Great,you are ready for launching.Put some vinegar in the rocket.Put some baking soda in the piece of pipe.Now,get yourself outside.Attach the 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.
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!
Step 2: Building the launch pad.
Now,take your 1/2 inch and cut off a 1 to 2 inch piece.If you are using wood for the base then drill a hole the size of the pipe in it.With foam simply shove the pipe into the foam till it sticks firmly.Then,glue around the bottle until there are no leaks.To make sure there are no leaks blow into the top and seal any leaks with hot glue...lots of it.You just built the launcher!
Step 3: The rocket
Okay,to build the rocket you will need the bottle.You can just use the bottle but take a look at the rocket below.
