--END TRANSMISSION--

just attach an engine to it! its tat easy.

simple.....water and compressed air...look it up on www...called a bottle rocket

Why bother making a crappy one yourself? You'll probably just blow your hand off. Go to a store and buy some real ones.

make plastic wings, put baking soda in three tissues and place it in the bottle(the tissues will create a delay) add vinegar, shake place on ground and back away

In 4th grade we did this and we used a 2-liter bottle for pop cleaned out, put water in half way and a chemical - forget which one and then used a hose to launch it in the air. Good luck! Wish I could have helped more.

They sell kits with a pump, fin kit and nozzle that you use, you fill the bottle partially with water, then connect the nozzle and begin to pump, when the pressure gets to a certain point it blasts off and, god do those things go high. Here is a link to the kits. http://cgi.ebay.com/HYDROFLITE-Air-or-Wa...
Pretty cheap, only $18 shipped. Well worth it.
Also here is another, it's a bit more money but you can use just any bicycle pump. http://cgi.ebay.com/ROKIT-Air-water-powe...

Homeland Security would love to get a hold of you. Explosives and or devices thereof ARE STRICTLY CONTROLLED ! Also if you do not know what you are doing LEAVE IT ALONE ! Fooling around with this type of mat'l can and does cause injury and at times DEATH ! Ever heard of BATF ? They monitor these sites. This is no joke amigo, The fellas' in the "black suits " ARE FOR REAL !! 30E.O.T.)

Materials:
In order to build a bottle rocket several items must be acquired. The most important item is a two-liter soda bottle. Just go to a store and buy any brand soda that you want, or better yet, the bottle that looks the best to you. This soda bottle will serve as the body of the rocket. You will also need a piece of 3/32" balsa wood for the fins. Other materials include a rubber based cement and a manila folder is needed for the nose cone. You are now ready to construct your bottle rocket
1/ To fly the rocket, you are going to have to put water into the bottle so it will work properly. After putting some water (2 - 3 cups) into the bottle, place it onto the launch pad and slide the pull pin over the flanges on the nozzle. Then, Turn on the air compressor and pressurize the rocket. For the first flight, we recommend that you only pressurize to about 45 psi (pounds per square inch). After the first flight, we recommend that you do not go past 75 psi, otherwise you may risk the possibility of the bottle exploding. 75 psi will make the bottle rocket fly very high and very fast.
