I'd draw one up but i dont have access to a scanner, so check some of the notes in the resources section: http://www.boredofstudies.org/view.php?course=11
We had a side arm flask with glucose, yeast and salt. The arm was put into a test tube containing lime water then the top blocked with cotton wool.

You should've asked me at school...

Yeast + sugar + salt in the conical flask with stopper + glass tube + rubber tube which is connected to a glass tube with a stopper on top of the Buchner flask containing the calcium hydroxide solution.
