need a battery of biochemical tests to conclusively identify each one. a gram stain alone just wouldn't cut it.

[@spikespine3]

this was a very helpful video :-)

[@WBHify]

In order for this to have any validity, it needs to be a sterile petri dish and he shouldn't be breathing all over the agar---there are many things wrong with this demonstration! Use this video only if you want students to point out what he did incorrectly--only then is it useful!

[@bannedsk8r]

I wonder how dirty the inside of a hand sanitizer bottle is.

[@mattymacg09]

Gram staining is most definitely not an easy determinant of what is on the plate. Do you know how many gram-positive streptococcus species (not to mention staphylococcus, bacillus, etc, plus all the gram-negative species) there are? To even have a remotely accurate idea of what is on the plate would require a series of different physiological tests.

[@toadstoolnews]

What about the top of the sanitizer bottle. how dirty is that?

[@samwise401]

did this with water fountains at school, it was so bad i got sick...

[@celticslimjim]

No mention of aseptic techniques.

[@cesarrodriguez2636]

I dont want to touch my keyboard anymore.

This is the kind of video that needs a bunch of gifs spliced in

[@shiney94]

Note: The majority of microbes do not harm you :) Just relax..

[@calebcohen1355]

Do you need to culture the petri dishes in a heated area or will they develop naturally at room temperature? Would it be better in a 100 degree environment?

[@GuerillaManifesto]

@samwise401 Why? That's just the average bacteria that's everywhere, just growing in a visible colony. Nothing's changed except the quantity.

[@SoJustCool]

there are germs everywhere ahahahahahahaha

[@HH-wt4vi]

Cool ,

[@MagMonk100]

Can someone help me? I have to grow bacteria in my petri dishes for the science fair, and I went to my local science store and got the agar powder and I made the agar by mixing water with it and then I put it in the petri dish to be hardened. I swabbed all my surfaces and put them in there. It has been three days since I did that and I'm not getting anything. All I have is like a clear colony in 2 petri dishes, noting colorful or exciting like what he got. Someone tell me what I did wrong? Thx!

[@Artcat932]

It’s been 8 years. How did you do on the project?

@ehandkz I know that's what I noticed as well

In my science we did this to my mouth and I am worried what's coming :( Hopefully no harmful bacteria :D

Are you dead now ?

obvs dead

Like s soap pump it obviously gets dirty, but why does that matter, sin your about to kill whatever is on that it shouldn't matter, atleast I think.

if you need help building those let me know. I can teach you how to extract Uranium from pitchblende using Nitric acid, I can teach you how to build the centrifuges used to enrich the Uranium. I can also teach you how to mix uranium with Hydrogen flouride to make Uranium Hexaflouride. I can also teach you how to make rocket fuel using ammonia and bleach just in case you needed a delivery system.
