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.

We used to do this with gatorade bottles and MRE heaters. The gatorade bottles are thicker and take more pressure to burst. Just don’t do it around flame, as the heaters make hydrogen gas.

The danger is not over-rated. Things that explode should never be treated lightly. Squeezing it is good advice.

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.

Long story short, one of em ended up in a cop car and both of them almost got in some serious trouble. Thanks to the quick action of one of the two morons, the “bomb” was diffused before the cops got a chance to call the bomb squad.

If you do this, don’t be stupid, do it at home and try not to attract to much attention to yourself.

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!

When I was younger I had unsupervised access to liquid nitrogen. Punch a small hole in the plastic cap first. 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!

Just conversed with my prof. and he said that if you filled the 1 liter (or more) bottle with liquid nitrogen. Then tossed that into to garbage can full of water that it would be a bigger explosion. when the bottle of liquid nitrogen explodes it sends the liquid nitrogen shoot out and because it is much colder than dry ice that it instanteously turns the surrounding water to a gas and cause it to explod the garbage can. my professor said they filmed it and i haven’t done it yet. 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.

BTW, 2 liter bottles look pretty devastated after the explosion. how much pressure is this really exerting?

I think he meant how do you detonate from a distance. I’d just use a pellet gun, or a teeny firecracker or something. Maybe some steel wool wrapped around it, put 9 volts through it it gets hot enough to burn… might cause the bottle to rupture and explode.

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.

even in a lake the pressure is far more than you need to make the bottle explode. I have tried it on a pretty big lake and I used a boat to get out far I dont know how deep it is because I cant swim far enough down even being a good swimmer so no problems there however it dose take slightly longer to go off.

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.

When I was working in a lab at UPenn, there was a time when my coworkers would shoot ‘bazookas’ in the lab. A ‘bazooka’ consisted of a few chunks of dry ice, about 5ml of water, 50ml conical (falcon) tube and a 5 liter graduated cylinder.
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.
b. tighten lid on conical (HURRY)
c. release/slide conical down graduated cylinder (Lid first, conical facing out of 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.

I stood next to it for another 5 minutes just waiting. Again nothing.
About 5 minutes later, I had actually forgotten about it… KA-Fuggin-blam. It was louder than any gunshot I’ve ever heard. Particles were still falling about 1 minute later. You could hear it hitting the leaves. The guy a few feet away from me hurt his eardrum. It was extremely loud. We were about 50 ft. from it when it went off. I had no idea it would be that powerful.

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 saw a youtube video of some guys shooting a dry ice cannon, the first shot they did using a dry ice bomb as a projectile worked amazingly well, firing high up and blowing up on impact, the second shot they did blew up in the piece of pvc, thus destroying their cannon barrel.

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.

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.

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.

do this with a gatoraid bottle, the kind with the cap you dont have to take off to drink. It wouldnt explode so i tossed it onto my driveway, the cap shattered into 50 pieces and launched the bottle 50 feet. also fun to get a pot of boiling water and drop dry ice in, lots of fog

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.

Legal Warning:
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.

I tried this for the first time today…3 different times, no explosion. Maybe I got scared and didn’t tighten the cap enough or something. Now I have 3 bottles (2 liter) in my back yard. I have a pellet gun…will they explode if I shoot them or will they just fizzle?

An alternative to the dry ice that is easier to obtain and works just as well is aluminum foil and “The Works” toilet bowl cleaner. Tear off pieces off the foil and loosely ball it up to about the size of a marble. Put 6 or 7 balls of foil in the bottle and put 3 or 4 squirts of the toilet cleaner in. Cap it off, give it a few shakes and get away from it. Downside is, you have toilet bowl cleaner flying around in addition to the explosion, and is still just as illegal, so don’t do it!
