    What would be the cost of making this project. Is it worth making it for a school project?

    Danger: See link: This is not spam, but a warning. PVC will fail suddenly after a while. This was band member that hurt badly by a T-Shirt launcher explosion.

    See the pictures and never use PVC to hold air, Please.

    Dude DO NOT PUT THE propellent IN FIRST .You could nudge the ignition while trying to get a spud in and BYE BYE HAND thats rally dangerous. plz for your own safety put the propellent in last .

    So many safety issues! And it was kind of a weak launch...

    Though you wont get nearly as much power by putting in the propellant last.

    Hahahahahaha George Bush

    Whats the farthest launch you've had

    Please Friend! I beg you to tell me how to create the spark ignitor you created. I could'nt figure it out. Please I' m in a desperate need for such a great one. Science fair is near and i don't know a way to create an eco-friendly ignitor like yours

    just a tip never combine whit pvc and black pvc it could end up being faulty and u might blow your face off just incase you didnt know the the two dont stick

    DO NOT ,I repeat, DO NOT EVER PUT YOUR IGNITOR ON THE END CAP! This is for two reasons One, It weakens the integrity of the end cap Two, If you drop the gun on its end , it may fire accidentaly!
