PS: I still have the scar on my hand from where I was burned by trying to handle the Jetex carcass shortly after an engine test burn... the engine being held in the jaws of a pair of pliers! I somehow doubt that kids of today would be allowed to purchase anything even remotely similar to Jetex pellets!
That does seem a little incompatible with modern health and safety thinking. And I happen to know that real ICI manufactured Jetex manufacture ceased about 50 years ago, although there have been various relaunch (in the marketing sense) attempts.
Today the closest you'll get to an authentic Jetex experience is via the Czech made Rapier units. These and suitable kits can be sourced from
SAMS Models Section F. Motors. Rubber, Co2, Electric
Scroll down the page and you'll see something called Jet-X, avoid.
Scroll past it to Rapier...
See elsewhere on the site for various stick and tissue types, including
Then a trip to Cosford, or the Deutsche Museum in Munich to view the fullsize, just to get the details right, doncha know...
