i would say get some sterile water (clean water - free from any microorganisms) and add some pure sugar into it !!
here you go !! bacteria will live beutifully there untill the sugar is all used up ...
[dont put too much sugar, as this can kill everything there .. too much sugar will cause the cells to burst, and by the way this is why jams/honey ...etc is hard to grow any bacteria on (except fungi ofcourse)

The simplest way is probably in a broth: take a colony from an agar plate and dip it into some liquid medium (eg nutrient broth or LB). I think you can also grow it on collagen with a liquid medium, or gelatin.

Nope. Gelatin is a real good one too. It's also available in a film, cut to fit a petri dish. You need to get your hands on a laboratory supply catalogue.
