Just because it has a gauge and uses compressed air doesn't mean it's a cannon, guys.

I'm not sure if a bottle rocket is a cannon or not seeing as it's self-propelled. It would more class as a rocket then a cannon, so I was right.

That launcher is a step above what my friend made -- that's a nice release system. When I used my friend's launcher, it would just shower me with water. :)

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?

With the pulleys and rope, I imagine he yanks on the rope to pull down that release valve (like a quick-connect for garden hoses) and the pressure launches the water bottle up.

At least you can do it from a distance with that :)
