K450 PVC Rocket Engine Design & Construction
In just a few hours, anyone can build a powerful K450 engine that will send a rocket soaring over 5000 feet! Easy to follow step by step instructions and 137 color illustrations demonstrate the exceptionally simple construction process. Best of all, only common materials are used and no special tools are required.
I'd order your copy before the DHS gets wind of this publication.
Addendum: I wish I still had my copy of this book. I had one years ago, but seem to have misplaced it in the various moves since then. The zinc/sulfur formulation that it recommends has fallen from favor in recent years, but it was still an awesome book to have on the shelf.
