This rocket is propelled by the sudden release of pressurized air, so all the parts need to come together with tight seals to hold the pressure in until you're ready to launch. PVC Plumbing pipe won't leak as long as you use the right kind of pipe cement and make sure to clean all the connections before gluing them.
A simple string-controlled trigger unlocks the pipe from the end of the bottle, releasing the pressure and sending the bottle into the sky.
1. Cut the pipe
Using the hacksaw, cut three lengths of ½-inch PVC pipe: 2 inches, 18 inches, and 78 inches.
2. Drill a hole for the valve
Using the drill/driver fitted with a ½-inch bit, make a hole in the top of one of the PVC end caps. Hold the cap steady with pliers as you work, and make sure to drill straight down into a piece of scrap wood.
3. Connect the valve
Remove the small cap from the tire valve and set it aside. Slide the valve through the hole in the PVC end cap so that it sticks out the top. Screw the valve cap back on. Grab the end of the valve with pliers and pull it until it's firmly seated in the PVC end cap.
4. Glue the launcher parts together
Line up the pipe sections and connectors in the order in which they will be assembled: solid end cap, 18-inch piece, tee, 78-inch piece, and the 2-inch piece connected to the leg of the tee.
Using PVC pipe cleaner, clean both parts of each connection: the outside of the pipe and the inside of the fitting. One by one, glue the connections together with PVC pipe cement, holding the parts together for a few seconds as the cement sets.
NOTE: Always work in a well-ventilated area when working with pipe cement.
5. Make a seal for the bottle
Mark the pipe assembly 11 inches from the long open end. Using the flame of a birthday candle, heat the pipe evenly at this mark until it becomes soft. Then push the pipe inward to create a slight bulge. Hold the pipe straight until it has cooled and the bulge is no longer soft. This bulge will create a seal between the pipe and the soda bottle.
6. Build a clamp for the bottle
Using duct tape, tape nine cable ties together so that they all face in the same direction. Make sure the cable ties are parallel and their heads are lined up evenly. Tape over both sides so that no adhesive is showing.
Slide a soda bottle over the end of the pipe and seat it against the bulge. Wrap the cable ties around the pipe so that the head of each tie faces inward and catches the lip of the bottle, holding the bottle tight to the bulge. Secure the cable ties in this position by tightening the hose clamp around the duct tape.
7. Make a launch trigger
Using scissors, cut the top and bottom off a 2-liter soda bottle. Flatten the bottle section without creasing it and cut a 1¼-inch hole through both sides. This spring will hold the trigger in position until you're ready to launch.
Drill a small hole in the side of a short scrap of 1½-inch PVC pipe. Thread the end of a 4-foot piece of string through the hole and tie a knot on it to keep it from coming out. This pipe is the trigger.
Remove the bottle from the end of the pipe. Slide the plastic spring onto the pipe, over the cable ties, and up against the pipe clamp. Then slide the 1½-inch PVC scrap over the pipe and cable ties. Thread the string through the holes in the plastic spring. Tape the other end of the string securely to the pipe with duct tape.
Test this trigger mechanism by pulling on the string. The PVC trigger should drop, allowing the cable ties to open up. When you let go of the string, the spring should push the trigger up and over the cable tie ends.
8. Prepare for launch
Fill a 2-liter bottle about one-third full of water and slide it onto the end of the pipe. Pull the string on the trigger down so that the bottle can seat against the bulge and the cable ties can catch the bottle's lip. Release the string and let the trigger slide back over the cable ties to hold the bottle in place.
9. Pressurize the launcher
Attach a bicycle pump to the valve coming out of the tee. Pump no more than 70 psi into the launcher.
10. Launch the rocket
Make sure the launcher is pointed straight up and that there is adult supervision for every launch. Count down, pull the string, and blast off!

How did the rocket burst in which kalpana chawla traveled?
when they were taking off from earth to go to space one tile of rocket get off and when they were coming it takes more force and because of the tile the rocket burst
When was the first rocket to go into space?
It was a German rocket in 1944.
How is a real rocket able to blast into space?
the pressure from the the rocket's fuel thingy makes the rocket go up. pretty soon, the rocket is in space.
What does a gyroscope do for a rocket?
A gyroscope will use the principle of angular momentum to do one or both of two things for a rocket. 1. Stabilize the rocket in terms of pitch, thereby limiting the amount of fin surface area that is required. 2. Minimize roll, allowing the rocket to go higher and faster.
How much air pressure does it take to launch a water rocket?
the best psi for launching a bottle rocket high is 65 psi because usually you want it to go high without a big chance of exploding in you face
Does a smaller water rocket go higher than a bigger one?
yes because a heavy rocket will not go high yes because a heavy rocket will not go high
How do you get the key?
to get the key you have to go down the rocket with WATER !
Does water rocket go higher with more or less water?
use your head
How do you think your bottle rocket will fly?
by water being placed into the bottle and then, when you launch your rocket, the rocket will spin (if it has at least 2 fins) and the water will spurt out and make the rocket go higher in the air. (Tip:the more it spins,the higher it will fly)
What is the right amount of water to put in a bottle rocket so it will go high?
the right amount of water to put in a bottle rocket so it will fly high is 70 milliliters
How do you get a-team-rocket-uniform?
Go on eBay to get a fake one and die
How do you go in the rocket on Pokemon Emerald?
Fly to mossdeep city in Pokemon emerald version then go to the space centre there will be two proffessors one will say what 99%..... and one will say Rocket Launched Succesful No.__
Where is team rocket in ice cave?
first u enter ice fall cave then u go find HM water fall (its in ice fall cave ) the u go up water fall keep going u'll see team rocket
Will adjusting the amount of water used affect the maximum time the rocket will remain in the air?
Yes, in a sense. In a water rocket, the water is reaction mass. That is the water expelled from the nozzle on the bottom pushes the rocket in the opposite direction. The more reaction mass expelled, the higher the rocket will go. From practical experience, however, you'll find that there is a tipping point. What I mean by this is that there will be a point when too much water will be too heavy, and the rocket will not be able to hold the pressure (water cannot be compressed, so some airspace is necessary), and will not gain much if any altitude.
Do you need a small rocket or big rocket to go to Mars?
big rocket
How do you go to the Raz Rocket in Raz Kids?
So you go to your Avatar and where it says Raz Rocket, you press on it and then you are on Raz Rocket.
How do you defeat team rocket in soul sliver?
After you get the ragecandybar you go to the radio station. Team rocket won't let you in. So you go to the underground path in Goldenrod and go to the place that you can get your picture taken in a team rocket suit. A team rocket grunt will give you one. Go back to the radio station and battle the team rocket grunt at the stairs. Then go up to the manager's room you battle a team rocket leader there. Then rescue the manager at the bottom of the underground path. Go back and enter into the locked door in the radio station/tower and go until you find a room with one person looking out of a window. He is the final team rocket leader to beat and after you beat him he says that he will disband team rocket. Then you can go past the man who gave you the ragecandybar. Check the first guide for further details
