incubator plans will they work

[eatinmachine]

I am going to breed kenyan sand boas and childrens pythons, and if I can get my hands on them some house snakes in the near future when I convince my parents or buy the snakes. The kenyans need no incubator as they give live birth but the others do. To get an incubator running could I buy a submersible heater and set it to the temp like for childrens I need about an 84 temp. would a ten gallon or a styrophoam box work better? I would use the bricks to keep it out of the water and should I put the water up to the container with the eggs or slightly onto it not over like 1/2 inch onto? Would this work right? and what should I use? Once I get the best ideas I will toy around with it to get perfect temps.
Thanks for your responses Josh

Hey I don't know about the requirements for pythons but that set up worked for the leos i hatched a while back. I would say the styrofoam would work better as it insulates better. No quite sure what your trying to say about the heater but as the name implies it has to be underwater. This can be the whole bottom of the incubator using the bricks to hold up some egg crate which you then place either the eggs or individual containers that hold the eggs, or you could have the submersible heater in a jar of water with the eggs in containers in the incubaor. A tip someone gave me to prevent molding on the eggs: use a slight dusting of anti-fungal powder such as athletes foot powder. The layer of dust must be very thin as it can choke the eggs. Be sure to put the incubator in a place that it wont be bumped or unplugged and good luck to you!
