Vinegar Grenade

You can probably find all of the materials for this simple project in your house. When you make one of these and throw it in the air, it will explode mid-flight. The principle of this project is the same as the dry ice bomb (squeezing too much gas into too small a container). Carbon dioxide gas forms as the result of a chemical reaction between the vinegar and baking soda. This project is safer than the dry ice bombs because the explosion is much weaker, but you should still be careful and avoid getting the chemicals near your face.

   Here’s an idea, instead of using a separate cap to hold the baking soda. if you wet the baking soda with a little water to make a thick paste, you can fill the depression inside the cover of the film canister with the baking soda. you do need the white canisters like in your illustration, but they work wonderfully.

    if you want to secure the top and make the canister explode, buy the film canisters with screw on lids. dunno how rare they are in other places, but they are easy to find where i live. for really good, mess, and staining action, get ahold of a plastic connical flash and a cork. add the viniger and bakingsoda but drop in some red food dye before the shake. aim and have fun

    I used to do this, but I would place a piece of tape halfway down the film canister to make a little shelf (kind of forming a U shape with the two sides of the U adhered to the sides of the cannister and the bottom spanning the diameter of the cannister). Below the tape shelf I poured the vinegar, and above it I rested baking soda wrapped in some tissue paper. The tissue paper worked perfectly as a time-delay because it would take a few seconds for the vinegar to permeate the paper and reach the baking soda. I also used to play with these outside, and then when my Dad noticed the series of brown spots on the lawn where the acidic mixture had killed the grass he wasn’t too happy with my awesome grenades.

    for a bigger bomb use a water bottle, tissue paper,vinegar,baking soda,and clear tape.Fill up the empty water bottle about 75% full with vinegar then take the tissue paper and lay it flat and put about 4 table spoons of baking soda in the middle and roll it up and cover it all with clear tape exept for one small dot about the size of a pencil eraser. when u want to use ur grenade poke a hole in the packet of baking soda on the uncovered spot completly open the spot up and quickly put into the bottle screw on the cap, shake the bottle until u feel the bottle getting hard then throw it against a solid hard flat surface that u dont care about.

    Since it’s hard to seal the film canister well, I suggest using those half pint Poland Spring bottles. Add 1/3 the bottle of vinegar and wrap a reasonable amount of baking soda in plastic wrap so it will fit in the bottle. Put the wrap in the bottle, go out side and shake ALOT. Slam with all your might the bottle onto the pavement or hard surface (NOT IN YOUR HOUSE) and BOOM. =] Film canisters really sucked.

    Mr. Cool kid, thats kinda what ive been getting at for the last posts… Except the ammount of kleenex tissues you need for the baking soda to be dry, clogs the hole, or is generally a big waste of kleenex tissues. A thin layer of plastic wrap about 4″ by 8″ gets the job done. One Layer too!

    for more fun. make a vinegar cannon. take an empty water bottle and fill 1/4 with vinegar. then fill a file canister with baking soda. quickly dump the baking soda into the water bottle and have someone to twist on the cap. drop the bottle. it will expand. now you need to hold the bottle with your foot. then carefully with the other foot. work off the cap with 2 strokes. then kick off the cap with one big kick. it will shoot the cap and foamy mixture. also you can fill the bottle with airsoft bb’s or a small paintball.

    We used to do this as kids too, but we’d put a little pile of baking soda in the center of a piece of toilet paper, then wrap it up and twist it shut. We’d then screw the cap on a bottle or stuff a cork in so that the twisted part of the baking soda bundle was held inside the bottle, near the top-where there is no vinegar. When you want to pop the container, shoot the cork, whatever, you just tilt the bottle so the toilet paper dissolves in the vinegar.

It was standing upright, he was standing right over it, and as soon as he brought the stick back to smack it, the lid blew off and knocked his baseball cap off his head and there was a massive 30 foot geyser-canopy of vinegar that soaked him outright. Vinegar-fizzed in the face; he was so shocked he didn’t move until a few seconds after all the projectile vinegar fizz landeded.

    What I did was put vinegar in a water bottle and then put a plastic bag in the bottle and put baking soda in the bag then took a knife and cut holes in the bag and then tighten the cap and shook it then rolled it and 5 to 15 sec. later it went boom and blew a hole though the cap and a hole though the bottom. p.s. It also works with a power aid bottle.
    p.s.s to make a air soft grenade just add bb’s to the vinegar and baking soda.

    Break the dry ice into tiny little pieces with the hammer (best way ive found, put a plastic bag over the dry ice in a tray and beat it with the hammer).

    Put the pieces into what ever plastic bottles you have. right at abt 1/4 does more then enough. Pour hot water in the bottle and cap it. Throw it as it expands. The more ice thats in there the longer it takes.

     get a can of hairspraY and build a fire and thro it in the fire. get out of there quick unless u want to get burnt to death or lose a limb. a propane tank (like the ones for grills) will work also, but u will need a car handy for that. (I wouldn’t use a propane tank if I were u lol)

     if you want a cooler bang, get some liquid plumber, some bottles, and some aluminum foil. put a bunch of foil in the bottle, the more surface area the better. then put liquid plumber in and quickly tie on cap and throw. dont forget to shake.

     Place backing soda in small Ziploc baggie (a small for coins) fill it up and zip it closed. Place it inside a big Ziploc bag add ¼ cup of vinegar (look for the higher acid content, most is 5%) zip the bag closed. It should look sort of flat like a mini pillow with a fat little pillow inside. There should be enough room for the bag to swell twice its size. Add some sulfur dioxide if you are making a stink bomb. Carefully open the inner bag through the big one and it will expand and pop making a mess.
     Sorry, no boom but you can make many and carry them around for your “wars”.

     It works better if you put vinegar directly into the bottle, roll up baking soda into a tissue, napkin, etc., then put the baking soda in the bottle, shake it, and then throw it. I’ve had some really powerful explosions.

     Here is another idea instead of using a bottle cap try a tissue! all you should do is before closing the container put a tissue and put baking soda on it and than close it.

     P.S: and make holes on the tissue

     try this put karbide into bottle about 60 grams of it then fill a baloon with peroxide (30%) about 100 ml of it, push it into bottle, add some MnO4 u get that in bateries, add some pressure iresistant explosive into foil put it into the cap screw the cap on the bottle and viola you have a grenade. When u shake the bottle and the baloon pops pure oxigen and acethyle will be generate as well as a lot of heat when explosive goes off that stuff will ignite creating an eplosion equivalent to 150 grams of black powder at least (that is if you do it right) anyways this is a very hard thing to do and quite dangerous, coz after the bottle is closed when the baloon pops u hav only 3-12 secunds to toss it aside. Good luck with it ^^. Btw ur neighbours might call the police coz of loud bang -_- so consider goin 2 km away from civilisation.

     For something way cooler, take a one liter vinegar can, wrap about two handfuls of baking soda in a paper towel. Stuff the wrapped soda in the top ofthe Bottle, skrew the lid on, and shake the bottle up until it gets rock hard. As soon as you are too terriffied to hold it any longer, throw it underhanded straight up
     and back up. When the bottle slamms into be ground, it will explode and rip the whole lid assembly off! LOUD!!
