  • hollow core? thats a new expression to me,nice engines tho, i liked that header with the whistle +a liltle tip,try making parachute,ramm bp+ti orsomething that sparklers and add the chute to the tube,its a nice effect

  • Did u rammed it?

    Because it could explode when u ram it!

  • end burners or core burners?

  • how did you make them?

  • Well, black powder chemicals... I don't think it's granulated.

  • Huuuuuuuuuuuuuu!

    Nice, the motor is the black powder, realy,only???

    NICE!

  • Yeah i guess, last time i used my caps for my tubes(i hot glued them in) it just blew the cap right off and we didnt get a bang :( ...but im going to try ur way next time :) ty

  • That would compress the FP, which works best when the chamber is only about 60% full as the reaction only heats the air around it, and doesn't produce gases like other explosives.

    Also, clay just isn't needed - cardboard is grand for a loud report if your FP is strong enough... and also you wont get a supersonic lump of clay in a spectator's face :).

  • well u should put some clay over the FP because it will most likely blow the card board right off, but make sure not to ram the clay because it may ignite the FP from friction. Instead put some body weight on the dowel to make a plug, then if u can put a cap on the end.

  • cool. those are fireworks rockets....instead the other youtubecrap!...sweet vid
