Signing UpStep 1: Get the Materials
In order to build this cool rocket, you'll probably have everything you need at home. These are the materials you need.
Materials:
2 2-litter pop bottles- You can use any size, just make sure both are the same size, though. I like 2-litters best because they go the highest. Try experimenting with different sizes.
Duct tape- The ultimate tape.
Hot glue gun with glue for it
Cardboard- Find the sturdiest.
X-Acto knife
After you get the hot glue gun, you should probably plug it in. This way it's hot when you're ready to use it.

a estes model rocket launch pad works great for these just glue a pc of straw on the side. i made one with 20 oz. bottles and used this method. me and my 2 boys are making one from a 5 gallon water jug now to try.

in reply to Aug 18, 2009. 8:18 AMReplyOh, I see. Nice idea. A while back I tried to make one and the hot glue melted and disfigured the plastic. But my glue gun is a high-heat glue gun. I figured I'd eventually buy a low-heat glue gun and try again. Maybe we'll test the high-heat glue gun with the duct tape to see if that will protect the plastic. Thanks for a simple and straightforward Instructable.

I have made some of these but smaller out of little water bottles and a tiny pump. I put a hole large enough for the hose to go through in the bottle cap and filled the bottle 1/4 way with water. I then put the hose into the hole (which had a tight fit) and started pumping. After the bottle was presurized (feel that it is hard to squeeze) I placed it so that the water was at the end with the hole in it and pulled out the hose (you better be wearing water-proof clothing.) The rocket shot into the air! If you have a question ask me!

THIS is kewl. I get to make one for a school project, and I was wondering if any of you know a way to make them whistle as they fly. I am kinda thinking of whistling arrowheads from China. I think a simple hole in the side of the nosecone should work, but I'm not sure. If anyone has ideas please reply?

Cool!Just tried my version.I didn't do it with water though.And I only put it up to 50 psi.But it was snowing and it was hard to pump.Also I didn't feel like getting blasted by water in the dead of winter.

I was thinking about making a smaller one of these with water bottles or soda bottles or something and then having a launcher that was shoulder mounted like a bazooka. I would make it for an air compressor though so it would fill quickly.
