Hopefully there aren't any drafts from the ceiling air vents. Last year at States we were in a huge cafeteria and the ceiling had giant air vents and they were on. We were right under it.

I just wanted to ask if anyone had an idea of what we would need for supplies just to start out with. I know that generally PVC pipe and Wood should be used but what kind and size and if there is anything else that I should get. I know that it all depends on the design but I just need to know how much of what to start out with general designs

Obtaining repeatability is probably the toughest portion of this event. Such as it does not shoot the same cold as it does warm. If you use a piston, does it need frequent lubrication? The 2L bottle does not shoot the same as it is used more.

The 2L bottle is the one where you jump on it, like one of those stomp rockets? Someone used one of those at a competition last year, and it didn't work too well.

"The one where you jump on it" isn't the best description, but I think u got the idea
And yes, that is what retired1 stated

Top team in our state used a bellow last season. I don't know much about their design, but if you understand the design of 2L bottle device, substituting a bellow for the bottle should work...

We went to state with ours, can't remember what we got, we got 2nd at an invitationals. We use like a piston? I think? The one where you drop a weighted pipe down a larger pipe to create air pressure. We got one that was right on the mark, the other was like 3/4 to an inch away from the other point.
