I don't have any sort of media to grow bacteria with, so I wanted to know if it was possible. Is it?

I wanted to know if it was possible to culture bacteria in a petri dish without using agar. There is no media available to me at the present moment, so I was wondering if it is in the least bit possible to do so. SERIOUS ANSWERS ONLY!

According to Sagan and Margulis in “Garden of Microbial Delights”:
Each human has some 100 quadrillion bacterial cells on/within us, yet each (average adult) human consists of only around 10 quadrillion cells – So, we have about Ten Times more bacterial cells on/in us than we have of our own cells!
The point is that this is really THEIR world, they are everywhere (almost literally) we need them to survive but they wouldn't miss us at all.
Interestingly, only a (relatively) few species of bacteria actually grow well in agar; it is one of the reasons we have only been able to identify a few thousand of the (estimated) millions of species that are out there (we simply can't readily examine them well)
As for an agar surrogate, you can make your own (check out the last three links) - good luck

Whoa Nelly!
... I just opened the fridge and took a look at what's back there!
AHHHHHH !
Sorry, I'm having some fun.
Bacteria can grow in most places including you soap dish. If you use anti-bacterial, then you have resistant "bugs."

Um, haven't you ever had food rot in your refrigerator?
Ever run across road kill?
Sorry for the sarcastic replies, but bacteria grow absolutely everywhere! You just need to be a little creative, I am sure you will find a way.

Yes, I grow all kinds of bacteria without agar.

Take a rusty knife and make a small slit in your finger.
Oh, you might want a tetanus shot afterwards, but I'm sure you'll have plenty of bacteria! :o)

There's usually bacteria in the sponge that you use to clean your dishes.

you could try some beef broth
of make some beef stock using beef bones and reduce it, it will make an agarose like gel when cooled

Why can't you use media available from the science lab? (If you are a student).
