Step 5Launch That Puppy
To launch, simply close the quarter turn valve, fill the air tank with compressed air, put your rocket on, open the valve and, POW! there goes the rocket.
I use an air compressor to fill the air tank, but a bike pump would work. Slowly.
With the smaller rockets, it doesn't help to put more than 80 psi in the air tank. And at 60 psi, you get 90% of the hight.
Some thing to note:
Don't stand over the rocket when air is in the tank. These thing move. this is similar to a spud gun, and it will hurt to get hit at point blank. Bad.
It is loud. Keep your head away from the end of the launch pipe. It may piss off you neighbors. Don't blame me.
DO NOT try and catch a rocket on the way down. They are going almost as fast as they went up. It stings if you do catch it, and you really don't want to catch one on the head.
In spite of those warning, the small ones really aren't that dangerous, and won't damage anything. I make them with my Webelos, and so far the only harm happened when one of them tried to catch "The Big One" I made out of a full sheet of poster board, a Nerf ball and some coroplast (Corrugated plastic, like cardboard but made from sheet plastic. Think political lawn signs). And all the happened to him was a scrape from the coroplast.
They will bounce when they hit the ground.
Other than that, have fun. I look forward to your comments.
