barr

Until now, for my endplugs and nozzles of my rockets and fountains I have been using rammed cat litter which has worked well. However I want to start adding Iron and aluminum to my fountain/rocket mixture to get the spark effect however I have heard that ramming compositions with metal powders can result in friction and sparks that could lead to the device going off. Is there any way to stop this from happening while ramming? what alternitives are there? I know I could press my composition, but how would I achieve adding the end plugs to both ends? or is there a better substiture then cat litter?

Thanks.

I've recently become interested in rocketry and have tried making a few BP rockets and they've gone well, in that they move but i can't seem to get them to go straight.

I've tried adding heavier support sticks and fins but the rocket still falls over and shoots around the ground.

The rockets I have made are: 50mm long, 15mmID

Any help is appreciated.

Thanks
