You can tell how awesome a cannon is by the pressure used.

look closely at the pictures .... you will see that....
A.
the pulley system for the rope.. you want to hook like a leash or something at the front where the rope makes a u between the two eye hooks
B.
you can see how it connects to the quick connect.. by the means of a hose clamp.. this way when you pull on the rope.. FIGURE A
you will put equal pressure on it.. making it pull down and release the rocket.

he asked how old i thought he was...spudchucker wrote:It's pretty simple the little weight that is on the nose cone keeps moving up off of the rocket when the rocket reaches apogee it's max. hight.
Ex. putting a penny on your hand and jerking your hand up same principal the penny will lift off of your hand.
Can you tell me how old you think I am?

yep I'm 13 well anyways the reason why I have a large rocket volume is that the more air and water you use the higher the rockets goes
My rocket 4 litres air 2 litres water IT'll go higher
