The working model was called "Hot Rod" and was launched in 1959 at
Point Loma California and is now is now in the Smithsonian Air and
Space Museum. It used 6 explosive charges to reach an altitude of
105 meters, the first charge was of black powder but the other 5 were
high explosives, PETN (Pentaerythritol Tetranitrate) .

You can read what George Dyson and his father say about the test flight in
his book, a little is online:
