I did this because it is fun and a cool project to do in school, this was one of my childhood fun toys my dad built and we shot as a kid, I thought it would be fun to re-build so I did and posted a instructible about it.
For this you will need various PVC pipe and cements. I will have to warn you this will shoot far so be carefull.
This is a lot of fun just make Shure that you are at a farm or open field to shoot this
warning: this is dangerous so take caution if you build this.
Disclaimer: if you get hurt in the process of making or firing this device it is not my responsibility.
This can be illegal in your state so make sure to check your state's laws before building .
