Dry Ice Bomb

Dry ice is solid carbon dioxide. At normal atmospheric pressure and temperature it sublimates (changes directly from a solid to a gas), resulting in a tremendous increase in volume. So what happens if you put dry ice in a closed container? Pressure quickly builds up and the container explodes. Dry ice is available for purchase at some large supermarkets or you may be able to ask for it at ice cream shops. (They use it to ship the ice cream.) A few pounds of dry ice will make several bombs.

dry ice bomb instructions: plastic bottle, dry ice

danger level

  • negligible
  • moderate
  • high
  • do not do this

tools

  • C. Hammer
  • D. Glove
  • E. Sharp knife

materials

  • A. Plastic water bottle or similar
  • B. Chunk of dry ice

how-to

  1. Use a hammer to break the dry ice into small chunks that will fit through the neck of the bottle.
  2. Optionally, you can lightly score the side of the bottle with a knife. This creates a weak spot where the bottle can break cleanly, rather than just having the cap blow off. Experiment to see what works best.
  3. Insert 15-20 chunks of dry ice into the bottle. Adding more will make your bomb explode faster, but not necessarily with more force. Use a thick glove to protect your hand. Dry ice is -109.3°F and can cause frost bite very quickly.
  4. Pour in enough water to cover the dry ice. This dramatically speeds up the sublimation. Quickly cap the bottle and toss it somewhere safe. (Away from yourself and anything else living.)
  5. Wait for the bottle to explode. Generally it will take 10-30 seconds, but it could take longer. Be very careful about approaching or touching a bottle that hasn’t exploded. The pressure will probably keep increasing for a long time and it could blow at any moment, especially if you disturb it.

    Water bottles are good for maybe 80 psi. Soda bottles, like Coke, etc., don’t rupture until around 200+ psi, so they will make a much bigger (and more dangerous) blast. Larger bottles (1, 2, 3 litre) have proportionately more gas volume, and therefore more power, as well.

    Put dry ice and water in a regular water bottle just like the instructions say but be sure the bottle is sitting upright and put a 5 gallon bucket over it. When the bottle explodes the bucket will shoot about 50 to 85 feet in the air.

    The danger is very much overrated. If plastic bottles are used, shrapnel is relatively minimal, and even if it does hit someone it’s not moving fast enough to do any real harm. Hearing and eye protection are somewhat of an issue. These both can be resolved by wearing protection for the given areas.

    There’s definitely danger involved. If you use too much dry ice or too warm of water, or if the bottle has structural defects, it can explode prematurely (i.e., while you’re still holding it). But, if you’re careful / experienced, the danger is minimized.

    @ tBC: Danger itself is not minimized with experience! An ability to see and deal with dangerous factors is, however. Anybody who is unaware of the possible consequences of what they are doing, simply shouldn’t. In a perfect world, nobody would lose a hand or eye because they took their attention off the task in front of them.

    Every single bottle you use is a new set of circumstances. Examine them all carefully, test for leaks, and WEAR EYE PROTECTION. A pair of sunglasses will not only make you look cool, they’ll keep shrapnel out of your eye.

    Using a 0.5L or 1L Coke bottle allows you to go to pressures above 100 psi. The triple point of CO2 is about 5 atm = 70 psi, and so if you don’t use water, you will get liquid CO2, unobtainable at normal atmospheric pressure. BE CAREFUL handling the lliquid CO2, since it is still a bomb! (Use goggles!) I used a broom handle with a two-pronged fork taped to the end, so that I could pick up & manipulate the bottle. Cool stuff!

Then pour a small amount of liquid nitrogen into a plastic bottle, screw the cap on, and throw into a pond or stock tank. The gas escaping from the hole will propel it like a jet boat. Be warned: Liquid nitrogen is dangerous. If (usually) ice forms over the hole, the bottle will seal and explode similar to the dry ice bomb. Hand and eye protection is a must.

    This is some great fun, another warning though. While im not sure why you would set off one of these bombs in a closed area, but you shouldn’t. This is not because of the explosion, which can be dangerous, but rather if the so-called bomb produced enough carbon dioxide in a sealed area it can displace all the oxygen from the air. Meaning you could possible suffocate yourself.

