Picture of How to make a baking soda and vinegar rocket
Just recently I bought the Cosmic rocket.It was a mistake.The tube that contained the baking soda and vinegar was so tight that the rocket could not build up enough pressure to take off.It had a good system for launching but it was so tight that only if you put it on lightly could it take off.After I returned it I began to think.I wondered if I could rig up a release like that.I found that 1/2 PVC fit perfectly in the neck of a 1 liter bottle.So this ible was born.I am entering in the epilog contest because it is using a bottle that would other wise be thrown out.I have entered it in a contest so please rate or vote.

Step 1: Materials

The materials...
1/2 PVC,at least on inch.In the picture I used to much.
wood.Foam would work better but wood is what I had.
1 liter bottle.
hot glue gun.(any kind of glue will do)
baking soda
vinegar.
Thats it!

Fill 1/4 a bottle with vinegar, put 2 tbsp baking soda on a tissue poke in the tissue so it doesnt touch the vinegar, leave some tissue out then put on the cap over a piece of the tissue so it doesnt fall in the vinegar, lastly, tape around the cap so it doesnt release pressure.. THROW IT! *this is for 16 oz meyer grey bottle*

》you can cut down size for smaller sizes《

Hmmm, Having just built one, to these specs. I'm sorry to report that it doesn't work. Since you posted it here, I'm assuming you actually got this to fly... Did you perhaps forget some critical launch or construction tip?

Now I have added a video.

It doesn't work?!I got mine to fly right.What bottle are you using?How big of a piece of pipe did you use?What did you make the base from?And,why doesn't it work?Like,it doesn't take off or there's too much leaking around the bottle?Or,if you could post a picture that would help.

Cool!I had never thought of using 1/2 inch pipe instead of a rubber stopper or cork. P.S.Favorited.
