coke bottle hybrid rocket engine

[RamboNucke]

We all sprayed deodorants in coke bottles with hole in the cap and ignite and watch it fly. But making it a light weight hybrid rocket can be almost just as easy. The thing didn't have a nozzle, it was just to test how will it ignite and behave.

Needs to be pointed up and finned

Worried about law enforcement or is there a chance you might actually make one fly in daylight?

I'm noob in rockets, making something fly is easy, but making it fly in a certain direction is another story. It's night time because I was bored when it was dark already. I planned testing it in the kitchen, but I decided to use bigger bottle, more pressure and went outside.
