1. Make sure that the bottle cap you have will slide into the film canister. It should slide down freely, but be large enough that it can not flip over sideways while inside the film can.

2. Fill the film canister about 1/4 full with vinegar.

3. Fill the bottle cap with baking soda. Keeping the open end of the cap facing upwards, insert it into the film canister and let it float on the vinegar. The purpose of the bottle cap is to keep the vinegar and baking soda seperate until you’re ready to throw the grenade.

4. Carefully close the film canister so the vinegar doesn’t splash around. (It may be easiest to set it on a flat surface.)

5. Give the grenade a solid toss. As the grenade tumbles, the vinegar will slosh around and mix with the baking soda, quickly creating enough carbon dioxide gas to pop open the film can.

When I was a kid, my friend next door had these little plastic rockets. You put a wad of baking soda, wrapped in tissue, into the base, poured the vinegar in and then jammed the rocket down on the base. Their range was around 20 or 30 feet. They didn't go quite as high as those plastic rockets you would fill half full of water and then hand pump compressed air into them, pull the trigger and whooooooossssssh. What happened to all the great toys? Damn video games.

I first read the title as "How to make a vagina grenade" and HAD to upvote.

I mean seriously, if you had a grenade explode next to you and a bunch of vaginas flew out, would you be able to fight back?

If they put a Mento in that thing, it'd probably take out 3 city blocks.
