Thank you for posting all of these! I used to have the Teleflite book (for making black powder motors), but the fact that the first activity called for was making an explosion shield dampened my enthusiasm for making such motors. The little "mini T-motor-like" sugar rocket motors--and the Microsond 1 rocket--are a different story. Making those little sugar propellant motors in batches, along with the rockets, would be a good enrichment activity for school STEM classes, and:
I know that this contravenes the doctrine of "no mixing of chemicals," but those little motors and their propellant are *not* in the same category as hand-pounded zinc-sulfur motors or stuffing empty CO2 cartridges with match heads. The motors are paper-cased with putty nozzles, and the Microsond 1 rocket is made of paper and wood like most model rockets. The propellant can also be mixed and poured safely in a home kitchen, using ordinary plastic kitchen implements, and the case/nozzle production method lends itself to making the motors in cost-saving batches.
