Did you post how to do that in the kitchen science or did I miss it??
I haven't put it on the main site, but I have written one here in the past:http://www.chaosscience.org.uk/pub/public_html//article.php?story=20050605135858118If you can get hold of a rubber bung it works better.if you make the hole smaller - by epoxing a smaller diameter pipe through a hole in the lid it will go a lot better, especially if you run it purely on air without the water.
I think that a bottle will work far better. Lemonade bottles will hold huge pressures for their weight, I think they are designed not to fail at 5 atmospheres, and generally don't fail until 8-9. unless you are using some pretty fancy foam you won't be able to hold much pressure at all, and because the energy stored in compressed air goes as the square of the pressure, it won't go ver well.
