[sdiy] DIY rocketry

[Rob B]

I have been hearing that purified H202 is really cool and safe, save from
the fact that you could at least physically blow yourself apart.. At least
the pieces will stay uncharred iirc.. ;)

h2o2 and a platinum mesh.. Hydrogen Peroxide... Mostly stable and safe
compared to the *good* stuff like Unimetyhl Dihydrazine and Inhibited Red
Fuming Nitric Acid..Since, if you can smell that stuff, you are usually
already dead.  Leaves a hell of a mess too..

Pressurized CO2 cartridges can be made into fun and relatively safe
engines...I have heard that there are some liquid nitrogen engines being
worked on too, for model jets and rockets..

Ahh, the good ol days of working on a ballistics range, testing all things
that go boom or whoosh.. hehe..
