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. Dry ice bombs are ilegal in many jurisdications.

Overview

A dry ice bomb is made from a container that can be easily sealed (typically 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 shock wave can be extremely loud. Permanent hearing damage can occur even at substantial distances.
  • In many areas dry ice bombs are illegal. Some documented examples include the U.S. states of California,[2] and Nebraska [3] but 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,[4] as well as their possession by "prohibited possessors" such as convicted felons and illegal immigrants.[5]
  • Leaving an unexploded dry ice bomb can be construed as public endangerment, and can and will damage public or private property.

Arrests are frequent.[6][7] Injuries have been reported; glass bottles in particular pose a risk of serious injury.[8][9][10][11]

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.

Legality

Dry ice bombs are illegal in many jurisdictions.

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."[12]

Popular culture references

  • The book One Day in the Life of a Fool by Jeremy M. Gates includes a story about a dry ice bomb which failed to explode as planned, and later exploded accidentally after someone took it indoors.
  • An episode of Discovery channel's Time Warp features several dry ice bombs filmed on high speed camera; one on a tabletop and three in a metal tank.
  • Episode 5x23 (Iced) of CSI features a toilet bowl blown to smithereens by dry ice, first in a dorm lavatory, then in the laboratory by Greg Sanders.

  • Leaving an unexploded dry ice bomb can be construed as public endangerment, and can and will damage public or private property.
  • Utah has taken a strong stance against dry ice bombs, labeling and treating them as "homemade explosive devices". Utah recently made simple possession of a dry ice bomb and similar pressurized chemical reaction bombs a second-degree felony; multiple people have been tried as felons for intentionally exploding gas-pressure bombs.[5] One must be 16 years or older to purchase dry ice in Utah and ID to verify age is commonly requested. If a dry ice bomb causes injury or if the intent of the bomb is to cause personal injury or damage to structures, possession is a first-degree felony; if detonated within a close radius to a school, church or the like, the charge is also bumped from a second to a first-degree felony.[6] The Utah bomb squad says this hard stance is due to: "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."[7]

Arrests are frequent.[8][9] Injuries have been reported; glass bottles in particular pose a risk of serious injury.[10][11][12][13]

The cast believed that once one of the three bombs exploded it would blow up the other two bombs; the first bomb exploded rupturing the tank without exploding the other two 2-liter bottle bombs, and the cast and crew had to run and seek cover.
  • Episode 5x23 (Iced) of CSI features a toilet bowl blown to smithereens by dry ice, first in a dorm lavatory, then in the laboratory by Greg Sanders.
