8th grade science,we were studying space.Everybody elses were little alka-seltzer rockets with a max height of 20' or balloons(I'm not in a very creative class). Needless to say,I got an A.

Cuz it was actually built for a school project.We had to build a device that would launch a rocket,so I made a stand for it so it stands straight up.But now that the project is over,I might do that.

Have I found any advantages to what?

Here's the T-Cannon specs:

Barrel: 5' long 2" bore
Tank: 5' long 2" wide
Valve: 2" ball valve
