The one with the Physics Project

Hey people, so I think we are sticking to the steam engine unless anybody objects.
The most basic example which I found is http://www.youtube.com/watch?v=FwOIL74yrCU
Many more can be found if you search " Homemade steam engine" in Youtube.com
I have asked Pn.Madihah ( Hopefully that's her name ) and she suggested to present the even if it doesn't work ( as a static model )
So our biggest problem right now is the materials.
The following are the items I have found over the past few days :
1) A wooden base for the project
2) A bicycle pump as the piston
3) A pipe for the steam transmission
4) A boiler made out of a Milo can

What we need are anything that are not stated above. Please try searching for them.
May I suggest we meet up on monday at 9 to discuss about the theory and progress?
Text me if you have any ideas or can't make it on monday.
Thanks people!
