Yeah I usually take the rockets to about 120 - 135 psi.
So about 50 - 80 psi wont hurt. I could just switch out the bottle every now and then to be safe.

Take a picture of it...lol...I want to see.

Also, Tail? What kind of tail?

Those waterbottle Rockets are fun...and mostly safe...lol

Have you gotton it yet? or even tried?

lol, Zip-Ties always work wonders.

lol.

How would you hold the screen tight?

Thats what I was thinking. Because when I do "The Works" Bombs and stuff. Too make a Louder noise I wrap it in tape and it Strengthens the bottle which allows more pressure to build up, resulting in an un-normaly loud noise.

Without getting PVC what could I use as a decent Chamber?

I can go 50 safe right?

lol, nice.

lol, yeah.

I watched mythbusters and they said a certain psi but I forgot what it was.


Also, it is a 1 inch barrel. Any ideas for ammo?



P.S.
To everyone who doesnt remember me.
Its not my first cannon.

My question is, How many psi can a 2liter bottle hold?



I have a bike Tire valve on a 2liter bottle, then the 2liter has a barrel on it.
