Flame explosions (moderate to extreme danger, proceed with care)

Bottle Rocket Mayhem (not for children under 11)

Directions- take apart 10 bottle rockets (if you don't have any, buy some or don't do this) by simply pulling the fuse out (the part you light). Next tap the rocket with a hammer (firmly but not enough to crack it) around 20 times and tip it over into a water bottle cap. The stuff that comes out should be white, after all the white powder (flash powder) has been removed, you will see rusty colored powder start coming out, this is sulfur, don't let much of is get into the cap. Once you have the cap filled, smooth it over and put tape on the top, but make sure the tape is pulled tight. Last, take the fuse from dismantled bottle rocket, and after making a small hole in the tape, insert the fuse. Set it down, light it and GET AWAY! 

 DANGER RATING 7 out of 10

 description: there will be a large flash accompanied with a bang, the more compact, the louder because it is packed tighter, thus, faster ignition. Usually there will be a large plume of smoke, which is general for flash powder.
