Introduction: Launching Rockets

 We designed rockets, candy rockets. It was a process that took some time. We had different techniques, depending on the group. One of the groups did 50/50 and the other did 60, stump remover and the other was sugar. We would make sure we had the right amount and then we mixed them well together, transfering it from cup to cup. After we did that we grinded it up until it was a mix. Once that was done we put it into the moder. We put a small amount in and then we would pound it in to make it compact. Once that was complete we nailed a hole in the bottom. Once that was complete it was time to launch the rocket. From our experience it seemed that the 60/40 was more succeful. Other groups cooked their items and also boiled it to get all the water particles out and did the same things, by compacting the materials into the moder. Using rust seemed to make the rockets more powerful and were able to launch better. Many of the rockets were to powerful and seemed to be more like a bomb, not a rocket. We had to find a median between the two.

Safety note: grinding this mixture in a pestle and mortar can generate enough heat to ignite it. I know of at least one case where this procedure cost a student fingers when a batch exploded in the mortar during grinding.

Judging by the sudden rush of rocket-fuel instructables, it looks like a class are all posting their work. Could you do me a favour, and ask the class teacher or group leader to contact me?

They can reply to any of my comments on these projects, but it would probably be better if they send me a PM.