    The higher the pressure the bottle is supposed to hold the louder the noise. Size also makes a difference. The Three liter bottles are WAY loud but I like the Tonic Water bottles because they have a very high burst pressure. Don’t even bother with water bottles as the burst pressure is much lower, only pressure type bottles. Oh, if you don’t use water these things are great time-bombs!

So i am hoping to see this flick.

    ChemE the liquid nitrogen is colder then dry ice so when its in the bottle it boils releasing a gas then the bottle eventually breaks causing the rest to shoot every were in the garbage can full of water which is warm than the liquid nitrogen which yes cause the garbage can to expand because of the pressure of the gas being released. but i was saying liquid nitrogen works better because it is colder then dry ice.

    you don’t have to detonate, basically as soon as you seal the bottle airtight, the pressure builds up from the vaporizing dry ice and finds the weakest spot to blow out.

    Just a thought; wouldn’t sinking the bottle in the lake with a brick mean there would have to be more pressure for it to burst? Isn’t the pressure of water exerting two atmospheres of pressure at a depth of only 33 feet? So, the pressure inside the bottle would have to be high enough to overcome both the resistance of the bottle and the increased pressure from the water trying to compress the bottle. At about 100 ft of depth, there has to be an additional 59 pounds of pressure to counteract the water. So, if you’re gonna try it, stick to the shallow end of the pool boys.

    Where I come from, there is hardly any “remote” places, so it absolutely is not possible for me to ever try this awesome experiment. However, I did watch a video on youtube where some people used the Dry Ice Bomb as the “explosive” in a bazooka. They got a metal pipe, with one end sealed. It was a VERY STRONG reinforced pipe. They used it like a mortar, threw in the Dry Ice Bomb, threw in a Potato and aimed it. Let me tell you it flew incredibly high. Perhaps a new heatless bazooka for the army?

    Well anyway, what I thought off was instead of using a potato, why not use ANOTHER Dry Ice Bomb? If you make sure the fuse for the “explosive” is faster than the fuse for the projectile, you could theoretically make the projectile explode in mid air. Add some food colouring and wala, flameless fireworks! I don’t think this has been tried before due to the obvious danger, but with a helmet, gloves and thick clothing it should not be too dangerous.

    1. Fill 50ml conical tube with 5ml water
    2. Steady the empty 5 L graduated cylinder between your neck and shoulder
    3. In VERY quick motions perform the next steps
    a. drop a couple chunks of dry ice into tube.

    4. Aim and wait…
    It typically didn’t take long.

    The weakest portion of the conical tube was the thin plastic of the lid, so the blast was contained and propelled the conical tube forward out of the tube. These tubes can cause substantial damage. I’ve seen the plastic conical pieces submerged up to an inch into a plaster wall. Don’t aim it at a person.

    Fellow ordnancemen: 20-ounce Pepsi bottles will contain the most pressure–much more than Coke or 7-Up. We all know that pressure is good. Personally, my favorite method is to put about 1 inch of dry ice in the bottle, with no water. It takes about an hour to detonate this way. This way, you will have plenty of time to formulate an alibi. Also, it is much louder. I think it’s because the pressure builds up more gradually, and the plastic becomes more brittle because of the cold. You can hear it for BLOCKS. (I love to lob one of these bad boys into my neighbor’s yard, then wait for the police to show up when it goes BOOM.) Another favorite tactic is to insert the assembled device into a watermelon that’s past its prime. The aftermath is absolutely spectacular–Kermit the Frog turns suicide bomber.

    i think the thing that kills the fish is the initial explosion. its kind of like a depth charge, that boats drop to destroy submarines, the explosion displaces so much water in the area that the pressure around it increaces and crushes the hull of the submarine, or the internal organs and fillets of the fish.

    I did this last week with some good results, depending on how you view the situation.

    I made a dry ice bomb at friends house, but I placed it far away from wherever anyone might happen to walk. It was someplace in the surrounding forest. We waited for it to explode, which took about an hour and a half. When the first hour elapsed, a few people and I went for a walk on the street, and when we got back, the thing exploded. No one was anywhere near it, but it was extremely loud, some people were comparing it to sticks of dynamite.

