Stun Grenade

Introduction: Stun Grenade

Parts: (Per Grenade)
(1) 1-1/4" PVC Coupling
(2) 1-14" PVC Plug (not end cap)
(1) 3/4" PVC Plug (not end cap)
(1) 3/4" PVC Coupling
PVC Glue

Parts: (Per Shot)
Baking soda
Baking Soda
Citric Acid Powder

Step 1: Asembly

Dry fit and glue these conections

The 1-1/4" coupling and ONE of the 1-1/4 plugs (do not push this in all the way, just half way)
The 3/4" coupling and the 3/4" plug

Step 2: Loading and Firing

fill the 3/4" plug/coupling assembly with a spoon of baking soda
fill the 1-1/4" plug/coupling assembly with a little vinegar
put the small tube inside the big tube and push the cap on with all your might (do not hammer)

If you are using citric acid powder add 1/4 of a spoon of that to the small tube
and put in water instead of vinegar

Step 3: More

-It would be far more dangerous but you could use flash powder (fire crackers) or gun powder as the propelant.
-It would be even more dangerous if you glued the top cap in place
-I have an a cannon that I shoot these from(

    I thought about youre instructable. And wondered if you put match heads in the cap section.between the cap and the tube. but on the match heads you must put pieces of the 'strike' part thats on the side of the matchbox.Then you must just have like a small hammer inside the tube that hits the match heads into the cap. it will basicly work like a small the ones they use with the clap toy guns. I took a match head once,put it on a hard surface then with the strike section of a matchbox that I have cut off.The strike is usually brown colour.the strike side must lay on the match head.then you hit the whole thing with a hammer.and BANG!
    Just thought of sharing the idea. I love grenades and bombs etc.

    I like the design of the grenade you have here, though I would like to post a modded version of yours that would be safer to use flash/black powder in since I don't think baking soda and vinegar would produce that much of a "bang" and certianly no flash... I love the fact that it fits in your potato cannon :D What diameter barrel do you have?
