Baking Soda and Vinegar Bomb




About: I am a Senior in California. I love running, hacking things, and making all sorts of stuff, from cardboard contraptions to electronic circuits.

Intro: Baking Soda and Vinegar Bomb

This is my first Instructable, and I'm making it for the Chemical Reaction Weekly Challenge. These bombs are fun and easy to make, and even funner to use.

Also, I am not responsible if you blow it up anywhere you shouldn't i.e. Around people, pets, public buildings, ect. THIS PROJECT CAN BE DANGEROUS! It can also be super fun, but be careful. Good luck, and have fun!

Step 1: The Supplies


- Vinegar (I used Apple Cider)
- Baking Soda
- Empty water bottle
- Small sheet of paper (For rolling baking soda in)

Step 2: Add the Vinegar

Fill the bottle up about a little more than a quarter of the way up.

Step 3: Prepare the Baking Soda

Lay the paper out. Cover it in Baking Soda. After that, roll the paper into the smallest tube possible, so that it will fit through the bottle opening.

Step 4: Lay Out the Bottle and the Baking Soda

Clear away your materials and lay out the bottle and baking soda. Get ready to put the baking soda in by removing the cap.

Step 5: Put the Baking Soda In!

Put the tube of baking soda in and screw the cap on as quickly as possible.

Step 6: Watch It Explode!

Once you have screwed the cap on tight, get out of there and watch it blow! You can wait a few minutes, or if you are impatient like me, you can throw it in the air repeatedly until it explodes.

Step 7: Explosion!

    This is not a good idea, I can tell you from personal experience. I made one of these with baking soda and lemon juice when I was a kid. I left it sitting on a shelf in the garage while I went inside to talk homework with my parents. Moments later I hear a BOOM followed by the shrillest scream I've ever heard in my life. Turns out my younger brother who was around 10 at the time had taken it and thrown it in the driveway. The cap blew off and hit him with incredible force right in the sweet spot (I kid you not!). His unit swelled up like a hot air balloon and he was for all purposes completely bedridden for the entire camping trip we left on the next day. True story. My brother still winces every time I bring it up.

    Hey, when you need to protect your home from an army of the undead,you'll be thanking him.Once agian, some basic safety logic goes a long way.

    This is a pretty cool idea. But if you guys want a better (no afence) and cool experiment keep reading on. Things you will need........

    1. Vinegar

    2. Jar

    3. Egg

    4. Patients!

    Put the vinegar in the jar and then place the egg in it with the vinegar and jar and then wait a few days. What happens is that the egg turns transparent and bouncy. This is my favorite experiment and I am a famous scientist!!!!!!

    Where do I get patients? Do I steal them from the local hospital?

    i know right?

    I love doing this. A fun idea is to put some crushed paint balls in the cap so it sprays paint everywhere when it explodes.

    made a smaller one of these one time and threw it at the wall repeatedly and it wouldn't blow up so i walk over to and stared at it and BOOM a foot away from my ankle... wish i had i video of my face :) ;)

    He he I remember making these in film containers by filling the hollow part of the lid with the soda. I then separated a tissue in half and secured the lid by pressing down. Shake and throw! Me and my brother used to put them on the cycleway and watch people pick them up through the hole in the fence. Haha good times. Thanks for bringing back memories.


    a good idea though is to put the backing soda in saran wrap and then put it in the bottle and screw three of the corners onto the caps. what that does is leave a open pocket so that when you shake it is when it starts to expand. there is so much time to run so you could problably walk away. good idea is to strap fire works onto the side of the bottle and put a wine cork were the cap is supposed to go.


    i love these bombs, i made one when i was about 12, i kept throwing it in the air and waiting for it to explode. after a while i picked it up and stared at it and it blew up in my hand. they are crazy fun even though i went deff for 5 minutes but they are pretty fun things to play with

    it sounded like a shotgun went off when I made one lol I did use a two liter and launch it out of an air cannon though ;)

    Great instructable! :) Im going to try this as soon as I get home! :D Just one question, how long does it take to blow up? Will I have enough time to run away after I screw on the lid?

    It depends on how much Baking Soda and Vinegar you put in. For me, it was about 2 minutes, so you should have enough time to do so. Good Luck!