    Two lessons:
    1.) Dry ice bombs can build pressure for ridiculous amounts of time.
    2.) You could potentially rupture an eardrum if you’re too close.

    if you have any of those non-chemical fire extinguishers, you can take and discharge them into a pillow case (keep it tight against the nozzle as the lever is pulled leaving a little slack for the frozen CO2 to collect)
    its a great way to get ahold of dry ice before you’re 18, kids can buy fire extinguishers, not dry ice…..

    and, as an added bonus, the dry ice forms into something that vaguely resembles snow, so you can get it into a bottle quite easily.

    I tried this the other day and had great luck with it: If you’re lucky enough to get your hands on a 200mW green laser and you get about 10 ft away after you have made the DIB (squeeze the bottle), you can point the laser at a certain spot from a distance and weaken that part of the bottle enough that it will blow out from that part of the bottle. Allowing you to “point” the explosion in any direction you would like. If your able to do it you won’t be disapointed! IF YOU’RE GOING TO TRY MAKING ANY DIB THEN DON’T BE STUPID, WEAR PROTECTION!!!!

    any ideas on what would happen if fired from a trebuchet? so far it’ll launch a basketball about 100 yards, something with more mass (perhaps a 2 liter bottle filled with dry ice and water) should reach upwards of 150-200 yards because of reduced air resistance. guess there’s only one way to find out, although finding a 200 yard stretch is hard around here, and moving an 850 pound counterweight isnt easy

    I made a dry ice bomb using a small plastic Coke bottle. Once it was ready, I placed it in my pool, put a plasic garbage can lid over it and pushed it toward the middle of the pool. Since the bottle was surrounded by water there was no plastic shrapnal deposited anywhere but the pool. The explosion was an awsome very low decible concussion that was felt inside the house. At first I was worried that it may have cracked my pool but after doing some research I realized that was very unlikely especially since it was near the middle of the pool. I would recommend this process as the safeest I’ve seen for anyone with a desire to try this. Just make sure no onone is in the pool at the time.

    Don’t know if my friend actually invented the technique - but I first heard about it over 20 years ago while I was in college. My friend tried it at his house and the police came out and darn near arrested him. Over the ensuing years we went on several dry ice bombing expeditions. Quite memorable as we collectively saved hundreds of bottles and bought about the same poundage of dry ice for each trip. My friend even figured out how to grind the dry ice to bottle neck sized chuncks with a car battery powered ice crusher. Much easier to fit in the bottle and faster reaction time - so yes, squeezing the bottle is a great idea. We never had any serious injuries but did have some close calls before we started wearing both ear and eye protection. Got ticketed by some park rangers too for disturbing the peace. Blew a chained lid off a garbage can too - so yes, these things are extremely powerful and load - we’re talking CANON loud! If you are out in the woods? The extra CO2 will attract ticks and other bugs like CRAZY since this is one thing they sniff to find you! Safe way to defuse a pregnant bomb? BBgun.

    Pretty powerful using a 2 liter plastic Pepsi bottle. It is a felony in a lot of states. I’m in Calif. and you can be arrested. You can google “dry ice bomb” and find the wording of a bomb consisting of a chemical reaction is against the law. Dry ice and water is technically not a chemical reaction. The dry ice sublimates into a gas from a solid. I did this with my daughter for her science project and the explosion was louder than a shot gun using the 2 liter bottle. We put a 5 gallon bucket over the next one. It blew the bucket in half and shot it up about 20 feet. Wear eye protection and don’t touch the bottle after it is capped to be safe. Raley’s grocery store has dry ice and sells it for one dollar a pound.

    We made a dry ice cannon out of a cut down piece of exhaust stack from a new truck at work. Welded an old pulley on the bottom to seal one end. A 2 liter bottle would fit with a little play on the sides. One person would fill the 2 liter with ice/water while another person wadded up some shrink wrap. The shrink wrap acts as a wadding & helps seal the tube. Throw the 2 liter in, stuff the shrink wrap in & top it off with the projectile of your choice. Another 2 liter with water works well. They launch hard & fast. It works okay without the shrink wrap, but we had plenty at work at our disposal.

