put a cherry bomb in it and time it.
Make sure there is no one around you and to stand far back and to make sure it is straight up if not them it will end up flying in a different direction.
I find the best method is to get a 2 liter soda bottle, pour in some normal isopropyl alcohol, coat the insides, and light the back end.
At the center of every rocket is a device called the combustion chamber. Here rocket fuel is mixed and ignited into a controlled explosion. The explosion produces a pressure on the walls of the chamber. There is only one (external) opening to the chamber which opens to the rear of the rocket. Through this opening the exploded products escape, because of this there is no force exerted by the wall of the chamber against the explosion. This means that there is an unopposed force on the opposite end of the chamber - the force that moves the rocket 'forwards'.

The Explosion ended in 2007.
well if the world doesn't end we won't need a rocket so there's your answer
Well, Basically, its a tube with a scope, but with the rocket loaded inside of it, it looks like a tube with glass Coke bottle on the end.
Silent Explosion ended in 1987.
Right, just an illustration. Water is the propelllant that forces to bottle rocket upwards. Imagine a hosepipe. If you hold it in your hand the water trickles out slowly. If you put your finger over the end, a fast an strong spary comes out. This is the result of water pressure. Likewise, if the bottom of the bottle were the same diameter as the rest of the bottle, there would be little pressure, and the water would just fall out. The bottleneck of a bottle acts as a funnel, which increases the pressure and cause water to come out faster and last a little longer. This crests a concentrated upward force which propels the bottle upwards.
Rocket Jets ended in 1997.
Rocket Rods ended in 2000.
Rocket from the Crypt ended in 2005.
