do the tubes that the co2 passes through go in the plastic bottle through the top?

What a fascinating 'able! I was beginning to worry about where the CO2 was coming from but it comes in a box so that's that sorted out. What does one do if there isn't a handy tankful of the stuff round behind the laboratory? I suppose you could make it a condition of admission to your house that every caller has to blow into the tank. Or something. I know I'm being silly but it does seem to negate the exceptionally high level of idealism and usefulness that this project embodies. The energy you'd have to use to fill the CO2 tank does have to be factored in, when you think about it.
