Dry Ice Bomb exploding in Water.
A dry ice bomb is a simple bomb-like device. While the simplicity and ease of construction, high bursting pressure, and sound make this dry ice activity appealing for recreational purposes, it can be unpredictable and dangerous, and has led to many injuries - and dry ice bombs are illegal in many jurisdictions.

Overview
A dry ice bomb is made from a container such as a plastic bottle, water, and dry ice. The bottle is filled about quarter full of water, some dry ice is added, and the container shut tightly. As the solid carbon dioxide warms inside a bottle, it sublimates to a gas. The pressure inside the bottle increases as the quantity of gas increases with limited room to expand. Bombs will typically rupture within 30 seconds to 30 minutes, dependent largely on the temperature of the air outside the bottle.[1] A dry ice bomb may develop a frost on the bottle exterior prior to explosion.[1] After explosion, a dry ice bomb will appear to have shattered, with the overall shape of the device intact.[1] Dry ice bombs are most commonly used on their own to simply make a blast.
Dangers
Dry ice bombs have some serious risks:
- Premature explosion. Burst pressure can occur within seconds, injuring the handler.
- Dry ice is very cold: –78.5°C (-109.3°F). The explosion can carry shards of dry ice that had not sublimed.
- The shock wave can be extremely loud and hearing damage can occur even at substantial distances.
- The blast can propel fragments of the container at very high speeds causing cuts and puncture wounds.
Dud bombs which fail to explode are a major safety problem. They cannot be left, yet cannot be safely approached. Unexploded bombs can be shot or otherwise ruptured from a safe distance. Injuries are common, with glass bottles in particular posing a risk of serious injury.[2][3][4][5]
Legality
Dry ice bombs are illegal in many jurisdictions, arrests are frequent[6][7] and can lead to imprisonment.[8]
- A law in California that defines "destructive device" includes a list of "weapons" including "[a]ny sealed device containing dry ice (CO2) or other chemically reactive substances assembled for the purpose of causing an explosion by a chemical reaction.[9]"[10]
- In Nebraska [11] and in other areas the noise generated may violate local laws.
- Arizona prohibits dry ice bombs if there is an intent to cause injury, death, or damage to the property of another,[12] as well as their possession by "prohibited possessors" such as convicted felons and illegal immigrants.[13]
- Leaving an unexploded dry ice bomb can be construed as public endangerment, and can and will damage public or private property.
- In Utah simple possession of a dry ice bomb and similar pressurized chemical reaction bombs is a second-degree felony. "Thirty to 50 times a year, the Salt Lake bomb squad gets called out for one of these explosives (dry ice bomb). The injuries they've seen are life-changing: everything from blown-off fingers to extreme burns; some have lost their hearing and eyesight."[14]
