Steam engine out of coke can help!

  1. Jan 29, 2012 #1
    Hi, my first post. So brief presentation, I'm an undergraduate mechanical engineer student.
    I hope this doesn't actually fall in homework, but it's a project that I have this semester: a steam engine car (small). I've made a bit of research and I ended up discovering the following "engine":

    Like in this video, I am provided with a soda can that acts as the boiler which has a nozzle attached to it and also pressure tested. As for the rest of the car and system, i am suppose to design it. But this steam engine is very inspiring. Anyone can explain me how this system is actually made? What I can't figure out is how the steam actually drives the piston inside. Also, is the valve necessary?

    Thanks in advance =).
