Step-By-Step instructions for an incubator for less than $1 (well almost):

1. Get two cardboard boxes, one smaller than the other.
2. Buy an adjustable temperature heating pad from the drugstore or
   a heated rock from a pet store (the kind used for pet snakes).
3. Put the heater into the bottom of the bigger box and pack the
   smaller box inside the bigger one and stuff the space between them
   with styrofoam peanuts or newspaper.
4. Place a thermometer (pet store item again) through the top of the box.
   Adjust the temperature until it is stable at say 37 degrees C.
5. Put your petri dishes inside a large tupperware box with lid, and put
   this into the smaller box.
6. Wait. Check for colonies after 18 hours. No sweat, eh?

BTW, I learned many tricks like using McDonald straws for pipets while
in a very low budget microbiology department in a New England school and
I'm not tellin' where ;-) Okay twist my arm and I will...
