I'd just buy solid rocket fuel at hobby store. Blackpowder is just going to explode and really not burn.

There are various sites that explain how to build a paper blimp, just scale them up, as far as material goes you need an airtight flexible material that isnt subject to uv attack, mylar is the favorite.

Have you tried the Pressurised Bottle Rocket?\n\nEasily constructed with used plastic bottles. What you need is a pump, cork and a tube. Build some tail fins to stablise the rocket for flight. You need to put in some water in the bottle. Then just pump the pressure up and you have an entertaining setup.\n\nHave a challenge who can shoot the highest and then parachute the Rocket down. The highest and/or the longest hang time wins.\n\nYou will need a field to do this properly though.

When I was a kid, my brother tied pop bottle rockets to a milk crate in an attempt to get to the moon. I was worried that he wouldn't make it in the three seconds before they popped, so I took them all off. You can try it though, it just might work.
