Thanks, I'm currently working to get a clean ignition on SN3!

One thing that might be happening is it appears you are lighting the mixture on the sealed end of the straw instead of the open end. Normally, packing the mixture tighter will result in a slower burn, not an explosion. Loose material burns faster than packed material because of more surface area exposed to flame. However, that assumes it's burning from open end to closed end. By lighting on the closed end and packing material in tight, there's no way for gases to escape, so pressure builds up until it explodes. It's basically a firecracker at that point. It might be worthwhile to try closing end of straw, packing in powder, then attaching igniter on the open end. Or, doing it same order as you're doing it now, but only close igniter end with wad of paper or paper tape, something that will blow off easily. The gas needs to escape from the end that's burning, which means same end as igniter. Probably won't explode then. Nice work, though. Thanks for the quality videos. Stay safe.

If there's not room at igniter end of straw for escaping gases, you can cut a slit in that end of straw and tape it shut with paper painters tape. That should open up easily once burning starts. Something to consider ...

@@tvinctw6029 Thank you for the detailed explanation! Your point about gas needing an escape route makes a lot of sense. I’ll adjusting the design to allow proper venting! Will implement these changes for SN3 upcoming test.

Use excess aluminum, or add magnesium.
