A dry ice bomb is a simple bomb-like device. While the simplicity and ease of construction, high bursting pressure, and sound make the dry ice bomb attractive for recreational purposes, they can be unpredictable and dangerous.
Additional recommended knowledge
As frozen carbon dioxide warms inside a bottle, it sublimates to a gas. The pressure inside the bottle increases as the gas expands. Bombs will typically rupture within 30 seconds to 30 minutes, dependent largely on the temperature of water put into the bottle. A dry ice bomb may develop a frost on the bottle exterior prior to explosion. After explosion, a dry ice bomb will appear to have shattered, with the overall shape of the device intact. Dry ice bombs are most commonly used on their own to simply make a blast. They are not useful as weapons as the timing of the blast cannot be controlled.
Dry ice bombs have some serious risks:
Bombs which do not explode are a major safety problem. They cannot be left, yet cannot be safely approached.
Dry ice bombs are illegal in many jurisdictions.
In California the relevant law defines a dry ice bomb as: "any sealed device containing dry ice (CO2) or other chemically reactive substances assembled for the purpose of causing an explosion by a chemical reaction." A dry ice bomb explodes due to a physical phase change rather than any chemical process, but making one might be a felony that carries a fine of $10,000,
