Airsoft Grenade




About: I like fun stuff, deadly weapons and non deadly weapons, that should explain all you need to know.

Intro: Airsoft Grenade

Hi, this is my first Instructable and it is a fairly simple recipe for making an air soft grenade, you will need: Baking soda, Vinegar, a Ziploc bag, scissors, a spoon, air soft bbs(optional) and a water bottle preferably a thin one such as crystal geyser or nestle pure life, also I recommend eye protection.

* Please note i am not responsible for you or your actions, if you hurt yourself or others don't blame me.*

Step 1: Materials

Any type of vinegar should do, i recommend a thin plastic water bottle such as Crystal Geyser or Nestle pure life bottles.

Step 2:

First empty your water bottle, by either drinking it, Yea, or dumping it out on the ground, no. Then insert as many bbs as you want. then mark about half way up your bottle and fill it with vinegar to your mark.

Step 3:

Next cut the zipper off your plastic bag, then carefully take the bag, not the zipper, and insert it into your water bottle of vinegar but not all the way leave the opening to the bag and stretch it over the side of the water bottle, do not let the bag fall in!

Step 4:

Next put your baking soda into the bag using your spoon, i recommend 6 or 7 spoon fulls of baking soda, now is the most crucial part so do not let your bag fall in.

Step 5:

Next screw on your cap over a slim part of the bag for transporting small distances, if you are going to be running long distances i do not recommend leaving the bag in the bottle but instead inserting it when you are ready to use the grenade.

Step 6: Using Your Grenade

First put on your eye protection! Then to prime your grenade simply unscrew the cap and push the plastic bag into the bottle, then screw the cap back on tightly and shake the bottle a few times then throw it, it works best if you throw it against something hard, if it does not go off right away it will go off but it might take a while. I will be uploading a video of the grenade being used soon.
Like i said early this is my first instructable so if its awesome leave a comment if not i don't care.

Try using 2 cups of hydrogen peroxide and a teaspoon of dry baking yeast instead of vinegar and baking soda. the bottles ALWAYS explode without needing to throw it, and if you shake it well it takes about a minute for it to explode (ive also heard that hydrogen peroxide and bleach works faster than yeast, i havnt tried it)

This is a great idea, but I can just imagine someone carrying these around, then getting hit in the back and them all going off because they mix. Would be really funny to see, but would be a really bad day for whoever it happened to. Other than that, this really is a good idea for an airsoft granade, and i'll have to try it.

I made one and threw it at my friend cuz he was charging me and it hit him in the face then went off XD ,Then he shot me in the neck at like 25 ft. But it works well

I have used this grenade before and it is a great idea but it hardly ever works for me:( the only time it did work was when it was in my hand lol.

Awsome job! I have been experimenting with conifer and bakeing soda for a little while. And did not get the bottle to explode yet. Just the cap came of. How do I get the bottle to actually breach and explode?

What is the fps. I'm not sure about it but that grenade looks pretty good. I'll try to build it.

i do that and you want less vinegar and more baking soda

I tried one of those bottles but the plastic is too thick as it has to hold the carbonated soda in and so the bomb does not explode.

Tip for the close shots- if it has a "macro" setting (my camera has a flower-looking symbol denoting such), it takes much sharper close-ups. jtlyk.

BTW, i was wondering a good way to do this.... Now that someone else figgured it out, i dont have to, though! how far do the BB's fly?

A good distance, I've never really put very many bbs in because I never see them go flying but when I go to look at the bottles remains theres honly a few bbs left there.
P.S. Thanks for the camera tip.

Np, thanks for the 'ible. now that school's almost done for the year, I need a good arsenal to complement the CO2 Mac-11. Came back to re-find all the awesome ideas everyone has.