    I overheard a story about someone who was in trouble with the law for something that sounds a lot like this. Instead of treating it as a “bomb” case, they were being charged with “tampering with a pressure vessel”; because, the pop bottles are designed to hold pressure. This made the case a felony. It was a novel interpretation of the laws written to stop people from tinkering with industrial boilers and steam systems.

    You guys should really treat DIB’s with the same respect that you would give dynamite or other high explosives. Just ’cause they’re easy to make doesn’t lower the danger. You have to get back a lot more than 50 feet if you are detonating dynamite so use the same precautions when blowing up a dry ice bomb.
    Make sure to use cold water and ALWAYS ALWAYS squeeze the bottle a bit to give yourself a bit more time. Some guys set one under a mailbox and it flew 25 feet into the air so be warned.
    There’s a way to make a mentos bomb but I decided not to say how to….I don’t want to feel responsible for some frikkin dumb ass blowing up some kids, himself, herself or having anyone get hurt from my info. There’s already enough on this thread to do serious damage.

    My friend, his girlfriend, and a couple of their friends made a works bomb about 100 yards out into the woods by her house… Trust me, don’t do that… He shook it, stood there and got the words “What the ****? It’s not doing anything!” out before it got hot and burned his hand. He tossed it as hard as he could, and about ten seconds later, it detonated with an incredible boom. His girlfriend’s father sat upright in bed from a sound sleep. He came running outside, thinking someone was playing with shotguns. They put it in an old firepit, so there was about a twenty foot cloud of ash. Like a previous comment mentioned, works bombs are prone to premature detonation… Don’t be like Achmed The Dead Terrorist… Don’t be singing “Oh holy crap! I think I blew my foot off!”

    The “receipt” is the same as with dry ice :)
    Also I know some other easy ways to make “BOOM”, but my english is not thery good, so I won’t talk about it for safety reasons :)
    And please, if you do this, get as far away from the other peolple, as you can and DON’T TOUCH the “BOMB” that didn’t explode! You still can explode it by putting another “bomb” nearby.

    Hey if u make dry ice bomb just buy a few pounds of dry ice.And i try this to my house and school.I show it how it will more better explosion.

    1.Find a 2liter bottle(more better if you use sprite 2L)i bought from grocery store.If u see it is very big for you try 20oz. pepsi bottle.
    2.Being ready to try this use hammer,and a needle nose pliers and find a clean pizza box and clean it (to put the dry ice and crush it to pieces).
    3.Buy a dry ice in big grocery store like Wal*Mart and u ask the meat vendor (it is used to freeze the meat)and i buy 14 pounds of dry ice.
    4.And ready!(more better if u do this on woods)I fill the 2L bottle with half water and insert 10 dry ice chunks into the bottle.And i screw the cap on in 35 secondsit explodes! the shock wave is imppressing!it felt it on many yards away.

    Warning!the dry ice has a temperature of -75 degree
    Celcius and -109 Farenheit so use insulated gloves.For storing dry ice store it in the insulated container because dry ice is heavier than air and the pressure builds up in the container it will explodes(if you store it in the not insulated container)thats it!happy bombing!

    you can also make a nice boom useing a plastic bottle; several small balls of aluminum foil and “The Works, Toilet Bowl Cleaner” but it HAS to be that brand, it will not work with any other toilet bowl cleaner. Be Careful and do it quickly, it can build pressure very fast.

    One time my friend had some dry ice, and he put it in a bottle, not knowing what would happen. Suddenly, the cap shot off really fast and hit him straight in the *ahem*. I don’t think he’ll be having any children.

    All of you should definitely try this!
    Fill the bottle up half way with dry ice, piss in it, and cap it. Hold it to your chest very, very tightly with both hands, keeping your head tucked down low towards it, and just wait.
    Yes, definitely, you should all do this because I’d rather you idiots didn’t piss in MY gene pool.
    Anyone saying this isn’t dangerous, or doing this maliciously to destroy others’ property deserves to lose a few fingers at the least. But since I don’t believe in “rehabilitation”, I’d rather you all just gave the bombs great big hugs.
    Ta-ta, kiddies.
