Homebrew PCBs

My Dad worked for Bell Helicopter when Bell Aerospace came out with
the initial 'rocket belt'.  If I remember right it was propelled by a little
bit of
compressed nitrogen pushing H2O2 out of the 'jet' nozzles where it was
pressed through some platinum screen that caused the H2O2 to disassociate
into H2O and H2 along with enough heat to ensure the water was flashed into
steam.
