BLUE STROBE ROCKETS. Join Bill "Doc" Barr in a tour of making blue strobe rockets. Ever seen Doc's Blue Whizzees? You gotta see 'em to believe 'em. He shows the correct method to make a nozzle, including the correct pounding technique. The comp. is spongy - there are air bubbles and such. How can you press this stuff? How do you keep it from oozing around the rammer? Doc tells all. Complete with formulas, techniques and tons of hints, tips and tooling! Watch a skillful craftsman show his way of producing successful rockets.
