Ok this is probably a silly question but oh well. Where do you get the right fittings? I'm guessing you just have to look harder because the ones I used were right by the pipe.

Thanks I will do that.

I'll try to. Live and learn

Alright thanks I will scrap this one and build a new one.

Well never mind this is getting scraped asap lol

I have a combustion cannon that I power with aqua net blue hair spray. Are there any other hair sprays that work well? Also is there anything else besides hair spray I could use for fuel? Thanks

Thanks everyone for the info. For now I am just going to use a cannon that runs off hair spray even though it will be unreliable because I have to demo my concept on Friday. The good thing is that my teacher said that as the project progresses changes can be made to it. Since a lot of you ...

Hi everyone I want to make a potato cannon for my chemistry project. My teacher doesn't care if it is a pneumatic or combustion cannon just as long as I can to multiple tests fairly fast. So I wanted to know the pros and cons of each type so I can figure what type I'll be building. Thanks so much.
