this is my first instructable so bare with me on this. in this instructable we will be making an airsoft grenade and pull pin igniter out of normal household junk (and some not so junk.) it didnt cost me anything and im 12 so once again bare with me on this. ALWAYS have a lighter or matches if the pin is a dud. and dont forget to throw it. The fuse might be different lengths, too.
Step 1: Materials
Your grenade will need:
-scissors (i used the scissors on my multitool)
-tape (anykind will do but i used scotch)
-ruler (on my multitool, too)
-firecracker (i used a bottle rocket but it explodes)
your pin igniter will need:
-paper clip (mine are funky but you just gotta bend normal ones)
-matchbook sandpaper stuff (or fine sandpaper)
- tape (or a rubberband)
Step 2: The Body
what you'll do is cut the newspaper into a 6"x3" rectangle ( or bigger- depending on your firecracker and how many bb's you want to pelt your buds.) Tape the sides together and put tape on the bottom (only if you have a bottle rocket engine though.)
Step 3: Adding the Charge
If you have a bottle rocket rip off the engine first. Simply tape the explosive inside the the body so the bottom of the explosive is about 3/4 from the bottom of the body.
Step 4: Adding the Bbs
Its pretty self explanitory but fill the body about half way full of bbs.
Step 5: Tape the Top
Pretty self explanitory ;)
p.s. don't tape over the wick
Step 6: PIN IGNITER :)
-cut the sandpaper off the matchbook
-fold it like the picture
-tape it to the paperclip
-tape the match to the newspaper but make sure the match is pressing against the wick
-tape the sandpaper around the match
Step 7: And Walah
now all you gotta is yank the pin off and see if it lights but throw it, too. If it doesn't light you should have a flick lighter or something else.
