Open Question: I want to make a fire on my patio (camping theme). How would I do that?

So I live in the city and have a busy life. Going camping in the woods is out of the question. I do want to have a camp night for my 6yo though. So I have a large patio with a concrete floor. I set up a tent on it. I have two sitting chairs and marshmellows to roast.

I want to know how I can make a small fire to roast hotdogs and marshmellows without burning down the apt. complex. Like what materials I need and what not.

People have bar-b-ques on their patios and things of that ilk so i'm sure it's OK, but i'm really not sure how I would do the fire thing.
I know they sell those patio fire pits at furniture stores, but I really don't want to spend $300 on one so I can have a camp night theme with my son.

LIke would I use a coffee can and twigs? I'm just a city girl with no idea about fire stuff. lol

Im clueless.

I need some ideas. Then I will call the fire dept. to see if those ideas will be safe for my dwelling. I needs some ideas first though.

Please help me with ideas.
